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,

Holy crap - 49 amps. Didn't know this one existed

https://www.hypex.nl/product/nc2k-oem/79

Here's Apollon's version:  https://www.apollonaudio.com/hypex-nc2k-monoblock-amplifier-apollon-audio-nc2kslm/

Yes, 2,000W in 2 ohms. Tell that to some who believe that say a 100W/200W/400W in 8/4/2 ohms amplifier would be more suited to drive 2 ohms speakers just because they double power as impedance halves...

Sorry but what you get is a good PA amp.
Hypex suck in, they purposely put things backwards to confuse at glance. Look again, and that’s peak watts and amps, also the wattage go backwards as the impedance goes down, it gets severly current starved.

Nowhere in this universe can this thing come close to doubling into 2ohms The NC400 of theirs is a far better module as far as current delivery into low impedances it actually goes up in watts instead of down. Data sheet download here

This just gets more interesting.

I emailed, to both Nord and Appollon, the Stereophile measurements for the Thiel CS5's and both suppliers said that their amps would drive them.

For example, Appollon replied that their NC1200SL HYPEX NC1200 BASED AMPLIFIER "...is a perfect choice for your speakers and probably the only class d amplifier that will drive your speakers with ease at 2 ohm loads. The NC1200 module is specially designed for such low impedance loads. Any other class d amplifier will fall apart sound wise with your speakers but the NC1200 shines @ 2 ohms."

So what am I not being told?

:)  Apparently you're *not* being told that the amp won't work...
And FWIW, if the amplifier has a low enough output impedance, it will act as a voltage source even with a 2 ohm load. It **does not** have to double power to do that.

(Without seeing any independent tests)
Of course they did, they want a sale.
No one disputes that they can’t drive the Thiel CS5’s to a point, just if they don’t try to double from 8 to 4 to 2ohm, you won’t get the very best out of them, they will be compromised in the bass, if you don’t mind that that go ahead.

But not if you drove them with amps like the ones I have described, that can come close to doubling wattage all the way, from 8, 4, and 2ohms, I believe the Thiel’s are worth the right amp to make them sing top to bottom, don’t you?? it’s up to you.
