Also, you should use this format to link to posts, without the spaces. This way it works for people with different numbers of posts per page set.

Has the CV-5000 ever been tested?

I am building separate subs and need 2000 watts for 4 ohms. I am not wiring the subs together or combining them. Just trying out different things. The clone is always an option, the 4 channel one as that is 2000 x4. The bridged nu3000 comes close and could be a cheap option.

I offered to test one of them previously, but nobody wanted to send.

It would be nice to test a 5000 watt rated old school amp and see how it really does compared to the newer class d stuff. The PLX 3402 did 2800+ watts but blew fuses at the 20hz test, not sure what to think. The Inuke3000 did 1600-1700 watts and that is dirt cheap. If one needs 4 channels the XBS 20k seems to be the amp to get.

The clones are basically Class-H on roids.

As I understand it, it uses switching elements to provide only the necessary amount of power to keep the DC capacitors charged at the necessary voltage to operate the output transistors for the amount of amplification required.

Instead of having a big blob of copper and a rectifier bridge and large stepped-voltages that are either too-much or not-enough...
That's why it's ~90's efficient vs ~40's efficient

The output transistors on the clone operate in Class-B or something like that...
The clones are not Class-D.

Class-D takes the wall-AC and switches it directly into unfiltered signal-AC, and then pushes that into the (~30khz) filter banks.
This is why it is so lightweight and efficient. The hard part is finding transistors that can switch at the voltage/current/power levels required at hundreds of kHz.

You may see some better technology leaked to the public soon-ish, the DOD just got their patents approved for room-temperature superconductors and anti-gravity amplification just a few days ago...

About flipping time!!! They've only been hording this tech for ~70 years!
This is world-changing (and hopefully not world-ending) tech. One cannot stress enough how IMPORTANT this news is.

So I am looking for an amp to power my subs and I forgot I had a broken IPR2-7500. I am going to get it fixed and use it. It should be as good as my SP1-4000 above 10hz.
