If I'm going to use an amp for sub, I dont see the point of testing and measuring burst outputs, and O/P power at 100Hz +.  Because, thats not how I'm going to use it... ------------- "Who am I? I'm the guy who does his job.. You must be the other guy". |

20-20K readings is what I'm usually interested in: All the rest are for those men over there with their power hungry midtops. Also, it can be for completeness - you can see the difference in power at different frequencies, and compare that to the rated power. I forgot to add, Bink's test was done with SPL stuff (TD1, runts, bdeap) and they also utilised a 2722 audio analyser thing. The ABX test was run using an ABX switch for quick comparison (like GiveorTake's idea on the other forum). ------------- Away on extended leave. |

Whats the best way to tes an amplifier's REAL power output at 20hz-20khz then? Because i'd love to see some real life figures so I knwo how much power i'd REALLY be putting into my subs. Oh by the way 1 guy said a 20amp circuit would starve a Crown MA5000, so what kind of power supply would I need to properly run a Crown XTI4000? |

| Hey andy? Does you mean a Crown XTI4000 would use 1,200watts of power and need 5 amp supply? |

only when on a test bench running sine wave 20hz to 20khz above 10 seconds.
