Why not? You'd just need a 1/4" in and a speakon out.
I'm waiting to see if the bass amp makers start using these newer generation modules in their heads. They tend come out with new models (using new modules) at more or less the same time. IcePower has been the most popular since the beginning of the class-d revolution. My amp uses an older generation module that's rated at 500W into 4 ohms. It won't do 2 ohms. Newer versions are rated ~800W into either 4 or 2 ohms. I believe these all have lousy distortion specs at full power. But bass is a bit forgiving of this.
Would be cool to see little amps that could the put out 1K or more into 2 ohms, without noise or distortion problems. This would lead to lots of flexibility (ability to use 1 to 4 speaker cabinets depending on your needs. I suspect price is still a problem here. And the demand for lots of power seems to be going down as more venues get modern PA systems.
Please forgive this tangent.And now, think about the effect of output impedance of DAC or preamp to such DUT.
You are wise enough to suspect 2 Ohms is danger zone and it is danger zone for amplifiers of most designs. Stay away from it.2ohm sounds like too little of a load to push so much power, but im far from an expert
Wouldn’t the speaker cabinet be the limiting factor in transportability of guitar amplifiers?2ohm sounds like too little of a load to push so much power, but im far from an expert
In my mind, having a pedal format power amp that can output 200w@8ohm for less than a 100€ and a larger enclosure one that can output 800-1000w @ 4ohm for 500€ would be great products that the market is ready to consume.

Thank you but how is that related to a high power amplifier like this one to possibly be used for guitar amplification?They are and arent at the same time. Modeling and DSP are so good at the moment that you dont need the cabinet unless theres absolutly no other way to produce loudness. Most touring bands plug directly to PA on venues, and to a computer with studio monitors or headphones at home or rehearsing, most recording studios have gear on site that they know how it works, how to mic it and how to mix it, so the cabinet a musician would transport is redundant there too.
OK it is a reason I rarely contribute to forums these days and probably won't be again here - the abuse is too tedious. But please make sure in future you are even handed in your deletions and don't give special treatment to Grand Contributors and Forum Donors.Some more posts deleted as off topic. Some of you are flirting with disaster. Last verbal (typed) warning.
If you look up you will see everything was deleted. Sometimes the forum doesn’t update because you still have the page loaded in your computers buffer.

Hello Rod, I'm sure many members here would be interested in your experience in speaker design, so I would suggest to take the comments about your Hypex NCore DIY amp posted with a grain of salt (although she wasn't pretty) and stick around.probably won't be again here - the abuse is too tedious
Is that a highway to the?danger zone
Ah, excellent!These results show the Hypex NCx500 to be even more remarkable than my original testing showed!
OK, I investigated the cause of excess distortion at higher power. I had noticed that with buffer setting distortion had gone down which should not have been the case. I noted on the graph that my dummy load connection may need revisiting. Indeed that was the case. I use screw terminal locking banana plugs. The screws sometimes come loose. I checked and they were tight. But under instrumentation I could see that wiggling the wiring caused good few dB change at higher power. So I tightened them to death and result was much improved performance:
Due to lower distortion, we could eek out some more power at 1%THD so I updated the max and peak measurements as well:
As I expected, the impact here is lower due to much less current travelling through the wiring terminal. Still, we get closer to state of the art. As an aside, I verified that the Purifi measurements were with high gain (re-ran that measurement as part of testing the wiring).
Finally, the lowered distortion exists at all frequencies:

The buffered results would likely get a bit better as well. I will see if I can re-test those.

Awesome the fix was so easy to rectify. Some days we can’t see the Forrest through the trees. In this particular case you did actually have a Screw loose!FYI the review is updated as well.
Does this point to the need to employ a torque instrument when tightening speakers terminal? I love my Wiha! Would the same tightening improve the recently reviewed Buckeye performance?OK, I investigated the cause of excess distortion at higher power.

I get them tight but the copper fibers of the wire compress over time making them looser. I then have to take them out get the strands together and tighten once more. I am thinking about using solder with a different ones.....Does this point to the need to employ a torque instrument when tightening speakers terminal? I love my Wiha!
