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,

Why do loudspeaker manufacturer's make ultra low impedance loudspeakers in the first place. lots of great speakers out there with easier loads to drive, many as good as, or better than Thiel. IMO.

IcePower is rating their module in a conservative way.  2.7 ohms is three 8 ohm drivers in parallel.  They are selling this amp for concert use and sub woofer use as well.  You don't want your loud concert shutting off because the amp is going into protection.  As I stated above, the IceEdge module measured 1000 watts into 2 ohms (1400 at 2.7 ohms) on the bench here yesterday.  It drives his Thiel 3.7 better than his previous Bryston and Modwright amps.  It is perfectly compatible. If you need more power than 1000 watts into 2 ohms then your speaker is really HARD to drive.  Certainly the JC1s will give you 2200 watts into 2 ohms.  But they do not sound that good by todays standard. 

There are many speakers around $2700 that would sound better and be easier to drive than an old CS5.  But, selling those speakers would be hard.

I could care less what class of amp will drive whatever speaker.  I have been using a 92 db speaker for years with a 25 watt class A amp.  Now I use my 600 watt a channel class D and get better sound.  I don't need 600 watts....25 was perfectly fine.  I just want the best sound possible.  As I said, I don't think low sensitivity, low impedance speakers make any sense.....not in todays world.  The times, they are a changing.

George, no negative comments here, please, but my point I am about to make is very relevant to the discussion, and just another person’s perspective. As most here who know me, I go wayyyyyy back with PWK and his Klipsch Heritage products. I have owned, borrowed, installed for others, and listened to, so many other speakers, and the same goes for power amplification. As much as I enjoy, and own, Heritage, I am certain, part of my enjoyment, comes from the driving amplifiers, simply " coasting along ". You do not hear a speaker, without a driving amp, nor, do you hear an amp, without a driven speaker. It is always, imo, and ime, the combination. Some of us hear an immediate " compression "; some of us hear certain " distortions "; some of us hear a lack of " damping " ( woofer control ), etc. If there are any questions, that reliable measurements cannot tell you, you simply need to try it....On another thread, I recommended to the readers, to read a review of the Peak Consult Dragon Legends, from Mono Stereo, last year, by the same reviewer who just reviewed the Merrill 118s, from Part Time Audiophile. After reading the Merrill review, and realizing I had read the speaker review a year and 1/2 earlier, I needed to read the speaker review, again. Richard Mak, the reviewer, does an excellent job, in both reviews, but, really highlights, greatly, the importance of the speaker / amplifier interaction, and most important, the expectations of the listener. Please read them both. Enjoy ! MrD.
For about $3k you can get an nCore NC1200 based stereo amplifier from Nord/Apollon that drives 2 ohm speakers with 1200W. Plus your choice of Sparkos or Sonic Imagery discrete opamps to flavor to taste.

IMO this is a huge value.

I don't need that much power and settled on "only" 550W in 2 ohms of the NC500 for my Thiels. That is plenty of power, lowest distortion and non existing hiss and noise.
