70 Volt Applications

The Sonance Invisible Series IS8T includes a 70V/100V Sonance Laminated Core Transformer with an adjustable tap.

Setting the 70V Tap

1. Using a #2 Phillips head screwdriver, remove the two screws securing the terminal cover plate.
2. When using speaker wire without conduit, run the wire through the hole on the terminal cover plate. Wire needs to be clamped as required by national or local codes. Connect the wires to the terminal block, being certain to connect the positive wire to the terminal marked '+' and the negative wire to the terminal marked '-'.
3. When using conduit, attach the conduit connector to the terminal cover plate, then connect the wires to the terminal block, being certain to connect the positive wire to the terminal marked '+' and the negative wire to the terminal marked '-'.
4. Using a flat head screwdriver, set the transformer tap to the correct tap setting for your installation. We strongly recommend testing the system with music to determine the correct output level.
5. Run the speaker wire from the first IS8T speaker in the chain to the amplifier terminals. Connect to either the right or left channel (+ and -) of the amp. (Sonance DSP 2-750 MKII shown in illustration).

NOTE: Amplifier bridging is NOT supported when in 70V configuration.

WARNING: Do not mount and finish over the speaker until you have selected the necessary tap setting to achieve the desired volume level. After selecting a given tap, play the speaker with an actual audio signal to verify the speaker provides adequate volume. If necessary, re-select a lower or higher tap setting.

A dial graphic shows the 70V/100V tap settings, ranging from 7.5W to 60W for 70V and 15W to 60W for 100V, with a 4-ohm bypass option.

Product Preparation

Amplifier Selection

Sonance DSP Amplifiers are recommended for use with the IS8T speaker. For 70V/100V applications, the Sonance DSP-2-750 MKII is recommended. These amplifiers have preloaded curves to optimize the performance of Invisible Series speakers and woofers. Preconfigured curves for various finish types and thicknesses allow for effortless calibration without additional measurement equipment. Sonance DSP Amplifiers are rated down to 4 Ohms and are stable to 2 Ohms. Never run more than two Invisible Speakers in parallel on one amplifier channel.

NOTE: Pay attention to Sonance IS speaker rated RMS power handling. Select an amplifier with max RMS watts per channel at 4 ohms that closely matches or is less than the IS speaker's rated power handling (see page 16). Damage to the speaker or installed finish may occur if the speaker is overdriven.

Wire Gauge - 70V/100V Systems

The most common wire used on commercial 70-volt systems is 18 gauge, 2 conductor, stranded, and jacketed without a shield. The wire starts at the amplifier location and is paralleled at each speaker location.

Wire length using 18 gauge is appropriate up to 700 feet with a 100-watt load. Doubling the load (sum of tap settings) reduces the footage by half, to 350 feet. Halving the load may double the acceptable wire length; for example, a 50-watt load is safe over 1400 feet of 18 gauge. Using 16-gauge wire extends the allowable run length by approximately 35%. For instance, a 100-watt load can go 700 feet on 18 gauge, but the same load can be placed on 1100 feet of 16 gauge.

Excessive wire resistance negatively affects sound quality, reducing bass definition and potentially attenuating high frequencies. Amplifier power is also wasted in the wire, reducing maximum output level. Refer to the chart below for appropriate wire gauge selection.

Wire Resistance Table

Wire Gauge - Low Impedance Systems

For low impedance systems, total wire resistance should be less than 10% of the speaker impedance. For the 4-Ohm nominal impedance speakers, total wire resistance should not exceed 0.4 Ohms. Excessive wire resistance negatively affects sound quality, reducing bass definition and potentially attenuating high frequencies. Amplifier power is also wasted in the wire, reducing the maximum output level of the system. Refer to the chart above when deciding on the appropriate wire gauge for your installation.

Speaker Location

Invisible Series IS8T speakers offer a 170-degree hemispherical dispersion pattern, allowing for a wide range of applications and installation locations. For wall installations, speakers should be mounted at least 7 feet (2.13 meters) above the finished floor (AFF) to avoid damage. For ceiling installations, space speakers evenly for optimal coverage. Ensure speakers are not covered by cabinetry, draperies, art, or crown molding. When installing in walls, face the Wave Flex Drive Unit away from the ceiling. When installing in ceilings, face it away from the walls. Ensure the back of the speaker has clearance and is not adjacent to building systems like HVAC, electrical, or fire sprinklers, which could violate codes or affect sound quality.

Installation Accessories

Space savers and preconstruction zip rings assist in trade coordination and are recommended for best results. Space savers reserve precise dimensions and location during construction, protecting speaker wire. They allow for delayed speaker installation until just prior to the finishing stage, reducing risk of damage or theft. For projects with many speakers, preconstruction zip ring brackets provide a guide for drywall cutouts using a drywall zip tool. Zip rings are made-to-order; contact your Sonance representative for pricing.

Space Saver Part Numbers:

• IS-SAVER-M (for IS8T): 93493 (4-pack)

Finish Materials

Prior to speaker installation, verify that the topping compound and final finish are flexible materials (e.g., slow-setting drywall mud, wallpaper, acrylic-based Venetian plaster, thin wood veneer) and will not exceed 3mm (1/8").

NOTE: For optimal performance, a finish thickness of 1.0mm to 1.5mm (about 1/16") is recommended. Excessive topping compound can adversely affect sound quality and installation durability. For wood veneer finishes, use only 20mil (0.5mm) veneer with paper backing.

NOTE: Do not use hard-setting or stiff materials over the surface of invisible speakers, such as fast-setting drywall mud ("hot mud"), genuine Venetian plaster, stucco, metal panels, or tile.

Product Management

Follow installation instructions precisely for outstanding speaker performance and true invisibility. Flawless execution requires project management and close coordination with drywall and finish trades, the General Contractor, and the client. Follow these best practices to prevent unmet expectations and rework:

• After speakers are connected and screwed in, but before drywall mudding, taping, or finishing, schedule a walk-through with the client, General Contractor, and finish manager. Listen to each speaker for a few minutes to identify any anomalies or performance issues.
• All attendees should sign off on audio performance, speaker-by-speaker and room-by-room. Use a checklist and have parties sign and date to acknowledge expectations are met.
• Review installation steps with the finish manager, emphasizing the use of only enough flexible material to make speakers disappear. The recommended target is 1.0-1.5mm (about 1/16"), with a maximum of 3mm (1/8"). Review recommended materials on pages 5 and 14.
• Use the Sonance DISC system and DG-1 depth gauge (SKU 93491) to validate finish thickness. Lending the gauge to the finish manager is helpful.
• Once the finish material has completely dried, perform another room-by-room listening check. If speakers sound different from the pre-finish test, the finish thickness likely exceeds 3mm (1/8"). Correct by removing material.
• Remember, once flooring and furniture are in place, removing excess finish material becomes costly and complex.

Effective project management, sign-offs, and proactive communication prevent unexpected results and ensure consistent, beautiful installs.

Installation Detail - 16" (406mm) On-Center

A detailed diagram illustrates the installation of the IS8T speaker into a 16" (406mm) on-center stud bay. It shows framing support, the use of 1/8" (3mm) shims around the speaker perimeter, stainless steel screws, and the application of topping compound or flexible finish material over 1/2" (12.5mm) or 5/8" (15mm) drywall.

Retrofit Installation

1. Remove the included cutout template that is taped to the front of each speaker.
2. Locate the studs in your install location and mark the centers of the studs/joists. Position and affix the template so that it is perfectly centered on both left and right studs.
3. Mark around the template and remove. NOTE: We highly recommend you keep the cutout template. It is an important tool that will help identify the measurement locations for the Sonance DISC system during the finish validation phase.
4. Before proceeding, perform an obstruction survey to be certain that there are no studs, conduit, pipes, HVAC ducts, pocket doors, etc. in the wall cavity that will interfere with the speaker.
5. Cut the drywall using a drywall saw along the top and bottom and a utility knife along the stud centerlines. An oscillating power saw is recommended for faster, cleaner results.
6. Remove drywall from opening. This should expose only 3/4" (19mm) of each stud/joist or half of the stud/joist surface. Remove any exposed drywall nails or screws.
7. Test-fit the speaker into the opening, verifying that the center diaphragm area is even with the drywall edges. If necessary, trim the edges of the drywall to properly accommodate the speaker.
8. Run speaker wire from the amplifier and audio component location to the cut out holes for your speakers. See wiring chart on page 5.
9. We recommend that you reinforce the top and bottom joint locations with a face-block-oriented 2x4 or 3/4" (19mm) plywood. See the construction diagrams on page 7 and STEP 2 on page 9. Ensure there is a flush, level surface around the full perimeter of the speaker location before proceeding.
10. Proceed to STEP 9 on page 10.

Images demonstrate the process of using a template to mark drywall, cutting drywall with a saw and knife, and exposing stud surfaces.

New Construction Installation

1. Run speaker wire from the amplifier and audio component location to desired speaker locations. See page 5 for wire gauge chart.
2. We recommend that you reinforce the top and bottom joint locations with a face-block-oriented 2x4 or 3/4" (19mm) plywood. See the construction diagram on page 7 and the chart below for opening height dimensions. Product dimensional drawings are available on www.sonance.com. Ensure there is a flush, level surface around the full perimeter of the speaker location before proceeding.
3. Place space saver, preconstruction zip ring bracket, or both in desired speaker location. See page 5 for when to use space savers and zip rings. Space savers are recommended for every new construction project. Zip rings are recommended as a time-saver on very large projects with dozens of invisible speakers.
4. Use the wire management built into the space saver/zip ring to keep your cables in place. With the aid of a level, screw the space saver/zip ring to the studs, making sure it's centered horizontally.
5. Complete drywall installation to the rest of the room, including the surface around the speakers. NOTE: Sonance recommends using the included stainless steel screws around the speaker locations. This is to avoid interfering with the Sonance DISC system depth gauge operation after install. Though this is not required, it will improve the accuracy of finish thickness measurements later on.
6. Remove the space saver, if applicable. Hold onto the speaker wire attached to the back and pull it through the opening, being careful not to damage the surrounding drywall. The space saver can be kept for future installations or recycled.
7. OPTIONAL: If the zip ring was also used, cut the drywall at the speaker location using a zip tool and the zip ring as a guide. Be sure to cut along the outside edge of the zip ring. It will stay in place permanently.
8. Install shims to your framing as needed. Half inch (12.5mm) drywall does not require shims in most cases. If you are using a thicker substrate such as 5/8" (15mm) drywall, we include a thick 1/8" (3mm) shim to bring the speaker flush to the installation surface. We also include a full set of thin 1/16" (1.6mm) shims to make installation in a variety of substrates easier. NOTE: When using shims, make sure all 4 speaker edges (top, bottom, and sides) are supported for a flush install surface around the entire perimeter of the speaker.
9. Connect the speaker wire from your wall or ceiling to the terminals on the speaker.
10. Place the speaker into the opening. In a ceiling installation, do not hold the speaker in the center of the diaphragm. Hold at the edge of the frame and get assistance from a helper. Secure the speaker using one of the included stainless steel screws in each corner (use at least 4 screws total for this step). NOTE: The best practice is to use stainless screws to secure the drywall surrounding the speaker as well. Unlike standard drywall screws, these are non-magnetic which will improve the accuracy of the Sonance DISC system later on in the finishing stage.

Pre-Finishing Testing Guidelines

Once a finish is applied to an invisible speaker, it will be too late to go back and fix any audio connection or installation problems.

Installation Fit Test

Lightly place a straight edge across the face of the speaker to verify that the diaphragm of the speaker is co-planar with the surrounding drywall and has been installed correctly. Adjust shims if necessary. It is normal for the beveled edge of the speaker to be recessed from adjacent drywall.

Audio Test

Connect a high-quality audio source and Sonance amplifier to the installed invisible speaker for best results. Adjust the output for a moderate volume level consistent with how the speakers will be used in the space. Play music to check for overall fidelity and listen for any buzzes or rattles. We also recommend a slow tone sweep from 20Hz to 5kHz to help pinpoint any buzzing that could be caused from loose studs/screws/drywall, cable vibration, or rattling of outlets, lighting components, construction fixtures, etc.

Fix any installation or audio issues before moving on to the next steps.

We highly recommend active project management practices as described on page 6. Only after passing these testing guidelines should you proceed to the finishing stage.

Finishing Instructions

NOTE: Drywall finishes can range in various levels of smoothness. For invisible speaker installations, we recommend at least a level four finish where drywall seams are all feathered out and sanded. For best results, we recommend a level five finish where the entire wall plane is skim-coated and sanded for smooth consistency.

1. Fill the gap between speaker and drywall with 20-minute fast-setting joint compound ("hot mud").
2. Feather all edges.
3. Allow hot mud to set slightly before applying mesh tape.
4. Place mesh tape over the drywall seams. Overlap tape slightly.
5. Do not tape over the raised portion of the speaker.
6. Allow hot mud to fully cure and harden.
7. Once hot mud has fully cured, cover joints with slow-setting compound.
8. Feather all surfaces around the joints and up to the raised portion of the speaker diaphragm.
9. Allow first coat to fully cure. This can take 12-24 hours.

NOTE: DO NOT use fast-setting drywall compound ("hot mud") to cover the speaker; it is not flexible enough to provide a durable finish for invisible speakers. Instead, we recommend a lightweight all-purpose joint compound to cover joints and feather up to the surface of the speaker. Lightweight, easy-sand topping compound should be used for covering the speaker.

IMPORTANT: If a perfectly flat finish is achieved at this point, you may opt to proceed to the priming and painting phase. This is what we refer to as a "Finish Up To" installation. In this case, we recommend multiple layers of paint to achieve a shadow-less, even blending of color.

We highly recommend a "Finish Over" process where an additional skim coat is applied over the entire speaker and blended into the surrounding wall plane. A Finish Over process typically takes less time to complete versus Finish Up To because fewer layers of paint are needed. And with the skim coat over the entire surface of the speaker and wall, it's much easier to achieve perfect invisibility.

Recommended Drywall Compounds

Finish Thickness Guidelines

Sound quality and installation durability will be adversely affected if finish materials are applied too thick.

TOTAL FINISH THICKNESS FOR OPTIMAL PERFORMANCE: 1.0mm to 1.5mm (3/64" to 1/16")

MAXIMUM TOTAL FINISH THICKNESS: 3mm (1/8")

Validate finish thickness using the Sonance DG-1 depth gauge (SKU 93491).

Do not use hard-setting or stiff materials over the surface of invisible speakers, such as fast-setting drywall mud ("hot mud"), genuine Venetian plaster, stucco, metal panels, tile, etc. Use only flexible materials to finish invisible speakers.

When using flexible sheet materials such as wallpaper or veneer, ensure that the total thickness of any drywall compound, adhesives, and the finishing substrate itself does not exceed 3mm (1/8"). For wood veneer finishes, use only 20mil (0.5mm) veneer with paper backing.

1. Apply a second coat of topping compound covering the entire surface of the speaker and all adjoining surfaces.
2. Compound buildup on the active surface of the speaker should not exceed 3mm (1/8").
3. Detail the compound to minimize tool marks.
4. Allow each layer to fully cure. This can take 12-24 hours.
5. Build more coats as necessary to achieve desired finish. Each successive coat should be thinner than the last. The final coat should be a very light skim coat application.

Images show applying a second coat of topping compound and detailing to minimize tool marks.

Post-Finishing Validation

1. After the final coat is applied and has dried, use a manual pole sander or block sander on the entire wall (do not use a power sander as this could damage the surface of the speaker). Be careful not to sand down into the surface of the speaker, as this could damage the paper, making perfect blending very difficult to achieve. The wall surface should show no signs of a speaker.
2. Validate the finish thickness using the Sonance DISC system and DG-1 depth gauge (SKU 93491).
3. The final step is to once again perform an audio test. Listen to each speaker and verify that audio quality and performance have not significantly changed since your initial listening test just prior to the finishing stage. Now is the best time to fix any audible anomalies or surface imperfections.

After listening validation, your Sonance Invisible speaker installation is now complete. From this point, follow your normal method for final finishing with flexible materials such as paint, wallpaper, veneer, and so on.

Frequently Asked Questions (FAQ)

Can Invisible Series speakers be installed in the ceiling or just in walls?

Sonance IS speakers can be installed in both walls and ceilings.

Where is the best place to locate the speakers?

If installing into walls, make sure they are at least 7' (2.13m) from the floor. In ceilings, evenly space the speakers for optimal coverage, and avoid corners if possible. Contact Sonance Tech Support / Design Services for help with speaker layout planning.

What is the minimum depth requirement?

Minimum depth without enclosure = ~2.75" (70mm)
Minimum depth with enclosure = ~3.5" (90mm)

Can IS speakers be used in a plenum space?

Only models with a "T" suffix such as the IS8T are rated for plenum use (UL2043). The standard models (IS6/IS8/IS10/IS10W) are not plenum rated.

Can these speakers be installed in a T-Bar ceiling?

Theoretically yes. Consult with the manufacturer of the T-Bar ceiling in question to ensure the max load is within safe limits for the aggregate weight of the IS speakers you wish to install.

Can these be used outside?

Sonance invisible speakers are not outdoor rated and should not be used outside.

Can these be used in high heat or high humidity applications?

Invisible speakers should not be directly exposed to high heat or humidity. However, you may use finishing materials that are rated for high heat and humidity exposure, provided that they form a barrier that prevents exposure to the speakers. We highly recommend you perform a mock-up trial of the finish materials, speaker, and environment to validate the performance long-term.

What finish materials can I use with invisible speakers? Can these be covered with wallpaper or wood veneer?

Use flexible materials such as: slow-setting, lightweight drywall compounds, wallpaper, wood veneer, vinyl veneer, acrylic-based Venetian plaster. See page 14 for more details.

Are there materials that should not be used to cover the speakers?

Any material that is stiff, inflexible, or exceeds 3mm (1/8") in total thickness over the speaker diaphragm, such as tile, metal sheet, stone veneer, true Venetian plaster, stucco, etc., is not compatible with invisible speakers. The stiffness of these materials restricts movement and results in a lack of bass and muffled sound.

How much finish material can go over the speaker?

We recommend 1.0mm to 1.5mm for optimal performance. The maximum limit is 3mm (1/8").

How can I tell how much finish material is covering the speaker?

Use the Sonance DG-1 depth gauge (SKU 93491) to measure actual finish thickness covering Sonance invisible speakers.

What is the DISC system?

The Sonance DISC System provides a highly accurate method for non-destructively quantifying the thickness of a finish applied on top of a Sonance invisible speaker diaphragm. The Sonance DG-1 handheld depth gauge uses a magnetic sensor to measure the distance between the top of the finished speaker and steel discs embedded in all four corners behind the speaker diaphragm of Sonance Motion Flex Invisible Speakers.

What if I add too much finish material?

Prior to the final finishing stage (such as painting), sand down the wall or ceiling surface and measure the finish thickness using the DG-1 depth gauge. Repeat as necessary until you measure 3mm or less. We recommend 1.0mm and 1.5mm for optimal performance.

Is there a benefit to "Finish Up To" rather than "Finish Over"?

There is no practical benefit to a "Finish Up To" style finish. In fact, we recommend "Finish Over" because it typically takes less installation time and results in a more seamless, shadowless final finish. Furthermore, IS speakers are optimized for about 1.0mm to 1.5mm of finish material for best performance.

What happens if the mud or finish cracks?

Mud/finish cracks are indicative of either an improperly applied finish or invisible speakers that have been regularly overdriven. Though the integrated poly fuses mitigate against damage, they cannot protect against every type of abuse. Remember, just like traditional speakers, invisible speakers have their limit. However, the difference is when a traditional speaker fails due to over-exertion, only the speaker is damaged; whereas with invisibles, the finish can sometimes be damaged as well.

Though it is rare, if a crack occurs, Sonance will help troubleshoot the issue on a case-by-case basis. We typically start by inspecting the finish process. In most cases, the finish was applied too thick (outside of our specifications). With our new DISC system, we have the ability to prevent these types of failures before they even happen by identifying and correcting at the installation phase. This is why we highly recommend taking advantage of the DISC system during installation to prevent problems down the road.

Can I use other than Sonance DSP amplifiers?

Yes, but we highly recommend Sonance DSP amps due to the built-in DSP preset curves. Pay close attention to Sonance IS speaker rated RMS power handling and select an amplifier whose maximum RMS watts per channel closely matches or is less than the IS speaker's rated power handling. If the amplifier's power capabilities exceed those of the speakers, damage to the speaker or installed finish may occur if the speaker is overdriven. For Sonance IS woofers and subwoofers, always use a Sonance DSP amplifier to drive them.

Additional Information

I lost the screws. What is the spec or do I have to buy them from Sonance?

Use stainless steel #6 drywall screws in the appropriate length depending upon drywall/installation substrate panel thickness and local codes.

I lost the shims. How can I get more? Do I have to buy them from Sonance?

Use standard drywall shims available from your local hardware store.

Is there a protection circuit built into the speaker or do they need to be added?

Every full-range speaker in the lineup (IS6T/IS8T) has dual, self-resetting poly fuses: one dedicated to each transducer. The woofers have a single poly fuse. If a speaker is overdriven, one or both of the poly fuses will trip, and the transducers will cease to make sound, which protects both the driver and the installation surface from damage in overdrive conditions. After a few minutes, the fuses will reset, and the speakers will perform as normal. If the poly fuses are tripping, that's a sign that the speakers are being overdriven, and you should decrease the volume. If you want more volume, add additional invisible speakers to your space.

What is the warranty on IS invisible speakers, and what does the warranty cover?

The 15 Year limited warranty covers the cost to replace the speaker(s) and refinishing up to level 5 drywall finish.
