SCAN SPEAK 18M/4631T00 6.5" Bass-midwoofer
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.
Highlights:
Paper cone technology
Coated Foam Surround
Sliced Cone (Control Cone Breakups)
