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 3.5 inches!
Utilizing an XBL^2™ motor to give you long, linear travel, along with our top choice soft parts that include a honeycomb 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 (thanks in part to the inverted surround). If you thought you only had the room for an 8” or 10” sub, you now have the room for a 12” sub with the new BM subwoofer.
