The reverberating companion to the SoundTouch 300 Soundbar is this Acoustimas 300 Wireless Bass Module for even more electrifying listening enjoyment. It weighs 30 pounds and is, 12” W x 12” L x 15” H, containing a 10” woofer. For its compact size it packs a lot of audio engineering by Bose. It easily pairs, wirelessly, to the 300 Soundbar using the remote, included with the soundbar. The intensity level of the bass can also be increased or decreased by using the remote. At the Bose 'Support Center' you can download the Owners Guide for the Acoustimas 300 Wireless Bass Module. It is very comprehensive, detailed and includes many illustrations. If you have any issues you may find the solutions there, or, in the Owners' Community Blog.
I consider myself an 'audiophile' with over 50 years of amateur experience in building Hi-Fidelity, stereo systems. This is my summary of this fantastic soundbar and subwoofer pairing. Keep in mind the Bose 300 Bass Module is built and configured specifically to operate with the SoundTouch 300 Soundbar. It is not a subwoofer component that you can use in any other system. The Acoustimas 300 is a wireless, powered subwoofer, which has its own built-in amplifier. This powered amp takes the load away from the smaller speakers in the soundbar when low frequency sound is reproduced in the bass module. Because bass demands more power at low frequencies, 20Hz to 80Hz, and less power as the frequency increases. The smaller speakers in the soundbar start to take over around 90Hz using Bose' PhaseGuide technology, which makes you feel like you are hearing sounds from areas of your room where there are no speakers. In my opinion one of the best characteristics of a good subwoofer is that it doesn't emit 'boomy' and late sounds out of sync with the satellite speakers (soundbar) at low frequency. Because of Bose Quiet Port technology this subwoofer module produces clear, vibrant, omnidirectional bass that you can't even tell where the low frequency sound is coming from. It surrounds your whole room, especially, after you calibrate both the soundbar and bass module using the proprietary, ADAPTIQ Calibration process. YooHoo!
This is the primary reason why the Acoustimas 300 Bass Module compliments the soundbar to provide you with richer, more vibrant, realistic sounds that the soundbar alone can duplicate. The Bose Acoustimas 300 accomplishes that with success. And the construction of the bass module with its unique glass top probably has a lot to do with the amazing, crisp and deep, distortion free bass.
This matched system was designed for you to conveniently connect to the ARC, HDMI port from your TV. It takes no power from your TV just the acoustical pass through signal. The Bose 300 Soundbar and Bass Module do not require connection to an A/V Receiver or Amplifier. However, you can connect the Bose 300 Soundbar to an A/V Receiver if you have the appropriate connections. I connected my A/V Receiver to the 300 Soundbar and was floored by the dynamic, awesome, sound. Since the bass module does not have an LFE port it cannot be connected to the A/V Receiver, but still operated through the soundbar. Although I have a graphic equalizer in my receiver, I did not need to use it. Instead I tried enhancing the sound through the various audio presets like concert hall, arena, movie, theater, gaming, etc. Unbelievable. WooHoo!
The Acoustimas 300 does have a power saving mode so you can safely keep the unit plugged in all the time to an A/C outlet. It powers itself 'down' when not receiving a signal from the soundbar.
While on the subject of 'Power' - I want to bring up surge protection for your home theater, TV, Bose SoundTouch 300 Soundbar and Acoustimas 300, and all other associated electronics. Protect your expensive, electronic equipment with appropriate surge protection. Better protectors exceed peak ratings of 1000 joules and 40,000 amperes. The higher the rating in joules, and the lower the let-through voltage, the better you are protecting your devices. The 300 soundbar, 300 bass module, subwoofer, and two optional, wireless speakers can all be protected using surge strips or a space-saving surge protector that sits over an existing wall outlet. It is too risky to go without it. If you take anything away from my review – please, consider adequate surge protection for your audio and electronic equipment.
If you already have the SoundTouch 300 Soundbar, then the Acoustimas 300 Wireless Bass Module by now is a 'Must-Have'. I highly recommend the Acoustimas 300 Wireless Bass Module because of its significant, audio engineering features. No matter where you place this unit in your room you will not be able to tell where the dynamic sounds are coming from. It won't rattle your windows, or break glass, but it will provide you with quality, distortion free, acoustically matched music enjoyment. By adding the Invisible 300 wireless surround speakers you can also create a true 5.1 channel system of auditory sensation.
