The Scan-speak 15W/4531G-01 is a 5 ½ Revelator mid/woofer. It features a slit-paper uncoated non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, Grasshopper cast chassis with maximized air flow, glass fiber voice coil former and resonance terminating mounting system. The 15W/4531G provides a more extended frequency response than its brothers, but still fantastic bass down to the mid 50s in a vented enclosure. This version is only available in 4 ohm.
