Our newest and largest coned driver, the RL-p18 is downright astounding for home theater use, particularly in large-low-tuned vented enclosures or infinite baffle alignments. Taking into account the solid stats on the Premium Series home page, the RL-p18's beefed up 215 ounce magnet structure, dual 8.5" spiders and upgraded tall NBR rubber surround make way for absolutely insane low-frequency SPL capability!
