Description

Our BP-SD18 is the smaller brother of the BP-SD21. It is a passive single 18″ subwoofer with unique design. Similar in appearance and design, being the same height and depth so it can be used together with the 21″ Sub Engine. A beast of a box, it has the low frequency output to match its eye-catching appearance. The BP-SD18 boasts near double 18″ output from a box one half the size of one of a double 18″ box.
