Welcome to Stereo Integrity

about us image Here at SI, we have dedicated the past 3 years to developing our current product - the BM mkIII series shallow subwoofer. We spent countless hours using FEA to aid us in the development of the mkIII series. Lots of tooling and testing later, the BM mkIII subwoofer is finally ready.

Testimonials

"Listening to rock it provides the low end without being noticeable and keeps the sound up front really well. I even turned the sub off on occasion just to realize how big a part of the music it was actually playing, because honestly it sounded like my midbasses were doing the work. On rap/pop it has a good amount of output but still stays up front for the most part."
