Product Preparation

Amplifier Selection

The IS10-2W subwoofer requires a Sonance DSP 2-750 Amplifier to ensure high performance, protect the speaker and installation, and achieve consistent results. Sonance DSP Amplifiers are rated down to 4 ohms and are stable to 2 ohms. Never run more than two IS10-2W subwoofers in parallel on one amplifier channel.

Wire Gauge - 8 Ohm Systems

When using the product in an 8 ohm (low impedance) system, the total wire resistance should be less than 10% of the speaker impedance. The speakers are nominally 6 ohms impedance, so your total wire resistance should be no more than 0.6 ohms. Excessive wire resistance negatively affects sound quality, reducing dynamics and bass definition, and potentially attenuating high frequencies. Amplifier power is also wasted in the wire, reducing maximum output. Refer to the chart below for appropriate wire gauge selection.

Speaker Locations

Invisible Series full-range speaker models (IS6, IS8, IS10) have a 170-degree hemispherical dispersion pattern. The IS10-2W subwoofer has a 180-degree hemispherical dispersion pattern, allowing for a wide range of applications and installation locations.

The IS10-2W should only be wall mounted. Ensure the speaker is not covered by cabinetry, draperies, art, crown molding, or anything that could cover or puncture it. Ensure the back of the speaker has clearance and is not adjacent to electrical, HVAC, pipes, fire sprinklers, or other building systems that could violate local codes or adversely affect sound quality.

Installation Accessories

The use of space savers and preconstruction zip rings is recommended for better coordination and results. Space savers reserve precise dimensions and locations during construction, protecting speaker wire. They allow delaying speaker installation until just before the finishing stage, reducing risk of damage or theft. For large quantities, preconstruction zip ring brackets can guide accurate drywall cutouts using a drywall zip tool. These can be used with or without space savers when drywall is laid directly over speaker locations. Contact Sonance for bulk pricing on zip rings.

Space Saver Part Numbers

New Construction

The subwoofer occupies two stud bays in a standard 16" on center framed wall. It should be boxed out like a window, with structural loads transferred from the top plate to the bottom plate. Follow these best practices:

1. Use the speaker template to create the proper space for the subwoofer.
2. Add two scabs to the header. The gap between them provides space for speaker wire strain relief. If wire comes from below, add scabs to the sill.
3. Use construction adhesive to bond all double studs together to prevent creaking and buzzing.
4. Use screws instead of nails for the subwoofer location, as nails can loosen over time.

Installing the Speaker

• Do not remove the back box of the subwoofer.
• Install the speaker with the included stainless-steel screws.
• Do not add a screw at the center location above the speaker wire strain relief, as wire damage can occur.

Project Management & Finishing Preparation

Listening Test

Key tips for testing the subwoofer:

• Allow construction adhesive to dry before energizing the subwoofer.
• During listening tests prior to mudding, listen for buzzes, squeaks, and chuffing.
• Fix noise problems before drywall mud is applied.
• Let the subwoofer play at a moderate to high level for 30 minutes to discover possible noises.

Drywall

Apply construction adhesive to the front and back of studs above, below, and on the sides of the subwoofer cutout. Drywall can loosen over time, creating buzzing and slapping noises. Use screws instead of nails, placed every four inches around the subwoofer opening and every six inches for side stud bays. Avoid drywall joints at the IS10-2W location; use studs to support any nearby drywall joints. Apply construction adhesive to the bottom plate to prevent air leaks and chuffing sounds.

Finish Materials

Prior to speaker installation, verify that the topping compound and final finish are flexible materials (slow-setting drywall mud/topping compound, wallpaper, acrylic-based Venetian plaster, thin wood veneer) and will not exceed 1/16" (1.5mm) in total thickness. The recommended target for optimal performance is between 3/64"-1/16" (1.0-1.5mm) of topping compound. Sound quality and installation durability are adversely affected if too much topping compound is applied. For wood veneer finishes, use only 20mil (0.5mm) veneer with paper backing. Do not use hard-setting or stiff materials like fast-setting drywall mud ("hot mud"), genuine Venetian plaster, stucco, metal panels, or tile, as they restrict movement and result in muffled sound.

Project Management

Precise installation requires project management and close coordination with drywall and finish trades, and the General Contractor. Follow these best practices to prevent unmet expectations and rework:

• Schedule a walk-through with the client, General Contractor, and finish manager after speakers are installed but before finishing. Listen to each speaker to identify anomalies.
• Obtain sign-offs on audio performance from all parties. Use a checklist for this.
• Review installation steps with the finish manager, emphasizing minimal flexible material coverage for invisibility, typically 3/64"-1/16" (1.0-1.5mm), with a maximum of 1/6" (1.5mm) total finish thickness.
• Use the Sonance DISC system and DG-1 depth gauge (SKU 93491) to validate finish thickness.
• After finish material dries, perform another listening check. If performance differs from the pre-finishing test, the finish thickness likely exceeds the maximum and needs correction.
• Remember, it is too late to correct excess finish material after flooring and furniture are installed.

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

It also highlights the need to place studs behind any drywall joints and to avoid joints next to the speaker. A cross-section view shows the speaker within the framing, attached to drywall with screws, and notes the use of construction adhesive.

Pre-Finishing Testing Guidelines

Once a finish is applied to an invisible speaker, it will be too late to fix any audio connection or installation problems. Follow these testing guidelines before proceeding to the finishing stage.

Installation Fit Test

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

Audio Test

Connect a high-quality audio source and Sonance DSP-2-750 amplifier (in 8 ohm mode) to the installed IS10-2W subwoofer. Ensure the correct EQ preset is applied using SonArc software. Adjust output for moderate volume. Play music to check for overall fidelity and listen for buzzes or rattles. A slow tone sweep from 20Hz to 500Hz for subwoofers and 20Hz to 5kHz for full-range speakers can help pinpoint buzzing from loose studs, screws, drywall, cable vibration, or rattling components. Fix any installation or audio issues before moving to the next steps. Active project management practices (pages 5-6) are highly recommended.

IS10-2W Finish Thickness Guidelines

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

Total Finish Thickness for Optimal Performance of IS10-2W Subwoofer:

Apply the absolute minimum finish necessary to make the speaker totally invisible. Typically 3/64" (1mm) or less.

Maximum Total Finish Thickness for IS10-2W Subwoofer:

1/16" (1.5mm)

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 like lightweight drywall topping compound.

When using flexible sheet materials like wallpaper or veneer, ensure the total thickness of any drywall compound, adhesives, and the finishing substrate does not exceed 1/16" (1.5mm). For wood veneer finishes, use only 20mil (0.5mm) veneer with paper backing.

Finishing Instructions

NOTE: Drywall finishes vary in smoothness. For invisible speakers, a level four finish (feathered and sanded seams) is recommended. For best results, a level five finish (skim-coated and sanded plane) is advised 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, overlapping slightly.
5. Do not tape over the raised portion of the speaker.
6. Allow hot mud to fully cure and harden.

Steps 1-6 illustrate filling gaps, feathering edges, applying mesh tape, and allowing the compound to cure.

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 (12-24 hours).
10. Apply a second coat of topping compound covering the entire surface of the speaker and all adjoining surfaces.

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

Recommended Drywall Compounds

IMPORTANT: For a perfectly flat finish, you may proceed to priming and painting ("Finish Up To"). Multiple paint layers are recommended for a shadow-less blend. A "Finish Over" process, with an additional skim coat over the entire speaker and wall, is highly recommended for a more seamless, shadowless finish and typically takes less time.

Steps 7-10 illustrate applying slow-setting compound, feathering, curing, and applying a second coat.

11. Compound buildup on the active surface of the speaker should not exceed 1/16" (1.5mm).
12. Detail the compound to minimize tool marks.
13. Allow each layer to fully cure (12-24 hours).
14. Build more coats as necessary to achieve the desired finish. Each successive coat should be thinner than the last; the final coat should be a very light skim coat application.
15. After the final coat is applied and has dried, use a manual pole sander or block sander on the entire wall. Avoid power sanders, which can damage the speaker surface. Be careful not to sand into the speaker surface, as this can damage the paper and make blending difficult. The wall surface should show no signs of a speaker.
16. Validate the finish thickness using the Sonance DISC system and DG-1 depth gauge (SKU 93491).
17. The final step is to perform another audio test. Listen to each speaker and verify that audio quality and performance have not significantly changed since the initial listening test just prior to the finishing stage. This is the time to fix any audible anomalies or surface imperfections.

After listening validation, your Sonance Invisible speaker installation is complete. Proceed with your normal method for final finishing using flexible materials like paint, wallpaper, or veneer.

Steps 11-17 illustrate compound buildup, detailing, curing, sanding, thickness validation, and the final audio test.

IS10-2W Specifications

Frequently Asked Questions

The IS10-2W should not be mounted in T-Bar ceilings. Ceiling placement could lead to long-term sagging of the diaphragm.

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 rated for high heat and humidity exposure, provided they form a barrier preventing exposure to the speakers. A mock-up trial of the finish materials, speaker, and environment is highly recommended to validate long-term performance.

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.

ARE THERE MATERIALS THAT SHOULD NOT BE USED TO COVER THE SPEAKERS? Any material that is stiff, inflexible, or exceeds 1/16" (1.5mm) in total thickness over the speaker diaphragm, such as tile, metal sheet, stone veneer, true Venetian plaster, stucco, etc., is not compatible. The stiffness of these materials restricts movement and results in 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 1/16" (1.5mm).

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 finish thickness. The Sonance DG-1 handheld depth gauge uses a magnetic sensor to measure the distance between the finished speaker surface and steel discs embedded in the speaker diaphragm.

WHAT IF I ADD TOO MUCH FINISH MATERIAL? Prior to the final finishing stage (e.g., 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 1.5mm 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. We recommend "Finish Over" because it typically takes less installation time and results in a more seamless, shadowless final finish. The IS10-2W is optimized for about 1.0mm to 1.5mm of finish material for best performance.

WHAT HAPPENS IF THE MUD OR FINISH CRACKS? Cracks indicate an improperly applied finish or speakers that have been regularly overdriven. Integrated poly fuses mitigate damage but cannot protect against all abuse. Like traditional speakers, invisible speakers have limits. If a traditional speaker fails, only the speaker is damaged; with invisibles, the finish can also be damaged. If cracks occur, Sonance can help troubleshoot. Often, the finish was applied too thick. The DISC system helps prevent these failures by identifying and correcting issues during installation.

CAN I USE OTHER THAN SONANCE DSP AMPLIFIERS? To achieve specified performance, the IS10-2W must be used with the DSP2-750 amplifier and the correct EQ preset. Using other amplifiers may compromise performance and long-term reliability.

ARE THESE SUITABLE FOR SURROUND SOUND? The IS10-2W is designed specifically for use in surround sound and large space distributed audio systems.

WHAT'S THE BENEFIT OF SOUND-ISOLATING ENCLOSURES? The integral IS10-2W sound-isolating enclosure provides approximately 20dB of broadband noise reduction, greatly reducing sound transference into adjacent spaces.

IS THE IS10-2W SOUND-ISOLATING ENCLOSURE UL RATED? No.

I LOST THE SCREWS. WHAT IS THE SPEC OR DO I HAVE TO BUY THEM FROM SONANCE? Use stainless steel #6 drywall screws of appropriate length depending on 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? The IS10-2W subwoofer has a single poly fuse. If a speaker is overdriven, the fuse(s) will trip, ceasing sound output to protect the driver and installation surface. After a few minutes, the fuses reset. If fuses trip repeatedly, it indicates the speakers are being overdriven; decrease volume or add more speakers for more volume.

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.
