"These things absolutely sound fantastic…and they slam. We put them on a pair of [high quality passive loudspeakers] that we have had on at least a half dozen other amplifiers and pairs of amplifiers and never really liked the results. Even with the amps cold out of the box…this is the best these speakers have ever sounded...buy 2 and bridge them!"

Ron Lennox, Definitive Electronics
