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,

Dsper

One of the suggested amps (1200AS1/2) is rated at 2.7ohms. This module also has a clipping indicator built into the controller. It would make sense to me that the clipping indicator was active to see how well the amp is doing. I doubt B&O had something like the CS3.7's in mind when developing this module. Based on OP's last post, it seem the question is if there's a Class D amp that drops down to 2ohms without any issues, while maximizing the speaker to it's full potential. Not a Class D amp that only allows a speaker system 40-50% of it potential. Is there a Class D amp that will do this, if so which ones. According to OP, the 2 that were mentioned failed.

The "rated" lowest manufacturer suggested impedance for the IceEdge is 2.7 ohms. But in "real life" it puts out 1000 watts at 2 ohms. What a manufacturer recommends and what is real are sometimes far off. Again, the person with the 3.7s can blast as loud as he wants and it sounds incredible. What more do you want? A spec that makes you happy? Reality makes the owner happy. You don’t need an amp to double its power as it halves its impedance at 2 ohm. You just need enough power at 2 ohm (or whatever ohm) to control the speaker (assuming you have a speaker that needs that) at the volume you listen...again, I feel such low impedance speakers are outdated and don’t make "sense". Almost all amps (no matter what class) make more distortion (measurable) and have less damping factor the lower the impedance. Hardly any amp measures good at 2 ohms. Again, why have such a speaker? No way an old Levinson sounds as good as this mono tweaked IceEdge. But George will just keep repeating the same old lines (he hates class d...unless it has GaNs and has 1.5 meg switching). 100 watts into 2 ohms is not 1000 watts at 2 ohm. And my IceEdge modules beat my super simple super tweaked custom mono class A amps (also 25 watts a channel and will double/double all the way down to 100 watts into 2 ohms). The IceEdge module is current limited at 38 amps.....it is not unlimited. No one ever said it was. It will drive 95% of all speakers to whatever levels someone needs and sounds very, very good. Not state of the art...but very good. Again, here is what it actually does: (600 watts into 8 ohm, 1200 watts into 4 ohms, 1400 watts into 2.7 ohm and 1000 watts into 2 ohm). If you need more power than that then you must look elsewhere.
