What Class D amps will drive a 2 ohm load

That’s just adding series resistance to the perceived load to make it look higher to the amps output stage so it doesn’t complain, and what that does is lower the damping factor and raise the output impedance as seen by the amp

@georgehifi - You literally have no idea what I was talking about, so your reply is wrong in the specific and wrong in the general.

 
Best,

^^ +1 @erik_squires yes, that response on George's part surprised me as well.

last thing Colin will want to do is sell an amp that turns out to be useless!

I never insinuated Class-d's would be "useless", I said Class-D's into these types of speaker loads won't get the very best out of them, end of story. 

Hello georgehifi,

FYI, You’ve been using the abbreviation "ect" rather than the proper "etc.’ to refer to the words of Latin origin "et cetera". Translated literally from Latin, et means ’and’, while cetera means ’the rest’.
An easy method to remember the distinction is that etc. means et cetera, while ect is the typical involuntarily sound people make after reading one of your posts.

You’re welcome,
Tim

My guess is that amps with low impedance around 100-150 Hz sound more discerning

Sorry if it wasn't clear, but I meant:

"My guess is that _SPEAKERS_ with low impedance around 100-150 Hz.... "

Apologies for any confusion, I hope that to most it would have been clear I made that mistake.
