Thanks man I'm going to pick up everything Today and run it tonight. Grabbed 250ft of 10/2 yesterday. Needed 125ft but from 100ft to 250ft roll it was only a 30 dollar difference

Jeremy I can’t wait to see if you have the same issues with amp hiss and hum I’m having. It’s a royal pita dealing with. Only one amp hooked up and it’s all good. Hook up both and it’s a mess.

So now that I’m getting the whole ground lift thing done(it completely silences the amps)
I’m wondering, are there red clip lights on these amps? If so, I’ve pushed them and not seen a red light yet. Just wondering when clipping actually starts. Seems the front panel is marked -4 then clip.

Mine does. Now that my gain structure is properly set, I don't often get to -4. The only time I've ever notice clipping is when I left the added low-shelf filters applied in the mini. The extra low-shelf are for the movies that have neutered bass.

Cool. I guess I’ll push these harder 🧐 I just gotta see the red. I’m feeling bad for my house with all this bass. And I know the amps can do more.

No humming or hiss here with my 9 amplifiers.
I use real XLR, not fake XLR, and all of my stuff is well grounded to one spot, and my house is optical, not coax; all of which helps a lot...
You must have a grounding issue somewhere, could be in the house wiring or one or more bad amps, or some other source entirely (cable box connected to tv/projector/avr etc...)

The clones turn their red clip lights on during boot.
If you don't see them, then there is something massively wrong (i.e. you might be clipping it and don't know it.)

I've only clipped 1 of the 24 xbs channels, the one powering my SAB-24 @ 2-ohm, and that was only by sending it a continuous sinewave at almost full excursion. It did light up as expected.

Keep in mind that -infinity to -4db is the first 40% of the power from these amplifiers, the remaining 60% occurs between the -4db and VPL/CPL LED (which ever comes first..)

5th gear is brutal isn't it?
The first 1600watts happens up-to the -4db LED, and the remaining 2400watts happens on the -4db LED

or double that, for 2-ohm or bridge-mode
It has a BIG 5th gear...

Congratulations: you've sent the first 1600watts to it... now send another 2400watts to it!!! Why does it smell like burnt-coil in here?

The clone amps are sort of deceiving that way, you think you might be nearly clipping it, but you might not be...
That said: most pro amps only have a -6db and clip or -3db and clip, so that is pretty common actually...

The CPL and VPL are both clip LED's. the CPL is yellow/orange if I recall. Current vs Voltage.

My hum/noise is completely solved.
All I did was snip the #1 pin xlr wire and isolated the second amp. The 1st amp is still hooked up as it was. But now they are both dead silent. No noise, hiss, hum at all. I’ll have to actually look at the amp when they startup. I just don’t remember seeing a red led. I’m sure it’s there. Yeah these are very powerful amps. My screen and screen wall panels barely stay in place now during big bass. The screen gets super wavy. Lol. Still trying to find the systems limits and where I like it all tuned. I love the amps though.

:-) my screen does this twisty thing at full power like it's bunching up with just the two 21DS. Its most prevalent during the John wick 2 cave shootout scene. When he moves to the shotgun the real fun begins! It's pretty fun.

If you ever need even more power... there is always a bridged 14k per cone!!! 4kW vs 14kW

That depends.

But in any case, in that configuration it STILL HAS more-than double the continuous power of a single channel of a 10k or 14k or 20k.
(and a single channel of a 14k is no slouch to start with, so there you have it...)

Yeah, I am not technical with this stuff, I leave that for the guys like Notnyt. I just try many things for myself based on their work. That said I am pretty sure the bridged Sanway 14k and Smith 14k will do 4800 watts for 2 seconds and then 3800 watts, something like that. That is good stuff but 14k burst will not be useful in real life except for not clipping with a quick transient. At this stage of the game we should be building systems that won’t need a 14k millisecond burst. I would concentrate on the continuous power. The clones have great power, but with great power comes with great responsibility.

That is good stuff but 14k burst will not be useful in real life except for not clipping with a quick transient. At this stage of the game we should be building systems that won’t need a 14k millisecond burst. I would concentrate on the continuous power. The clones have great power, but with great power comes with great responsibility.
The 14k has 3-4db burst potential even at 20hz. That's still pretty nice.

I agree, but calling it a 14k watt amp is misleading as it lasts very, very short, still very good protection as the other amps don’t burst like that. BUT, the other amps(speakerpower) have built in protection to begin with. I loved my clones and still might buy the 20k when I add two more XXX-18s. 2kx4 is pretty awesome in one package for the price. The price difference is pretty large, two of my sp1-4000 for $2000, triggers, warranty, protection, etc or one clone for $750 and without features. Hmmm.

Doing math is useless. But I can "try" to take the numbers right off your own measurement thread,
although you never tested the sustained figures for stereo 4-ohm vs bridge 4-ohm on the same model of fp14k (or if you did, you never posted it. i.e. for the 2-ohm stable one obviously.)

You only posted the burst figures, from the older model vs the newer model.
So that's all we have to go off of I guess...

(4.4) ohms at 40hz

With two channels running 116vrms/6kw
Your posts aren't clear if that's 6kW or 3kW per channel. So again we have to make additional assumptions.

If it's 2x 3kW burst, then 13.1kW burst is more than double per cone.
If it's 2x 6kW burst, then 13.1kW burst is more than double per cone, still...
I'd imagine sustained won't be too much different, as far as making double power at least.

You never mentioned what the sustained power of the 2-ohm stable version was/is.
But based off the old one we could assume it's likely to be 2x [email protected] and 1x [email protected] based on your comments about sustained power of the old version in stereo mode.

You'd probably know more about the precise-figures, after all, you're the one who tested like 4 different variants of the fp14k.

Had you posted the burst and sustained powers for all variants, we wouldn't have to speculate or guess what the sustained power of the 2-ohm stable version is in stereo 4ohm vs 4ohm bridged. So: do tell...

Until then, I will continue to assume bridge-mode is "nearly double (or better...)" than stereo mode.
and additionally that: the bridge-mode of a 14k will "easily out-do" a single mono channel of a 10k, 20k or 14k LOL

I can't see how double the transistors into half the ohms won't produce WAY more power (for the models rated for running in that mode, I might add...)
