  • Wow!

    I was always impressed with the sound of the Soundtouch 300 on its own. I've owned it for about 3 months now and it really does sound great. Finally broke down and bought the Acoustimass module. I wouldn't be able to go back now. Even my wife who generally doesn't care about things like this was pretty impressed. It can go from a nice subtle deep bass all the way to booming. You feel it in your chest. Can't recommend this highly enough.

  • Definitely a Must Have

    If you have the Bose Soundbar 300, then your going to definitely want this added to the family. Paired together produces an amazing sound. Music, movies, etc sound great. Makes me feel like I'm at the movie theater when watching movies but when I play music from my phone, you feel like your at a concert. The bass is awesome, I have a big home and you can hear everything throughout the house. Very easy to hook up and pair everything to your devices
