Gene Cerwinsky (Cerwin-Vega) produced one of the first commercially available high power (then 180-350 watts) in the early seventies. The amplifier an 18" driver and horn cabinet were the bottom behind the film "Earthquake." Theaters premiering the film were required to bolster their sound systems with the Ceriwn-Vega low frequency equipment and theaters never looked back.
The driver found its way into the legendary 200 watt acoustic 360/361 folded horn Bass Amplifier which throws a twenty-five foot low E wavelength.
Cerwin-Vega amplifiers were quickly followed by Ampzilla, Phase Linear, and Crown which were quit different in design from one another. For all those who complain about class D, in those days of early solid state the incredibly edgy presentation was easily overlooked for the high power output. Within months the controversy between tube watts vs solid state began and life as we know it was born.
Personally, I bypassed the volume pots, replaced the capacitors, a few resistors, and most of the hook up wire in a Cerwin-Vega A1800 and the results were quite dramatic and used the amp well into the 80's to power the ever less efficient speakers being offered.
