Spec Sheet PDF

The Revelator midrange and midwoofers, both well known for their sliced paper cone technology. The slices are filled with damping glue, which dramatically reduces break-up modes in the diaphragm. In combination with Scan-Speaks Low-loss linear suspension and the patented Symmetrical drive (SD-2) it represented a breakthrough in midrange clarity and overall smooth frequency response characteristics. 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. Great in 1 cf3 vented, see below.
