What Class D amps will drive a 2 ohm load

Not at all in your wheelhouse, just an FYI option I overlooked mentioning in my earlier response.

I drive a pair of 3.6 ohm Avalon Acoustics Eidolons off the 4 ohm tap with the earlier less powerful 180s with aplomb. Compared to an MFA D75 which would run out of steam and the Hypex nCore 400s described in my previous response.
Point-to-point wiring, low heat, group biasing, switchable feedback, and untypical low maintenance. Again, just an FYI.

This statement is false. The ability to double power as load impedance is halved has nothing to do with how well the amp will play bass

Of course it does when it demands current into low impedance to do it, get over it.!

Ralph you’re so transparent.
Stick to what your good at, super efficient easy to drive horns that you heavily promote and your OTL’s, that can’t drive these kind of sub 2ohm inefficient speakers that you have no love for. But then yet in the same breath, promote the use of your OTL’s with them, with expensive Zero autoformers, saying that their great and the perfect answer for your OTL amps to use on these hard to drive speakers, just to make some more dollars from the gullible.

All your doing here, is to branch out into the Class-D gravy train $$$’s (so transparent) without any loyalty to where you came from, OTL’s and horns. But then they are both a dying breed.

@atmasphere Although we just got news this week that the USPTO is granting our class D patent with all 20 claims supported

Congrats Ralph, finally 

@georgehifi  super efficient easy to drive horns

Hi George, been following these class D threads, what's wrong with efficient easy to drive horns? I'm a neophyte in these matters and trying to learn.

Thank you
