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 moduleÔÇöit'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.

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 Fantastic Bass, amazing looks! I first got a Soundtouch 300 and as much as I loved it I was waiting for the opportunity to get the Acoustimass. Firstly, I was impressed when I received it. The size and weight of the package immediately made me think that I was about to unveil something amazing and oh my I could not have been more right! It is sleek and solidly built and it just looks great. And once connected it gives a depth to the sound and compliments perfectly the Soundbar, making watching movies a complete different experience! I couldn't be happier with the results. The amount of bass can be turned up and down and this is something that took me a while to figure out, but now I have it turned to the max and it is just beautiful, watching films and listening to music in my living room has gone to a new different level. Ive have had it for over two weeks and it has always connected without any problems to my Soundtouch. The simplicity and ease to use and control, its unbelievable design and superb sound make this another amazing Bose product that I cant recommend enough!

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.
