I helped build, install the sound and then DJ'd a dance club years back. We only played 45 RPM long play vinyl. Its when I was first introduced to high end masters and tracks before they were cut down for radio etc. Some of the long play 45's sounded amazing. We fitted the club with Crown amps and all JBL. The bass was amazing. We used 6, 18"
front loaded JBL, mids and 2445 highs. Wow was how it all sounded. The specs on them were the best of all the amps we looked at. I later took part of that system on the road and started a techno duo. We used all JBL, all front loaded but used Carver, Yamaha and Bryston. Nothing compared to the Crowns for bass.
