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.

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
