How to Open a Bose Acoustimass Subwoofer

Updated February 21, 2019

The Acoustimass module from sound system manufacturer Bose is the subwoofer portion of a system with satellite speakers. It connects to a receiver and produces the low-end frequencies that can be felt as well as heard. The Acoustimass subwoofer is a large, polymer box that is placed on the floor adjacent to the television set, at least three feet away. Depending on the specifics of the sound system, the Acoustimass weighs at least 9.07 Kilogram. Bose produces several versions of the Acoustimass to correspond with various-sized sound systems, and does not recommend opening any of them on your own.

  3. Unscrew the speakers from their mounts, and pull them out. Depending on your Acoustimass module model, you may now be able to see inside the box.

    Bose does not recommend trying to open the Acoustimass on your own. Doing so can damage the module's components and/or void your warranty. Bose recommends taking your module to a licensed Bose technician in the event of a problem with the Acoustimass speaker.
