How to use

Position the subwoofer on a stable surface near your HT-A9 or HT-A7000 system and follow the Sony wireless pairing procedure described in the system manual to establish a connection.

Adjust volume and crossover settings via the main system’s sound settings to balance bass level with other speakers in the room.

Recommendations

For best low-frequency performance, place the subwoofer near a wall or corner to increase bass reinforcement, but avoid placing it directly against fragile surfaces. Because this unit is sold with damaged packaging, inspect the product on delivery for cosmetic or transport-related issues and retain the 12-month warranty documentation for service if needed.
