Subwoofer Class A/B vs D Power Amplifier

Not that there aren't differences, but whatever difference there is pales in comparison with the difference between using just one and using three or four. Whatever the budget, you'll get better results using it to buy four than putting it all into one. Search Swarm, distributed bass array, read and learn what I'm talking about.

I don’t think it’s any big deal using a class D amp with a subwoofer. I use the JL Audio D110 and I think it is outstanding. I have never owned a REL so I can’t give you an opinion on it. But I can say that the JL is better than other subs that I have owned!

I concur with Millercarbon.
Using at least a pair of subs is the way to go.
I know Audiokinesis has a Swarm system that is supposed to be a killer.
For me, I use a pair of Vandersteen subs, which use a high pass filter to help seamlessly integrate them with the speakers.
Class D amps are relatively inexpensive to build compared to Class A or AB. Considering they will be only powering lower frequencies, I would say it shouldn't make much difference sound-wise, but, I may be mistaken.
Perhaps Ralph of Atma-Sphere could chime in....

I don't think a dual sub is needed, and not what the OP is asking about.


OP: I wouldn't worry about the class of amp. I'd worry a lot more about room correction. JL has one of the best.
