Bose Seismic Sound Home Theater System vs Bose Smart Ultra Soundbar System

The Bose Seismic Sound Ultimate Home Theater System (A) delivers a more immersive 5.1.2 setup with the larger Bass Module 700 and Surround Speakers 700, while the Bose Smart Ultra Dolby Atmos Soundbar Bass Module 500 Surround Sound System (B) is a simpler 3.1.2 system with a smaller subwoofer and no rear speakers. A is better for dedicated home theater rooms where deep bass and true surround are priorities. B is better for smaller spaces or buyers who want Bose's Atmos soundbar with a subwoofer but don't need rear channels. Both share the Smart Ultra Soundbar's Dolby Atmos performance and build quality, but A's added components justify the step up for movie lovers.

• Choose the Bose Seismic Sound Ultimate Home Theater System if you want a full 5.1.2 surround setup with powerful bass and rear speakers for a true cinema experience.
• Choose the Bose Smart Ultra Dolby Atmos Soundbar Bass Module 500 Surround Sound System if you prefer a compact 3.1.2 system that's easier to place and still delivers Dolby Atmos with a wireless subwoofer.
