You don't want to just hear the bass, you want to feel the thunder. Designed as a complement to the Bose sound bar 700, the Bose bass module 700 delivers rich, resounding bass in a compact wireless subwoofer, so you can feel the full impact in every thrilling moment of your music, movies, and TV. With its premium glass-top finish, the Bose bass module 700 offers elegance you won't find in typical subwoofers or home theater equipment. But the real beauty Lies beneath the exterior. This wireless subwoofer delivers a dynamic range of resounding low notes from a powerful driver and generously sized port. You can actually feel the crushing footsteps of a t-rex on the screen, or a heart-pumping, beat-stomping chorus in your favorite song. Don't be afraid to turn up the volume, either; quiet port technology virtually eliminates distortion without sacrificing clarity. Want to kick up the performance of your sound bar and bass module a little bit more? just add the Bose surround speakers to the Bose sound bar 700 and bass module for full-on surround sound.
