Oh well.
I've watched "Williston Audio Labs" YT channel and it reached the spec. If we open the PDF of the inuke 6000 and scroll to page 13, we can see
1100w at 8 ohms stereo and 2200w at 8 ohms stereo. Which is really close to that "Williston Audio Labs" measured with the amp dyno.
He measured 2x ~1250w stereo at 8 ohms and this is under 1% THD.
and 2x ~2000w stereo at 4 ohms. That's pretty close to the papers.

I don't have any other choice than the behringer 6000 series amp because of my home location =/. Oh well. At least it's cheap even if we does half of what's written. I can always get another 1 i guess.

Those tests are inaccurate. It won't put out anywhere near 4kw.

At least not for subs. Maybe near 1,000Hz?

Don’t think a speaker exists that will take 4K at 1000hz.

Plus the poster above wants to use it for the UM18, it’s a good combo.

No, it's a power supply limitation. That's all the amp is good for. I've published the numbers by frequency even

This is the problem on so many audio sites, taking published docs, or YT tube videos as Gospel.

As opposed to asking owners of the amps, who use them with PA rigs, how do they perform.


The most accurate tests I've seen, were published on Speakerplans.


I can say that, because my mate had a pair of lovely Void Infinite 8MK2s, and because someone offered ludicrous amounts for them, he not only sold them, he unforgivably, bought 2x Behringer Ipuke 6000s to replace them.


The Behringers clipped like Christmas trees, when he tried to play them, 2x PD1850 18" drivers per side, full tilt.


I convinced him to sell the 6000s, and get Berry "12ks" () instead.
Slightly better, but still could not compete with 4x drivers on the Void 8MK2.


After he finally accepted the Behminger Ipukes, are just cheap tosh, with lies as specs, he got rid of all his Behmingers on Sub, and now has Powersoft K20.

Lesson learned: Don't buy cheap sh*t, and expect Top brand performance.

To my knowledge the iNuke 12k is almost the same power at 8 and 4 Ohm and just adds 2 Ohm stability. Could've been rumours thou which turned out to untrue.
And going from an iNuke to a K20 is a pretty ridiculous change. About the same as my swap from a Behringer PA to l.acoustics.
But the K20 has 3x the power of an iNuke 6k on paper, so that's quite a difference already.

I've read the posts about it.

What if i change the power supply with a beefier one ? Is it possible or just a waste of money ? Because even a modified inuke 6000 will probably be way way less than the alternatives.
I don't plan on running the subs more than 600w and i want to have at least 3db of headroom, they will be ported at first but i might switch to closed boxes if i get a total of 4. Then i will need more power. But this is way way in the future so i could probably get another amp too.

Any recommendations i can check if they exists in Europe ?
Thanks!

changing power supplies is not trivial, you might as well just make an entire amp at that point. Or you know, just buy a better amp... fp clone, prolite 7.5, etc.

I am trying to work out which pro amps to consider to run my modular towers, which are obviously full range. Will be potentially retiring my Emotiva AB amps for the task, so, hopefully dont go backwards in audio quality in any way.

Any recommendation on which pro amps to consider, also, importantly, which ones are reliable and not insanely expensive. I would need 3 channels per speaker, so either will need to b buy 5x 2 channel or 3x 4 channel amps...

Curious as to why? To keep the power all located in one place?

Yes exactly. And the speakers already exist (along with the cable runs), plate amps require cutting into boxes or making other boxes to house them which I am not interested in.

I've never liked the idea of plate amps. I would like my amps all as close as possible to the processors.

Also, eventually these will be behind a screen wall, another reason, dont want to shut in electronic devices like that.

I dont really want to clog this thread, I just thought there would be some summary I guess on what the overall consensus was on pro amps and which one the majority are using for full range. I'm actually considering just buying 5x NX3000DSP's at this point.

Inukes are pretty bad at high frequencies and would be a shame to put a lousy amp on a great speaker imo.

These are highly rated, perhaps one of the best measuring amps:
https://www.diyclassd.com/product/nc...omplete-kit/24. You might want to ask around, I think the power supply for the Hypex amps can drive two channels, which would keep overall cost down quite a bit if so.

Another option? https://www.d-sonic.com/amplifiers/m...three-channel/

Hmm I guess at this point I will probably just buy 3x XPA-3 Amps, and go hard on Emotiva. Already have an XPA-7 and A-5175 and both excellent... so I guess I will use one XPA-3 for each speaker. then free up the channels on the other amps for my other 12 channels I will need.

They are active. I will need 9 channels to run my LCR. So I'm not looking to buy 9 monoblocks really. Three xpa-3 would be the upper limit of spending for sure. I run the L/R on six channels of my xpa-7 right now and I'm not missing out on anything for sure, but adding a third active speaker is going to require a bit of a shake up and afford the opportunity to make a little bit of a change.

They would be about 100db/w easily.

I found lab gruppen's C series to be excellent cost per channel for the performance. You can pick up a used C20:8X for one grand if you're lucky. That's 8x 250W into basically any load, all channels driven. Comes with PFC and controlled fans. You could bridge four channels into two to get a 6 channel amp with 2 more powerful channels for the bass bins. C20:8X for LR and C10:4X for the center. That makes a total of 9 channels with the bass channels being twice as powerful as the others. Sounds perfect to me
Ok now, to connect this to the actual thread.. I am planning on getting at least one C20:8X for my HT once I get a dedicated space and I will bench it then.

Have you used one of these amps? How bad is the fan noise?

I have not used one yet, sadly, but as far as I know the fans turn off when there is no output signal.

Dang it, can't find any of the good amps tested in this thread in Europe. =/
The only thing i can buy (expect the behringers) are the fp10000/14000.... clones from aliexpress or from china.

The nx6000 and the nx4-6000 are dirt cheap here. If i convert the currency, the nx6000D is 464$, without the DSP is 407$ and the nx4-6000 is even cheaper at 362$. This is after tax. Shipping won't be more than 5$, i might even be able to get them locally.

There aren't make people in my country into serious sound. We don't even have good subwoofers. The only option is the ultimax 18 from the Netherlands, and because they are imported from the USA, the prices are 2x. 468$ a piece right now.


The fp14000 clones don't even have a brand, i don't see Sanway or anything. It just says "SMPS Power Amplifier". At least they are quite cheap. Between 585$ and 720$ + 110$ shipping.

Oh well.

The only thing i can buy (expect the behringers) are the fp10000/14000.... clones from aliexpress or from china.

The nx6000 and the nx4-6000 are dirt cheap here. If i convert the currency, the nx6000D is 464$, without the DSP is 407$ and the nx4-6000 is even cheaper at 362$. This is after tax. Shipping won't be more than 5$, i might even be able to get them locally.

There aren't make people in my country into serious sound. We don't even have good subwoofers. The only option is the ultimax 18 from the Netherlands, and because they are imported from the USA, the prices are 2x. 468$ a piece right now.


The fp14000 clones don't even have a brand, i don't see Sanway or anything. It just says "SMPS Power Amplifier". At least they are quite cheap. Between 585$ and 720$ + 110$ shipping.

Oh well.
Search for SINBOSEN or SANWAY...

@notnyt , any idea how feasible and how beneficial it would be to substantially upgrade capacitors in an NX6000 to improve burst a bit?

@notnyt you interested in testing a plate amp from Ram audio. Specs say 3000 watts RMS per channel @4ohm . For $1100 I going to grab one.

I assume you mean the SB6K-Bi

Drop me a PM and I'll give you shipping info whenever you're ready

These also look interesting...
