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,

My guess is that amps with low impedance around 100-150 Hz sound more discerning

Sorry if it wasn't clear, but I meant:

"My guess is that _SPEAKERS_ with low impedance around 100-150 Hz.... "

Apologies for any confusion, I hope that to most it would have been clear I made that mistake.

OKAY......

This is the OP again...it sounds like I am hearing Class D might not be the best for tough, low impedance load speakers.

If that is indeed the case, why is this and what has to change in Class D design to achieve it?

Please respond realizing I know that doubling down from 4 ohms to 2 ohms by an amp is a good thing; but I probably cannot explain why this is so.

Trying to learn. Seriously.

Thanks for listening,

Hi DSPer,
There are a lot of linear amps which are also not great for low impedance loads. Like those, many Class D modules are designed for more normal loads.

Some however, like Hypex, have been rated down to 2 and will do a very good job.

Just kind of depends. Where Class D tends to have more of a problem with speaker loads is at the top end. Think ESL's with dropping impedances, but again, a lot of linear amps have the same issues.

Above all, assuming they are rated for the speaker, you should listen. You never know what serendipity will bring you.

Best,

We have sold many of our amps for the very reason they can drive very difficult loads with loads of current. They will drive 2 ohm speakers with ease and aplomb all with a very satisfying sound quality.
You would have to spend considerably more £5-10K and choose a direct seller boutique manufacture to better.
