Bigg Boy Posted December 30, 2009 Report Share Posted December 30, 2009 Thd under a certain percentage is very very hard to hear. When you use a spectrum analyzer you can see the thd rising long before you will hear it.

Ray Posted December 30, 2009 Report Share Posted December 30, 2009 no james you can see "distortion". But T.H.D is a collective of ALL harmonics in the signal path. Hence "total" You "see" disturbances in the signal. ie: distortion. That is all. To most in the know, THD is a bullshit #/ measurement.

Bigg Boy Posted December 30, 2009 Report Share Posted December 30, 2009 I set it up the same way I was taught to set things up in the studio environment. To be honest wouldn't be surprised if what I was taught wasn't 100% the truth, but then again, I have never had problems using this method. Okay lets get this thread back on topic, I apologize for kinda thread jackin Dodge Magnum with custom 300c front end, laid out on air bags *4) 12" Cadence Daytona walled *1) AudioQue 20k *270a DC Power Alt (Dual coming soon) Link to comment Share on other sites More sharing options...

The Performer Posted December 31, 2009 Report Share Posted December 31, 2009 I would go out on a limb to say that the 87 doesn't clip at all that I can tell. My crossover is set at low:0 high:-10 mid:-12. And yes, after about 26 the volume level is about the same. I stop at 24 as my max. What are you having a problem with on your 9887? CERTIFIED BITCHES!!! Not being new at something doesn't mean anything. Just because a prostitute isn't new at what she does, doesn't change the fact that she still 'sucks' Click to see my build!
