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-2) it represented a breakthrough in midrange clarity and overall smooth frequency response characteristics.
