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 cinema 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 cinema 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.

Complete the package

Adding the Acoustimass 300 module to your SoundTouch 300 soundbar is a huge win for your home cinema experience. Even more amazing when you consider its compact size. But that's not the only compact add-on available. Virtually Invisible 300 wireless surround speakers can complete the package for a full surround sound experience. Like the Acoustimass module, they have a wireless range of 9 metres. They stand less than 10 cm high and blend nicely into your room.

Rated 5 out of 5 by from Happy Happy Happy I've had this bass module now for a couple of weeks to complement my Bose Sound Touch 300 sound bar. It does a very good job too. Although bass is omitted via the sound bar the acostimass brings it all to life with its subtle touch. Placed anywhere in the room it performs great you really hear things you thought weren't there before. The wireless connectivity is an obvious bonus, it was easy to set up and looks great. It really has brought the room to life. Genuine quality we all crave for. I think I'll be looking to add other items to it in the future as it really is listening pleasure, sounds very proffessional through the TV and my MP3 player via Bluetooth connectivity.

Rated 5 out of 5 by from Superior Subwoofer Bought this subwoofer a couple of months after buying the SoundTouch 300 which this connects with. My last entertainment system had one, and while I was very happy with just the soundbar; I did miss having the more dramatic bass sound effects when watching movies. The sound it produces is incredible - much deeper than my last Sony one, and it does give much more of a surround sound than just the bar alone. Really great for movies which have impressive sound effects. You don’t have to have this additional kit – but its a must if you want the full surround sound, in my opinion. The kit looks great in the room with the glass top - and is very easy to set up. Top end kit, but you have to pay the top end price :)

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.

What is the range of the wireless link between the SoundTouch® 300 soundbar and the Acoustimass® 300 wireless bass module?

The Acoustimass® 300 is intended for use in the same room as the SoundTouch® 300 and has a range of about 9 metres. We recommend placing the Acoustimass® 300 somewhere at the front of the room for optimum sound quality.

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?

For best sound quality, the Acoustimass® 300 should be placed on the floor against the same wall as the television and soundbar, with an electrical outlet nearby for the power cable. The module should not be placed on a shelf or table.

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.
