12M 4631 G00 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 it represented a breakthrough in midrange clarity and overall smooth frequency response characteristics.

Key features:

Excellent Midrange reproduction
Low-Loss Linear Suspension
Compact Neodymium Magnet System
Sliced Cone (Controls Cone Breakups)
High Output 89dB @ 2,83V
