Seven Bryston 28B-SST mono amps would cost over $50,000, weigh 644 pounds, and put out 12,600 continuous watts into 4 ohms. Of course, you could get something comparable with four FP14000's for $3,000! Probably wouldn't sound quite as good in the midrange though.

No he had the 7 mid/tweet and 7 bass towers, 1 set per channel. 14 x 28b-ssts, 1 mono amp per tower. I though thats how they were no? I never saw them before that guys place, other than online. To be honest, I had never even heard of them before that day. Well none the less thats what he had. He was quite well off as you could tell lol.
I've done over 50 pro installs and it was in the top 3 for sound. It wasn't crazy HT loud but just all around great sounding. The best part was the guy was using integra 80.3 as his processor..... strange for that high end but I had seen that more than once. The 80.3 is pretty damn popular. I was happy since I have one as well and knew the menus inside and out. I've been on the lookout for a set ever since!

I've only had mine for 2 weeks, so I can't comment on the longevity. However, the construction quality inside looks good. The circuit boards seem well made and are marked well for future troubleshooting. The solder joints all look good. The metal case seems sturdy enough and the fit and finish is very good.

I've got mine on regular house wiring with a 20 amp breaker. On the same circuit I've also got my preamp, cd player, and two other mono amps. So far it hasn't blown the circuit breaker. But I'm playing music with it, not playing home theater sounds, but the music has plenty of deep bass content (try Bela Fleck - Flight of the Cosmic Hippo or Dallas Wind Symphony - Fiesta) It easily hits 103db on some very inefficient subwoofers without any problem. I'm measuring this 10 feet away from the speakers in a pretty large room that is open to the rest of the house. I haven't hit clipping yet, so I think It would go to at least 106db. I'm sure it would be better if the FP14000 was on it's own separate 20 amp breaker, but it's working fine for me as is.

Haven't had an issue, running on 120v 30a
post #3095 of 4394
I've had both of mine for almost 2 years, no issues. 120v 30A.
post #3096 of 4394
little less than 2 years and rockin hard. 120v 30 amp. I think those of us in the dedicated 30a club have had the most success, but that was kinda drawn out from the very beginning by Not, so it isn't like it's new news.

28 x 34 x 12. A big room!

I've got 4 x fp14 clones running on their own 120v 30 amp lines. I abuse them all the time, no problems here.

the 2nd pic watermark even says china-sanway.com. the same pic is posted in their main page. bet they import the amp from sanway, increase the pricing to cover for warranty purpose and sell it as their own.

post #3101 of 4394
Seems like after two years, this clone is a pretty dependable purchase ? Are there any lingering issues at this time. I've been watching this thread stay on the front page for two years, thats quite a feat !
post #3102 of 4394
Has anyone used one of these clones outdoors running off of generator power? If so, how well did it work?

Thanks.
post #3103 of 4394
Hello friends, I have a problem in my amp FP14000 Clone, saw in this forum that several had the same problem since I changed several pieces, but have not found the cause of the problem.
  When I turn on the amp it is oscillating (on / off / on / off / on / off) as the video: http://www.youtube.com/watch?v=uHRvz1wuh-Q
Could someone help me solve the problem?

Thank you!
post #3104 of 4394
did you contact sanway? It sounds like the voltage regulator needs adjusting on the power supply board. Don't attempt without proper safety precautions and instruction.
post #3105 of 4394
I still haven't fixed that damn issue...

I just imagine it's doing some push ups for a quick warm up, then it's good to go for the rest of the night. Plays fine for me other than that...

Hi guys, i dont usually post on this forum but this thread convinced me to do something kinda crazy and use the FP series to drive my first sound system and so far, even though im still waiting for three, i couldn't be happier biggrin.gif

Thats great man! It's hard to judge reliability and performance by forums because

Just received my FP10000Q and I'm excited. It was very well packaged (single-boxed, but nested in a sort of crash pad layer) and appears to be working fine. First impressions: it sounds very much like my dyson vacuum. I scoured this thread but found no mention of specifics for fan mods to the 10000 (I don't think it matches the 14000). Does anybody have detail or part numbers?

If not, I will forge ahead and post my findings, but I want to give it at least some trial period to ensure it works before tearing it apart.
post #3110 of 4394
it is the same fans as the 140000 in the beginning of this thread

Just a heads up:

I've been measuring signal chain roll off, including amplifiers. I'm now using the flagship Oppo player as player/preamp straight into my signal shaper for the subs. That combined response is the gold trace. My signal shaper (SEQSS) is analog and I've been able to eliminate DC offset with virtually zero roll off, so the roll off shown is basically just the Oppo.

The Clones are marked on the graph. The K-12000 was sold to me as an FP9000. The difference is that the FP9000 has 8 caps in its reservoir and the K12000 has 10 (like the FP14000, but the 14000 caps are 3300 uF and the K12000 are 2700 uF).

BTW, I've had a pair of K12000 amps for 3 years without incident.



As you can see, the 2 Hz spec Sanway and all the other vendors claim is not the reality. The FP9000 and FP14000 are recent purchases (not from Sanway) and show the response rolls off almost 2 octaves higher than spec and is steeper than most any other amp I've measured.

Using something like the Onk AVR into a PEQ (DCX, Mini, etc) then to a clone will net a roll off that's down approximately -16dB @ 3 Hz. Using the Oppo into the SEQSS into the FP clone is much better, but if the clone response was what it's supposed to be then the roll off would become irrelevant.

Anyway, the FP 9000 and FP14000 are shown in the graph above (dashed red trace), FWIW.

Different clones have different specs. You say you didn't purchase yours from Sanway. Are they using the same components as the sanway amps? Have you disassembled to verify? Where did you end up getting them, and the k12000? Are you assuming the FP9000 you were sold is a K12000 strictly based on the number of capacitors? There seems to be a lot of assumptions and vagueness here, just trying to clarify. We all know Sanway and the rest mostly just copy the real Lab spec sheet, however not all clones are the same, and making assumptions based on different equipment is not very scientific.

The pair of Sanway FP9000 amps are not FP9000 amps. They are K12000 amps with FP9000 front panels. It's marked right on the boards. I've told you and shown you this before you bought your amps.



The front panel can be put on any clone, so you have to open it up to see which one you actually got, which in my case goes without saying. None of them is flat to 2 Hz. Show me one that is flat to 2 Hz and I'll have something more than your rant to add to my data.

I'm not making any assumptions. I'm reporting what I've found from buying a dozen amps from several suppliers. You bought 4 FP14000 amps from Sanway and that's your (and as a result, most everyone in this thread's) total experience, so I don't understand your post.

Take the data or leave it. No skin off my teeth either way.

I've seen at least 3 different clones from different manufacturers. I wasn't ranting, I was just seeking clarification since you're comparing a non sanway clone to another. I'm not making any claims that the sanway clones are flat to 2hz, but was just seeking clarifications on which clones you used for this and if they had the same components as the sanways.

Just an update on my bad amp. After a month, I finally got the repaired power supply back. Looks like they replaced a bunch of stuff. I got it all installed, and still no dice. It's even worse now. I flip the switch and nothing. the power led doesn't even light up anymore. I checked all the fuses and they're good. When I flip the switch, 120v is being sent to the power supply. But that's as far as I've gotten so far.
post #3117 of 4394
Hi All,

Well after my iNuke 6k DSP lasted a mere 3-4 weeks before dying (I believe it suffered the fate of the faulty power diode problem) - I decided to take a HUGE leap of faith.

Sadly it's almost the same reading for quiet a few buyers here.

Pre-Sales communication is great and responsive. After a few days of emails, we agree that I want the FP10k 220V unit and they will install the 'quiet' fans.
The unit arrives in 4 days after shipping from Hong Kong and not in a good way.
How they still shipping a 14kg metal box without any safety padding is beyond me. It would surely cost them cents to add some padding to the unit.
Luckily the the double cardboard box provided some basic level of protection and only the back of the unit took a couple of hits.









The fans had not being changed and something fell out of the unit when I opened it.






I am now waiting to see what JT has to say.... Day two.

The good news
It works (touch wood / thank the gods of the old and new worlds)
Got v4 of the main board
Got v3 of the other boards
MUCH lower noise floor with the FP10k compared to iNuke 6k. I would get a hiss from the drivers with the iNuke on idle. Dead silence from the FP10k.

Current Setup
Running on a dedicated 4mm wire run to a 30A 240V breaker. Power in my house is around 238V.
AVR -> SVS AE-EQ1 -> Y adapter to dual RCA-XLR adapters -> FP10k -> Dual Opposed Dayton RSS460-18

Running Channel 3 and 4 off the FP10k to each driver.

Current FP10k settings
Gain 41db
VPL 121V (translates to 1740W @ 4Ohms on all channels) - Should I drop this to 101V (1250W @ 4 Ohms) ?

With these settings and using the AS-EQ1 to level match to 75db. The front gain control are set to 9 o clock (25%)

Can some one please comment on this as I'm not entirely sure how to setup the input gain properly?


Proposed changes and updates
I really need an EQ for my room and plan on getting the miniDSP as it appears similar to the iNuke DSP that I used with good success. I will then probably bypass the AS-EQ1.
Is anyone running the same and what changes should I be aware of regarding gain setting.

Should I bother getting a Art Cleanbox Pro to use after the miniDSP?
Pros - 4db balanced inputs into FP10k
Cons - Another device in the link.

Reason for the 4 channels is later this month I plan to start a DIY build of 100L box for a LMS-R 15 that will go on channel 2.
post #3118 of 4394
My just ordered fp10000 was packed similarly and came out fine. As far as that extra bit of solder, I would say shake out the extra pieces and enjoy the awesome performance.

Re: gains, I have mine set to 41 db based on my trolling of this thread. Seems to work just fine. My voltage limiters are maxed as well, but maybe I just live dangerously. If I start bottoming subs I might trim that back. Right now, with a room eqed pretty flat playing mostly music, my ears are bleeding before the subs are doing much work.

I'm planning on getting a FP10KQ to run my LCR down the road. I've heard Bassthathz had good success using one for his mains

Anyone else doing the same?

Not just good, it is now my new reference amp for LR treble, as of last night.

I hooked the Oppo 105 directly to it and it beat the SQ of every other amp I have tried to date (beat Rotel gear and seems on-par with Classe stuff).
$1500 vs $6000 is huge savings and it also uses 4RU less rack space (while producing even more power).

I have 10,600watts going to my LR mains now (quad bi-amping with clones and crowns as quasi-"mono-blocks").

My tweeters and mids drew enough power to faintly light up the -4db lights (a solid 210 Watts RMS x2 FOR F%#$ TWEETER CONTENT! Unbelievable!!!).
I had to disable my two 21's to make that happen though, for now...

I put my ear directly up to the tweeter, not a peep. Probably has to do with the ESS Ref DAC noisefloor... wink wink wink.gif

I will never go back to using AVR's (haven't for years); and I'm now phasing out my 4000watts of "Hi-Fi" amps too and will be replacing them with clones eek.gif
