class d and class a/b sub comparison

[squeak9798 5,000+ posts]

In an SPL yes but in an SQ environment I'd use A/B for low distortion, better damping, decent efficiency, and dynamics control.

Helotaxi nailed it on the head.

Nearly all quality class D amps have inaudible distortion.

Nearly any non-tube amplifier will have more than adequate damping (DF isn't a "higher is better" spec)

Efficiency is only "decent" for class A/B at or near full power...which you will hardly ever be operating at with music.

Dynamic control is the company that owns Dynamat, and that's about it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

let me clear things up a bit

im not sayin class d amps are better than a/b amps, they both have their place, im simply saying class a/b amps sound amazing on sub duty IMO. Now i expected the rubi to sound better than his MA since that rubi sounds better than most of the amps i've heard to date, but, what i don't understand is why more people don't run a/b amps on bass... seems like around here the general census is to ban class a/b amps on sub duty... matter of fact i don't even know what the fuk im talkin about, im drunk and tired, i haven't had pus*y in 4 days and im fiending, this one broad i mess with been with her b/f now for almost 4 years. Me with my dum *** has no problem with beatin it up with out him knowing, just to make things worse im friends with him sorta. I know him from other people and i've skipped school to hit up the french quarter with him back in the day... shiit is crazy im going to take a ride.. bye all

Nothing wrong with running A/B to the subs but if you have the choice and plan on running any amount of serious power, D is the only way to fly. This is coming from a guy who has only ever run Class A/B amps for subs. Watching my lights look like a disco despite a 195A alt and dual batteries was a sight to behold. That was with an 800W A/B amp. I can almost promise you that the difference you heard was one of more power. Unless you went to the trouble of power matching, which I know you didn't, being able to hear the difference between those amps means nothing.

I roll my eyes at all of the things said in this thread //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

That's cool we usually do the same thing to your posts...
