Scan-speak 15W/8530K-01 5.5" Revelator Slit Paper Cone Midwoofer- 148mm - 8 ohm
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-1) it represented a breakthrough in midrange clarity and overall smooth frequency response characteristics.
High Qts version, good for sealed or free air. The Revelator woofers and subwoofers feature very rigid cones in paper or aluminium that operate as a piston over a wide frequency range, in combination with Scan-Speak's low-loss linear suspension and the patented Symmetrical Drive (SD-1) results in very low distortion and a smooth and well behaved frequency response as well as perfect transient reproduction.
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 allow the 15W more musical and dynamic capability than any other 5 ½" we know of. Wonderful bass in a small box!
