Different Amplifier Qualities? Same actual RMS power but different sound?

[Ctesibius 10+ year member]

And I clearly recall a bx1500d's bench test results with a ridiculous THD level needed to create 1100 watts.

So then simply don't drive the amplifier that hard. This is what we refer to as "overrated".

If you do drive the amplifier that hard, it's not the amplifier's fault it's distorting. Regardless of it's "rating", you, the user, are driving it past it's linear limits. Point being that the amplifier was capable of low distortion when kept within it's linear operating range. Even though that range may not have been as powerful as advertised.

I love your tactful insults.

Not insults, just observations.

That is simply not true.

The amp was not always running full output. Even when running @ 500-600 watts, well below its rated output level. There was noticable distortion.

Simple fact all amps are not created equal.

Not all amps are created equal. But it's a simple fact of physics that only certain parameters, different by a certain amount, will cause audible changes.

And the vast majority of amplifiers are created equally enough that there is not a sound difference between them.

Without knowing your entire setup parameters, there is no way for me to know exactly why you heard a difference. And I serioulsy doubt that you tracked the variables close enough that even you could actually explain exactly why you heard a difference. It could simply be setup related and nothing to do specifically with the amplifiers involved.

You're right. I'm wrong. Good job:thumbsup:

Well, when you find a way to defy physics, I'll be sure to notify Nobel Prize committee //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

You're pretty much a prick aren't you. Get off your high throne and realize you have no clue what you're talking about. You think too highly of yourself.

15 posts in and you already are proving to be an arogant prick.

I have no clue ?

You're the one who doesn't understand basic physics //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

8,171 posts....yet you're proving to be an idiot.

Guess that proves post count doesn't mean a whole lot, eh?

Amps just amplify sound.

Not all amps have the same FR, but that means you can just use an EQ to even things out.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Other than that, power = power.

My kenwood excelon KAC-X811d was "CEA-Compliant Rated at 1016 watts RMS" and when directly swapped for a JL 500/1 on the same setup the JL was better.

did you set the gains correctly?

You obviously believe in the RC test. And you physics as a backing point to all of your illogical theories.

You obviously believe in the RC test.

It's not a religion. There is no "belief" system involved. It's science and physics.

Beyond that, read the link I posted earlier.

You are obviously lacking in technical knowledge and understanding, so please go back and read the link I posted earlier: http://www.elitecaraudio.com/forums/showthread.php?threadid=123226

Should clear up all of the lack of comprehension that you presently possess //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

It's only illogical to you because you're too dense to understand the science and physics behind it //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

A watt is most certainly not a watt. RC's test does not prove, or even suggest such a thing. It's very easy to disprove the hypothesis that "a watt is a watt".
Signals of many different shapes and characteristics can generate the EXACT same power. Yet, they will measure AND sound very different.

Can anyone suggest some? If I told you a lower power amp, driven HARD into clipping, can generate the EXACT same power as a higher power amp not clipping, would you "believe" me? Think they would SOUND the same? I'd be happy to show the math, indicative of a valid experiment anyone can duplicate, to "prove" it But again ... very few are interested in the notion of proof it seems

ALL AMPS SOUND THE SAME? Nobody belives this nonsense ... especially those who understand RC's hypothesis.
