[QUOTE="Greg Cameron, post: 8350, member: 42"] To those in the know about Crest Audio Pro series amps, can you answer me a question? I'm comparing spec sheets (always a dangerous thing) between the older Crest 7001 and the newer Crest 7200 series power amps. They're suppose to be comparable amps. Here's what's bothering me. Using the full power output (4 ohm bridge) spec for comparison at 1kHz, the 7001 is listed for 1700 watts at <.02%THD+N. The 7200 lists output at 3300 watts at <.1%THD+N. or about double. However, the [i]rms voltage swing[/i] for the 7001 is listed higher at 83V vs 75v for the 7200. Does pushing the 7200 into slightly more distortion and measuring truly equate to double the power? I thought you really had to be hard clipping to get that kind of power increase at the load. Something seems fishy with the numbers, they don't add up for me unless I'm missing something (am I?). This doubling of output power ratings appears to be across the board with the Pro x001 series vs. the newer Pro 200 series... [/QUOTE]
