Real world amp tests

[audiofanaticz]

the sad thing is the hifonics 2400 is cea 2006 compliant...

[audiofanaticz]

However, it is worth adding to be CEA2006 compliant its tested at 4ohms 14.4 volts at 1% thd.

1ohm and 2ohm tests dont matter one bit.

There is no my opinion or your opinion of rated properly is, it either does rated or it doesn't and if the only test it even comes close in is dynamic it's not doing rated.

There should be no more cea compliant bullshit either,

Let's all push for ad-1 approved labeling.

Thats a great idea. Ad-1 approved labeling is something I think we all can get behind. Well except the companies that sell amps that do rated.

And then people will start whining about the fact that those amps are too expensive...

[DubNDodge]

Well I'm going a different direction now amp wise. Butthurt? Yupp.

So I ask this question, who is going to stand up first and start rating their amps at 13.8 volts?

Yeah, i know there are the rare few that provide those ratings, but its few and far between.

I mean, I've never seen a setup that an average consumer has that can hold 14.4 and a lot of cars today are charging at 13.8. Seems like it may a requirement in the future.

I still find it funny when people dog an a amp because it wont do certified to 1%thd or to clipping they say its bad, and wont ever buy it.

Now its as long as it does dynamic its a perfectly fine amplifier....

It could be 15volts, and neither of them amps will make 2200rms in either certified test.

Just for the record, I never considered certified to be the test that determines if an amp is doing rated.

If an amp can put its rated power to subwoofers, it is doing rated. I've found dynamic is closest to what amps can do hooked to a subwoofer.

So why do higher quality amps have no problem reaching rated power on the certified test or Damn close to it?

There is no excuse for a companies product not meeting the specifications they say it meets.

If I started a company that sells let's say fire extinguishers and I claim it can put out a fire from 10 feet away but it really only works from 2 feet away is that ok to make that claim?

The fact is there needs to be more honesty in this industry and the ad-1 was designed I believe to do just that, amplifier companies can't hide the truth anymore.

Because they're way under rated.

If an amp can do rated power to a subwoofer, then it is doing rated power.

So the amp doing its rated power or more in the certified mode means it's a way underrated amp?

No it means it's rated properly, an amp should do more than its rated for in dynamic mode.

If it does exactly what it's rated for in dynamic where is your dynamic headroom coming from?

It depends on what you call rated properly.

It is just my opinion, but if an amp can do its rated power on music, then it passes my test. Others opinions may vary.

There is no my opinion or your opinion of rated properly is, it either does rated or it doesn't and if the only test it even comes close in is dynamic it's not doing rated.

There should be no more cea compliant bullshit either,

Let's all push for ad-1 approved labeling.

But then who decided a rising 40 hz sine wave decides the power of an amplifier?

Is there some law I'm unaware of that says that the AD-1 certified tests determines the power of an amplifier?

[zzSKITzz]

Crescendo ftw!! Im glad i found this thread now that its time to buy my next amp.

[DubNDodge]

What frequency do you propose to use for testing then?

I feel 40 is a happy medium.

And then people will start whining about the fact that those amps are too expensive...

Like they say if you want quality you gotta pay for it.
