Sub Amp

[AcuDefTechGuy]

It depends on which Crown

The XLS Drive Cores are virtually silent. The Behringer will require mediation of some sort. I'm in process of moving the amplification stack to the garage so it won't matter in my case.

You should be able to check out the Crown and Behringer units at Guitar Center. They have a 30 day no hassle return policy.

Thanks. I think I will go by the Guitar Center.

Is an amp like the Behringer NU6000 the real deal? I know class D is supposed to deliver more power for less money,

Not necessarily. Class D circuitry can be just as, or more expensive than Class A/B. Of course the heavy duty heatsinking is a cost in class AB and Class A that you can avoid, but that's really about it.

Will I ever need more than 2400 Watts?

For a long throw 18 in a small sealed box with an fs over 20hz ? That little power probably won't even be enough to hit xmax!

Is 6-9 cubes small for an 18 inch?

That would be CHT / Craig Chase / AKA CraigSub

You got the easy one. But can you guess the hard one?

(I got my information about the designer/sourcing of these amps from the "hard" source.)

Is Behringer fan noise louder than Crown?

How loud are any of these fan noise anyway?

You won't hear the Crown fan.

The behringer fan, if it's anything like my stock tapco fans, will sound like you're vacuuming the house. I had to swap the stock fans with these:

Noctua NF-R8 80MM Ultra Quiet Cooling Fan 800-1800RPM 26-53M3/H 7-17DBA Molex - Noctua - NF-R8-1800

Which, even then, can still be heard at very low levels. If I were doing it over (and I might), I'd get the Crown.

But isn't 2400 watts the Max power output for 20A circuits?

Not exactly.

Basically, a 20A circuit breaker will pass that kind of power for a while (IE 15 minutes) before it trips. Since audio content is more dynamic than it is continuous, you might be able to get a lot more power than the "Rated limit".

The key is this:

a 15A circuit will probably use 14awg
a 20A circuit should use 12 awg

so the larger circuit will have more wire/heatsinking.

Ya, it's JD at Peavey. BTW keep your eye out for a MA400 prototype power amp from the 90's. Instead of the the production IGBT transistors it had MOSFets. He would like it back after it was stolen out of his vehicle in Jersey.

JD Bennett at Peavey wasn't my other source on the SA1000's output. To my knowledge, Peavey never sold a version of it with a Peavey logo on the front.

He was, however, the above-mentioned IPR-series lead designer who mentioned that "continuous" and "burst" for his IPR's are basically the same thing.

Didn't know which you were referring too.
