Would you run a class a/b amplifier on you woofer/s?

IIRC All Profile California mono sub amplifiers and a/b, stable only to 2ohms.

did u just say that a/b amps can only be ran down to 2 ohms or did i missunderstand you?

I said that the profile california a/b mono sub amps can only be ran down to 2 ohms.

So usually a 800 watt class A/B amp for subs from a 800 watt class D will not result in a loss of bass?

And the debate question has been raised.

I personally think there is a difference in SQ.

Me too

Would you run a claas a/b amplifier on you woofer or woofers? Would it take a toll on your woofer? Would it be ok?

Class A/B amps wouldn't wear out your subs any more than class D's would.

Class D's basically trade THD for efficiency, and vice versa for A/B.

Class a/b amps do seem to sound a good bit better than class d. As said you trade effeciency for some sq. Also the a/b runs a lot hotter, which may be a problem for some people.

I like the A/b amps better every time I try a class D I switch back to A/B. The experts say that class D tech is coming up in SQ all the time but i just don't hear it. I need a blind test with drop in replacement.

As I prefer SQ to SPL I always use class A/B s rather than a Monoblock amp as they usually have better THD and damping and I don't need a ton of power to run a single sub //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif for SPL though I would go Monoblock.

I dont see how that would add to the sq. Care to fill me in on that?

^How a Class D amp works.^

An A/B amp uses the output devices to control the wave linearly so the high frequency distortion that is introduced via the class D method is never added to the signal which results in a more pure signal.

Class A/B signal > Filtered Class D signal for SQ.

A true Class A has the best SQ but causes a relatively significant DC current to be applied to the speaker.

They make Class A/B mono amps. Given that an A/B amp is less efficient, it requires more power to operate at the same output level as a Class D.

People that can hear it will say an A/B sounds better. People that can hear it will say a Tube amp sounds even better.

I had some CD's back in the day that had different Bass tracks on left and right, That was cool to listen to.

no one can hear the difference FYI.

If you say so.
