Do class A/B amps "hit harder" than class D?

Gunz4me you are right. I guess I openned up a can of worms. I will admit though that class D amps not run @ 1 ohm especially with today's technology have caught up in sound with the class AB amps.

I guess you have been around, like myself. Do you remember in the late 80s and early 90s when everyone was running the Orion HCCA 225 @ 1/2 to 1/4 ohm? They were loud, but in my opinion those setups sounded like garbage, especially on rock/metal.

I am sure I will start something here myself, but in my opinion, 1 ohm class D setups are more for SPL than SQ. Granted, damping factor isn't as important as it used to be because the highly inefficient subwoofer drivers out there on the market today have a suspension that can make up for the lack of damping. You can blame my old school roots, but 1 ohm and sound quality just do not go hand in hand!

IMHO some of the best sounding amps are class AB and of the high voltage/high impedance variety. If you want to go LOUD and give up a little SQ, then you go high current/low impedance class D.

With regards to SPL, I will still stick to my guns and say that a class AB amplifier and a class D amplifier with the same RMS power should make no difference. In theory, a class D amplifier should draw less amps from the charging system than a comparable class AB amplifier if they put out the same RMS power.

class z are much better

I remember those day in the late 80's. Bridging the Orion, the Punch 45 amps down to 1/4 of an ohm load was more about playing around and seeing who can be the loudest than being who can be the clearest. I am all about sq at this point in my life but like a little extra thump on my back every now and then. Hopefully class D technology will catch up to a point where it won't make a difference anymore.

Good thing I don't need no stinking Class D for subs:

After a trip to TIPS for high voltage modifications the amp on the left should give me 1,100 RMS @ 8 ohms and the amp on the right should give me 850 RMS @ 8 ohms. Dynamic power will be 1,700 to 2,100 depending on the amp in question.

how about class DD?

I threw a class A/B amp at my boy once, he got a bruise and started bitching

....then I threw a class D amp and it knocked him out

I guess Ds hit harder

corny joke I know

If you drop them from higher above the ground, yea they hit harder.

It's been there, for over a decade.......
