SI BM Subwoofers

Stereo Integrity goes shallow!

Big output, tiny mounting depth, tiny enclosures; that's what the BM series is all about. Using the same technology we use in our Mag series, we put the motor of the BM's inside the basket to shrink the mounting depth to a miniscule 3.5 inches on a 12" subwoofer!

Utilizing an XBL^2™ motor to give you long, linear travel, along with soft parts that include a composite flat diaphragm and inverted foam surround, the new BM series will give you unprecedented performance from a shallow mount package. Not only can you can mount them behind or underneath almost anything, but you can also use virtually any speaker grille you want to thanks in part to the inverted surround.

Why use an 8" or 10" subwoofer when you can now get more output and keep a tiny enclosure by using a 12 BM?
