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. |

Looks like there’s still no takers willing to put it on the line, and post up the 8ohm, 4ohm, 2ohm wattage measurements just before clipping, to see if they are "almost" doubling the wattage for each halving of load, so to prove if their amp/s are going to drive these types of speakers close to their best, not just "satisfactorily"!

I just read this article about Purifi Audio, and their class D amp that is said to be "completely indifferent to frequency, level and impedance variations, with measured intermodulation distortion way below any other technology." There's no mention of power doubling down all the way down to 2 ohms but an amp that is completely indifferent to actual speaker impedance variations seems promising, right? Here's a direct quote from the article: "The first product to be unveiled by Purifi is the 1ET400A, a 400W Class D single-channel, analog-input, amplifier module. Effectively, this is the module used in the prototype Lyngdorf 8 x 400 Watt Class-D amplifier shown at the ISE 2019 show. The technology is said to be completely indifferent to frequency, level and impedance variations, with measured intermodulation distortion way below any other technology."

There's no mention of power doubling down all the way down to 2 ohms but an amp that is completely indifferent to actual speaker impedance variations seems promising, right? That's because it can't, here is the a snippet from the manufacturer's data sheet, which you can take with a grain of salt normally, independant would be even more revealing usually. As you can see at 1% distortion!! the 2ohm watts didn't double at all from 4ohm, the 8ohm to 4ohm came close to doubling though. And that little 1 next to 450w said went into current limiting on 2ohm. https://ibb.co/YcQ8xV7 Cheers George |
