The Bose Soundbar 500 is a great start, but if you??™re looking to amp up the performance, just add the Bose Bass Module 500. Designed for the Bose Soundbar 500, the Bose Bass Module 500 takes your music, movies and more to a whole new level. It??™s thunderous bass in a compact, 10-inch cube with wireless connectivity making it easy to hide, but even easier to hear. Who says you need a big box for big bass? Not us.
