15M/4531 K00 Revelator

The Revelator midranges are 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.

Key features:

Excellent Midrange Reproduction
Sliced Cone (Controls Cone Breakups)
High Output 90dB @ 2,83V
Patented Symmetrical Drive motor design
Low-loss linear suspension
Die cast Alu Chassis vented below spider
