Spec Sheet PDF

Good for small ported box, some suggestions below.

The 15W/8531K is a 5.5" Revelator mid/woofer. It features a non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, "Grasshopper" cast chassis with maximized air flow and resonance terminating mounting system. Less resonance in all structures, lower compression and higher linearity, faster termination of excess energy and higher sound pressure capability provide the 15W with more musical and dynamic capability than any other 5 ½" we know of. Wonderful bass in a small box!
