I was just wondering out of the blue if there were any tube subwoofers, if not why not. Also are there any class A/B or other types beside the ubiquitous Class D? Just trying to learn more. Thanks
The NOLA Thunderbolt sub uses an A/B amplifier. I haven't heard it, but it's received excellent reviews from both reviewers and users. It's not tubed, but is considered more of an audiophile subwoofer than most.
You don't see any tube subs because it is such a bad idea. Tubes can't control bass very well, tubes can't drive low impedences well and there is a loss of bass when you go through a mile of output transformer wire. And there would be lots of microphonics from the tubes shaking.
