Scan-Speak 15W/8531K00

The Scan-Speak 15W/8530K-01 5.25" revelator midwoofer, well known for their sliced paper cone technology. The slices are filled with damping glue, wich dramatically reduces break-up modes in the diaphragm. In cominatiopn with Scan-Speaks low-loss linear suspension and the patented Symmetrical Drive (SD-1) it represented a brakthrough in midarange clarity and overall smooth frequency response characteristics.
