MIDWOOFER 15W/4531G00
The Revelator midrange and midwoofers, both well known for their sliced paper cone
technology. The slices are filled with damping glue, which dramatically reduces breakup 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:
· Patented Symmetrical Drive motor design
· Low-Loss linear suspension
· Die cast Alu Chassis vented below spider
· Sliced Cone (Controls Cone Breakups)
· Low Damping SBR Rubber Surround
· Large Ferrite Magnet System
