Setup
Speaker Placement
Strategic placement of your speakers is crucial for optimal sound coverage in outdoor environments. Consider the listening area and potential obstacles.
- Pendant Speakers: Distribute the four pendant speakers evenly around the perimeter of your desired listening area. They can be mounted on stakes (included) or hung from eaves or pergolas. Aim for a triangular or rectangular layout for balanced sound.
- Subwoofer: The in-ground subwoofer should be placed centrally within the listening area or near the main seating area to maximize bass impact. It is designed to be partially buried, with only the mushroom-shaped vent visible above ground.

Wiring the Pendant Speakers (70V/8 Ohm)
The Forza 5 pendant speakers are compatible with both 70V distributed audio systems and standard 8-ohm amplifiers. Select the appropriate wiring method for your setup.
- 70V Systems: For commercial or large residential installations, connect the speaker wires to the appropriate 70V tap setting on the speaker's rear terminal. Ensure your amplifier is 70V compatible.
- 8 Ohm Systems: For standard home audio setups, connect the speaker wires to the 8-ohm terminal. Ensure your amplifier can handle an 8-ohm load.
- Wire Gauge: Use appropriate gauge speaker wire for the length of your runs to minimize signal loss. Consult a wire gauge chart if unsure.

Subwoofer Installation
The XSUB12 subwoofer is designed for in-ground installation to blend seamlessly with your landscape while delivering powerful bass.
- Digging the Trench: Dig a trench for the subwoofer body, ensuring the mushroom-shaped vent will be above ground level. The trench should allow for proper drainage.
- Wiring: Connect the subwoofer to your amplifier's subwoofer output or a dedicated subwoofer amplifier. Ensure waterproof connections are made.
- Backfilling: Carefully backfill the trench around the subwoofer, ensuring it is stable and level. Avoid covering the vent.

Operating Your System
Once installed and wired, operating your OSD Audio outdoor system is straightforward:
- Power On: Turn on your amplifier or audio receiver.
- Source Selection: Select your desired audio source (e.g., streaming device, media player).
- Volume Control: Gradually increase the volume to a comfortable listening level.
- Bass Adjustment: If your amplifier has a subwoofer level control, adjust it to blend the bass seamlessly with the pendant speakers.
Maintenance
To ensure the longevity and optimal performance of your outdoor speaker system, follow these maintenance guidelines:
- Cleaning: Periodically wipe down the exterior of the pendant speakers and the visible part of the subwoofer with a damp cloth to remove dirt and debris. Avoid harsh chemicals.
- Drainage: Ensure the area around the in-ground subwoofer remains clear of standing water. Check for proper drainage, especially after heavy rain.
- Cable Inspection: Annually inspect all exposed speaker cables for signs of wear, damage, or rodent activity. Repair or replace damaged cables promptly.
- Winterization (Optional): While designed for all-weather use, in regions with extreme winter conditions, you may consider covering the pendant speakers or temporarily storing them indoors if easily removable. The in-ground subwoofer is designed to remain in place.
