Acoustimass 300 wireless bass module




Thunderous bass. Wireless connectivity.

Love your new SoundTouch soundbar but want to kick the performance up a notch? Add the Acoustimass 300 wireless bass module—it’s the difference between hearing bass and feeling thunder. Designed exclusively for the SoundTouch 300 soundbar, it’s the best Acoustimass module we’ve ever designed for any of our home theater systems. In fact, it’s the best performance you can get for a subwoofer this size. It connects wirelessly to the soundbar and provides a more immersive experience for everything you listen to or watch.


With its premium glass-top finish, the Acoustimass 300 wireless module offers a sophisticated look you won’t find in typical subwoofers or home theater equipment. Of course, this isn’t typical equipment. This newly designed subwoofer delivers a dynamic range of bass from a powerful driver and generously sized port with QuietPort technology that virtually eliminates distortion.

Like the Acoustimass module, they have a wireless range of 30 feet. They stand less than 4" high and blend nicely into your room.

Rated 5 out of 5 by from This is the best ever Acoustimass I have ever seen This is the best ever Acoustimass I have ever seen. I just could not think anything negative about this product! Very easy and quick setup No wires around It is the heaviest module! 30lb..which is producing a stable bass effect with out any vibrations Very much suitable for apartment living as it did not pass on the vibration to other apt even with higher volume as it is well blended with adaptiq design.. And the sound quality is just amazing and rich!!! Looks so good, decorative.. We don't have to worry about kids throwing stuffs in to woofer holes.. this module is well designed to avoid that... This is greatest compliment to the sound bar 300...!!!

Rated 5 out of 5 by from Took the vibration out of the Soundbar Began my experience with the SoundTouch 300 which was amazing! After a couple of weeks I began to notice what I thought was a blown speaker with vibration sounds. Then something fell off my mantle, which is where I chose to put the soundbar. I realized that it was due to the fact that the soundbar has the ability to put out pretty good bass. When I obtained the Acoustimass 300 it made a huge difference! The bass tones were even more richer than the stand-alone. Set up was incredibly easy, but access to complete instructions on line is necessary to tell you how to tell if the sub paired with the soundbar. Access to the online manual was great because I learned many more things about how to use the Acoustimass. For instance, when watching a news show, sometimes voices are not the clearest in a room with other noise such as someone washing dishes. There is a button on the remote that allows you to back off ambient noise in the program and allow focus on voices. It definitely helps my husband whose hearing isn't always the best be able to hear the news stories better. However, when watching a movie or other TV shows, just push the button and the deep tones come back. The amount of bass can also be adjusted from the remote rather than having to dig behind the module to make the adjustment. One thing that I'm not completely satisfied with is the buttons on the remote. I can usually memorize where buttons are on remotes, but because the buttons barely stand above the surface, it is sometimes difficult to decide which button my finger is on. Some small bumps on certain buttons could help with that. However, I love the functionality of the remote as it operates everything, flawlessly. Compared to other sound systems I have owned Bose continues to improve something every time. Ease of use with wireless & bluetooth capability and operation from the remote is where I find a huge improvement.

Do I need to rerun the ADAPTiQ audio calibration system when the Acoustimass 300 wireless bass module is added to the SoundTouch 300 soundbar?

Yes, we strongly recommend that you rerun ADAPTiQ if you add the Acoustimass 300 to your system.

Can the Acoustimass 300 wireless bass module be wired?

Yes. If for some reason the customer prefers a wired connection, then the Acoustimass 300 bass module and the SoundTouch 300 soundbar can be hardwired together using a standard 3.5 mm audio cable. Contact your local Bose customer service provider or purchase this standard cable at any electronics store.

What placement guidelines should be considered to ensure optimal audio performance of the Acoustimass 300 wireless bass module?

Can I add the Acoustimass 300 wireless bass module to other one-piece SoundTouch speakers, such as the SoundTouch 10 wireless music system?

No. The Acoustimass 300 can only be added to the SoundTouch 300 soundbar.
