What Class D amps will drive a 2 ohm load

My two cents:

1) George is an extremely rude individual. Would you honestly speak to people in person the way you do here? Why go out of your way to insult an engineer who designs and builds excellent products and is wiling to impart information? Are you willing to share your audio CV so we have an understanding of your expertise, as your comments do not suggest you do not have much of an understanding of even basic electrical concepts (i.e. ohm’s law)?

2) Atmasphere is extremely patient. Thank you you for continued information. Your posts are always informative for those looking for more technical information without getting deep into the math.

George, the quote above suggests that you do not understand how a voltage source works

Yes you use this old chestnut everytime as it suits you to bring it out every time your OTL’s are brought into question doing the same thing.

So it’s simple for all, instead of doing war and peace to confuse everyone as he usually does.
dsper OP here’s is the proof, Thiels CS5 that have impedances that reach down to below 2ohms will get "driven" and sound far better "up to a given level" with the 25w!!! Mark Leveinson ML2 monoblocks, but certainly not louder than 1000w, 2000w or even 3000 watt Class-D amps, because the ML2’s can do the doubling act into lower impedances right down to 1ohm

This statement is false. Our OTLs don't double power and in fact are not intended to act as a voltage source. They are intended to act as a Power Source.

So it’s simple for all, instead of doing war and peace to confuse everyone as he usually does.

While this comment is a bit of a word salad, if I make it out right its mostly correct and doesn't repudiate anything I've said. Just about any class D amp that can make 1000 watts won't have any troubles making as much power as the ML2 will do into 2 ohms (100 watts) so what this comes down to isn't whether the amp can do 2 ohms better, its simply if it sounds better at all.

Put the shields up Scotty, we’re being attacked save the Enterprise at all costs.
On these OP’s speakers with the minuscule 25w ML2 monoblocks will do bass and everything better to a given level, than any Class-D can, and that’s because of the current it can keep supplying down to 1ohm

George,

You seem to misunderstand how amplifiers work. Take your ML2 monoblocks. They put out 14.14 volts max to make their 25 watts at 8 ohms before clipping. At 8 ohms, they are flowing 1.76 amps of current. At 4 ohms, they are still at 14.14 volts, but 3.53 amps of current. 2 ohms, now up to 7.07 amps and 100 watts of output. We will ignore anything below that, as the CS5s don’t dip below 2 ohms until the subsonic range (and even trying to put 100 watts through the 8" woofers below 20hz will cause them to exceed their excursion limits).

Now lets take a Class D amp, say the Ncore NC400 for DIY. It is rated at 200 watts at 8 ohms, 400 at 4 ohms, and 580 at 2 ohms. It has a maximum current capability of 22 amps per the manufacture. Lets only run it at 100 watts into 8 ohms, where it will be 28.28 volts and 3.53 amps. 4 ohms, still 28.28 volts nets us 200 watts, and 7.07 amps. 2 ohms, still 28.28 volts, 400 watts output, now we are at 14.14 amps, or twice the current of the Levinson and still well under the manufacture's limit of 22 amps.

An amplifier doesn’t put out more current than a speaker needs to reach a set voltage. The Ncore will maintain twice the power output as the Levinson down to 2 ohms (and below even). These are the laws of physics and why amplifier designers speak in terms of voltage, not current capability, except to establish the minimum impedance a given amplifier maintain its voltage. Put another way, even a cheap receiver can drive 2 ohm speakers, but will do so at a far lower output than at 8 ohms.
