you dont see amps like this everyday...

Friend had one of those crown amps. Freaking huge in person lol. One just sold for $800 on eBay last month or so.

Dang.. sounds legit

If he can format proper sentences, you should get it.

It's cool that it makes more power at 4 ohms. So, would it actually make more power as impedance rises? That would be really cool, and mind-boggling.

Someone should invent an amp that can do that, lol.

 

[trust fund baby]

It's always puzzled me how an amp can make less power, but score higher on the meter.
Someone told me it had to do with having less harmonic distortion.

Full bridge (Brazilian) amps have higher THD, and that may explain why they tend to score lower on the meter than half bridge (Korean) amps, even when producing the same power.

Thanks for weighing in!

You're just full of stupid.

And you are the all-knowing. Tell me how I am so wrong

2nd time I've seen thejeep mouthing off. Somebody needs to take you in the back alley.

How is it possible to make more power at 4 ohms than 1 ohm?

Has to do with the way the amp is designed. There are two "modes". High voltage and high current. The bpx2200 is the same way.

And yeah... shes a big bish.

His premise is actually fact based. His reasoning (and example) isn't necessarily though.

I busted the watt for watt Brazil vs. Korea thing. But there is something to the less or equal power scoring higher thing. Hence why the JBL "only" clamped 5,200w but had the same TL score as the AB 750.1 that made 1,000 more watts. That should theoretically be almost a whole dB difference.

Damping factor, yo.

Ahhh that makes more sense now. Not very often I see you on this forum man lol

o/s Soundstream amps had that feature also....on the bottom of the amps. A switch. Would be a pain in the *** to remove the amp just to switch the amp's running mode from high current to the other one. Can't recall the other "choice".

Garden City is literally 10 minutes from me. I graduated from a High School in Garden City haha. I should go pick it up

So what about damping factor in amps that gets you loud? Any links to that?

Thanks for clearing that up. It was just what someone else on CACO had told me.

Do you have any more information on damping?

There are two schools of thought about DF. One side thinks it's all important. The other thinks it's virtually useless and just a marketing thing.

The most simple way I can describe it is... it's essentially the internal resistance of the amp. And how much the amp "fights" the power returning from the sub. Higher DF = Lower resistance, less fighting. You'll hear people talk about "cone control".

The thing is... amplifiers have inherently low resistance anyway. AND the amp is just one of the components in the circuit that make up the system. The subwoofer coil being another HUGE component. Even if you had an amp with a DF of 1,000... by the time you wire it down to 1 ohm... that big ol' fancy impressive DF might be in the single digits on a Class D.

Better components have better tolerances and lower resistance. Same with build quality and the traces and all that little shit that goes into building a high quality amplifier. So higher quality amps just naturally have higher DF. They have higher DF *because* they're higher quality. They're not high quality because they have a higher DF. Does that make sense?

Have you ever heard Class A/B on subs? if you have, you know it "sounds" louder than comparable power of Class D. Or "cleaner" at least. Most will attribute this to DF. It's also the reason that wiring up to say... 2 ohms people get surprised how loud it still is even if they were running .5 before. Higher load, higher DF.

I can't go into detail about how DF specifically affects the TL score. or if A/B is actually louder than comparable Class D. But the anecdotal evidence is compelling. I reckon some (or a lot) of it may be the difference between high voltage and high current. But I have no concrete evidence one way or the other.

I can attest to this, switched my wiring from .35 to 1.4, no difference in loudness, sounds better, and worlds easier on my electrical.
