Ipr2 -7500

3850W RMS x 1 at 2 ohms
2400W RMS x 1 at 4 ohms
1330W RMS x 1 at 8 ohms
3750W RMS x 2 at 2 ohms
2022W RMS x 2 at 4 ohms
1250W RMS x 2 at 8 ohms

Looks to me like half that of the fp14000 at 4 ohms

fp14000 is 4400 watts peak per channel, which should be around 3100 per channel RMS. However what I think he was saying is that the peavey's class D amp is nearly 100% efficient, so it's much more efficient than the clone's class H which is like 50%. so it draws much less power than the fp14000 to output the same amount on a 120v line, as you would be circuit limited rather than amp limited with a clone.

Also that is comparing 4 ohm to 4 ohm, the clone is not stable in 2 ohm stereo, the peavey is. so the peavey in 2 ohm stereo outputs more power than the clone in 4 ohm.

Here's the RMS power of the clone that cookie tested:

2600w / 2x ,4ohm load 10hz, thermal limit 3s, pulling 7.6k watts from wall
1600w / 2x ,8ohm load 10hz, thermal limit 15s, pulling 5.4k watts from wall
5580w / 1x, 4.6ohm, thermal limit 3s, 8.5k watts from wall
4050w / 1x 8.2ohm , thermal limit 8s, 6.9k watts from wall

Not to hate on actual test results, but these results lack information, mainly method testing, testing at other frequencies, burst output tests, etc. This is an amp, not a welder. Plugging it into an outlet and having it generate 10hz sine waves for X seconds tells only a small portion of the story. I'll see if I can upload some proper amp tests later that I've saved to illustrate what I would consider to be thorough testing. Also, are those IPR numbers from a tested amp, or just factory specs being reposted? So much speculation and assumptions lately.

Yeah those are just factory specs from the peavey vs clone's measured at 10 hz, so they can't be compared. Cookieattk did the only measurements so far of the peavey on a 10 amp line...

first test 450watts / 50hz
396w / 5hz
410w /10hz
440w / 20hz
445w /30hz
450w /40
450w /50

2nd test 990watts / 50hz
990w / 50-30hz
945w / 20hz
840w / 10hz
680w/ 5hz


at max gain / volume knob in theory should be 4v output from mini dsp i should have put a meter on this and included it but forgot !

1600 50hz
1240 10hz
1100 5hz


this is off a 10a power strip i had sitting around b/c the cord was too short and i don't have anything else at this house to use and didn't want to drive across town for a extension cord from my new house.

i will test this on a 20a outlet in a few weeks.

I think cookie was implying above in this thread is that unless you have a dedicated 30 amp line or 240v 20A, then the peavey will output more power solely because it is class D.

he also said

I see, thanks. Definitely not running 240 to the amp.

I ordered 5 at once, so here was the numbers....
$785 x 5 = 3925.00 + 500 for shipping = $4425.00 piad via paypal to sanway

Duty on 5 pcs = 252.34
GST on 5 pcs = 206.73
Brokerage = 59.00 + tax ( $7.67)
Handling fees = $13.14
is $992.77 PER amp ( this is calculated without Us dollar exchange on the initial purchase price and shipping fees... so I figure I have about $1000 into each amp....

Heywood is like me and was/is using amps for pro-audio... Which although is a different spectrum from you AVS guys, it still gives a good outlook of what the amps are capable of.. cool.gif

Since I mentioned it earlier, here is a link to a proper amp test of an FP14000. This is how to be thorough and have results that people can take seriously.

Yes, ask them for a UL rating and some warranty..............Just kidding
post #3288 of 4389
Long time reader, first post. I'm interested in buying a defective clone for a reasonable amount. 10kq preferred, but 14k also an option. Shipping to Europe, of course on my behalf and risk. Anyone interested, please pm me. I'm an engineer and a hi-fi enthusiast (av not so much) with an oscilloscope and a dummy load, so expect some interesting posts after the repair (crossing fingers).
post #3289 of 4389
Mine came in yesterday and looks nice. Much smaller than I expected. It kicks the Ultras up a notch for sure. Thanks for the find Notnyt.

Sanway says a tiny scroll with the UL rating is en route via courier pigeon.

I have been following this post for a while but never posted. I purchased 3 of these 14000 amplifiers Jan of this year. They have been used for live sound running on outdoor festivals all year. As I type this they are on a 4 day festival with multi national bands. The amp rack has been dropped from not being strapped in they are dusty they look like hell from being so dirty, they have played in extreme heat with no thermalling, they have been in and out of box trucks probably 30+ times this year and they are still rocking. I stay away from the internal voltage limiting as our external DSP's take care of that. From memory I believe they are limited at 120-130 volts. These things have had time on them from local, regional and national acts and surprisingly they are still going. They are powering SB1000z eaw sub cabinets and they can bring these to full excursion violently if used improperly. How long will they hold up I don't know but they are making money right now and that is all that matters to me considering the investment. I thought this would be helpful considering that is what the original amps were made for live sound not home theatre.
post #3291 of 4389
Good to hear they are robust when working properly smile.gif


They are just too much money for me when I don't trust the guarantee and have no electronics skills to fix anything!!
post #3292 of 4389
I would like to test my clone on this device. Unfortunately the price tag is a little high for one time use.

[EDIT]

Actually it looks like the FP14000 might exceed the capability of that amp tester.

Not sure if it would be nearly as thorough needed . Also, I would venture to say that those with the know how to perform actual bench tests would be able to do so for much cheaper than the cost of this device.

Seems like a pretty cool concept though.... At least for people like me without a clue...

Just finished up a 3-day gig and both FP14ks performed beautifully all night long without even breaking a sweat.. Each amp was on its own 50amp breaker coming straight from the main.. cool.gif

hey guys,
i have been a member on alibaba for something like 5 years but had never bought anything- i just use it to research clone companies and find monstrous subwoofers. well it turns out i may very soon be awarded a large settlement from some hanky panky the local law enforcement perpetrated agasint me. well long story made short is sanway has sent me advertisements to buy thier amps for years. this fp14k unit looks pretty beefy. this thread is now 110 pages and i have actually read thru a dozen pages to see what the hubbub was. seems several users have these in a home theature setup, i would LOVE to have an amp with this amount of headroom. so actual output is about half of what thier rms ratings claim? in the 6 to 7 kilowatt range? here is my question/problem-- my receiver has an rca subwoofer output? is there an adapter or converter to get my rca output into this unit? would the rca output voltage on my stereo even be enough to get this amplifer to full power? if these are designed for pro touring and stage use then they WANT double or triple the line rca voltage i can even deliver to it. could a few guys running these in thier home system chime in and tell me how they got signal to thier amp(s) please! i have access to line drivers from car audio (where my forte lies). from the fraction of pages i read seems a half dozen or more guys have these in use so if you OWN one please let me know your level of satisfaction as per its use in home. since i recently learned i may be gettin a huge settlement i have been researching for "big boy toys" and so since money will be no issue when it comes in i have been looking at subs like tcsounds 5400 and the clones of that. i will likely have either two pairs of those or a pair of the new designed 24 inchers on alibaba. the 24s claim rms handling of 5kw and so id probably run a pair with a single LG fp14k clone. as per warranty i will likely fork out for a squaretrade 3 year one for 100 bucks to ensure i get some good use from it.
post #3297 of 4389
consumer gear and pro gear work on different signal levels, but there is some overlap.

in many cases, a simple avr will have sufficient output for pro audio amps.

you can either measure the voltage or just give it a shot and if it is too low get a box to step up the voltage between your avr and the pro amp. they cost less than $50.

an rca to xlr cable is needed, but that only costs a couple bucks.
post #3298 of 4389
Post up the link to the 24" please.

Sounds like you have your $ spent before it hits the bank account.
post #3299 of 4389
Are there adapters to go from rca to xlr? Sure. Check on parts-express or amazon.com.

Will your avr have enough line level for the clone amp to hit full output? Maybe. I believe my onkyo 809 does, but many certainly do not.

However, most people do not plug an avr into a pro amp directly. We want some equalization control in between, and that can also solve the problem of wimpy subwoofer output on the avr. Search for minidsp or behringer feedback destroyer pro for solutions. You'll need rca/xlr adapters in that chain as well, but this is easy to do.

I would love to hear more about clone woofers, including perhaps testing. Intriguing....
post #3300 of 4389
i have some photos of the 24 incher in my old emails from august. i will hunt them down and figure out how to post them. its a BEAST with **5** 10 inch diameter magnets, hell my peronal photo on here for my account is the clone of the tc 5400 with 480 ounces of magnet .. ok ill go find that 24 now
