Product details
The Scan-speak 18W/8531G-00 is a 7″ 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. The 18W/8531G should have an F3 of about 55Hz sealed and can get down to 33Hz vented.
