maybe I am an old fart. but I like class A/B or class A

in a car it might not make as much difference because of engine and road noise. but I havent heard a class D, even high end ones, that sound as good as A/B

one big consideration for class A/B is the zero crossing distortion though. if you go with a high efficiency setup (or HLCDs) then a system where you are using 1-2 watts of power can suffer from that. the sound difference from an 8ohm driver vs 32 ohm was drastic! the 32 ohm required about 100 watts of power to get 12 watts out of it, but it sounded so much better.

for subs, I owuld say that class D is fine. when you are talking about 1000+ watts for a sub, then class A/B 50% effciency starts to be a practical issue from a current standpoint.

 

TY Minbari. I almost forgot I posted this. Okay, but then the issue with finding good strong, efficient mid bass drivers which are 2 ohms. In my search, I found 12" pro series mid bass drivers which could take 1000 wts RMS. Good luck making 1000 wts RMS with a class A/B amp 😕 ....even if your drivers are only 2 ohm.

 

...
... I guess the trend nowadays seems to be, in using a 4 ch amp (usually a Class A/B) and bridging it to make two channels which are decently strong enough to power the mid bass drivers. But why can't one find a really nice, strong 2 ch Class A/B ? Say 500 or 600 2 ch ?
...

I really think the trend nowadays is to use a class-D.

...
And what kind of difference would one find using a decently strong 2 ch Class D amp, vs a Class A/B that had to be bridged ?
...

I sort of doubt you would honestly be able to hear a difference.

If someone wanted big power, they probably would want to reserve class-AB or class-A for tweeters and/or MR.

Your probably right. I was just kind of looking for a general consensus.

 

I think you can find ballsy sounding amps on both sides. It's been a while since I've ran A/B and don't feel like I've lost anything. There's differences between amps regardless how they're compared whether it's amp class vs another or amps within the same class. You just have to find the right combo regardless of class.

Man & Machine... Power Extreme!

Okay, could be. BTW, your not using class A/B on your mids/ highs anymore ?

 

I think if you can try it yourself. I tried and i didn't liked it. I was running Audison Lrx 4.1k and Audison Lrx 2.150 which i replaced with Helix M six and Helix M one. I didn't liked the mids and highs with m six. I switched back to Lrx 4.1k for highs and mids and Helix M one for sub. I couldn't make it work with the m six. The sound with audison is more open with better stage. I don't know maybe I'm missing something...
