What Class D amps will drive a 2 ohm load


Just asking.

I see specs into 4 ohms but nothing into difficult speaker loads (like Thiel CS5's).

Thanks for listening,

Wow!
The Wilson Alexia’s get into areas of the Kappa 9’s for difficult to drive?
Did not know that, thought all Wilson’s were very efficient speakers.
Yes efficient 90db like many Wilson’s, but a right b***h of a load like most them also, EPDR (impedance + phase angle) down to 0.9ohm!!! in the bass.
OTL’s will drive them, and pigs might fly!! What was that Supertramp track? oh yes "Dreamer"

Having read this very interesting discussion in its entirety several times I have to ask the commentators a question since neither the pros or cons truly answered the original Inquiry. 
Let's say I want to take a plunge into class D but do not want to revamp my entire system  and  the speakers in user are rated at 90db efficiency with nominal impedance of 8 ohms 3ohms minimum.  Can a class D amplifier (let's use 300w per channel)do justice and get the best or close to the best from the speakers? 
Let's hear your opinions.

I've already noted how easily the AS1200 can drive my Thiel 3.7s.  These -  https://www.muraudio.com/sp1  (and it indicates 2 ohm minimum and they are not super efficient) were used by Merrill Audio at the 2019 Florida Audio Expo and sounded great.  I've seen a bunch of other examples at shows in big rooms (e.g. 2017 RMAF with a Wyred4Sound Class D driving Acoustic Zen Maestro speakers (87 db and rated 6 ohms nominal).  I think will any product, it is too general to just say Class D as if they are all identical (same is true of any other type of amp).

You ask to get close to or the best from these speakers

Show a impedance graph with -phase angle overlay, as what you asked for can’t be answered properly, even using the 3000w!!! Behringer Class-D.

You say that speaker has a minimum load of 3ohms, if that’s in the bass and you have it in conjunction with a -phase angle of 50 degrees the amp could be seeing even 1ohm as a load, and I know of no class-D that can take that.

That’s why you never see Stereophile tests on Class-D’s that go down into the 2ohm testing, because they mostly **** themselves when it’s done.

Yes they can drive them, but I’m 100% sure your not hearing the very best from them.
As your the one who asked " Can a class D amplifier do justice and get the best or close to the best from the speakers?"
