I was going by Hawkins post and Sanway's website. It provides some info, but to be honest, and I'm not familiar enough with electronics to clearly identify what is the basis of "their" design for the P1800. Thus my question.

Bosso, I have been meaning to PM you on this matter but since you showed up again I figured I would ask it here.


I have got two arrays of gen 1 maelx's, I can either get the cabs to 2 ohms or 8ohms based on my VC config(which are 8ohms per VC). I've got the two cabs wired in series to 4 ohms with a ma5050 bridged. I have been looking at these amps but I really don't want to risk frying my drivers and playing around with winisd and 9000 watts it looks like I over run the xmax pretty early(20hz) and then hit xlim just below 5hz.

Basically what I am wondering and I think other people are wondering is aren't we running the likelihood of killing our drivers in sealed configs or does the air suspension basically save the drivers?

1 Chinese yuan does not equal 1 American dollar. According to XE.com the Yuan is worth 0.153877 USD. But because the Yuan is pegged, the ratio between the the USD and the Yuan remains the same as the USD goes up and down. I.e the value of the Yuan (i.e. the ratio) does not change, but the ratio is not 1 to 1.

Thanks Hawkins, I was not aware about that aspect of the culture, very interesting. Also, thanks for looking into the P1800...it seems too good to be true (or should I say good?)...at least from this side of the pond.

Notnyt, you 'should' be able to get customized fans if you ask for them. If working with a factory, it shouldn't be a problem, just be specific about how and what is the best way to customize and achieve similar airflow.

Bosso

So what freq do you aim for then in order to limit excursion, knowing you probably 3hz or 0hz. I don't have the winisd parameters for the tumult so I can't play around with it now.


That kinda leads me into my next question, looking at chaz's ratings for some of the amps he has tested, what do you believe these 14000's are capable of delivering in watts? Nots running a 120x30amp line so the most watts he can put out is 3600 correct even switching over to 240 gets us to 7200. So where does the extra 7k of watts come in, is it banked in the capacitors?

Make sure you click MAX on that chart to get long term view. Note that the peg is no longer fixed. The Chinese allow a slow stepped change in yuan value. It should be worth far more, and sadly, our dollar worth far less.

Limit excursion @ 0hz ? lol

About the 14kw rating, it's a magic trick called false advertising afaik

Lab-gruppen also advertise them as 14kw with a 16a @ 240v current draw limit. Despite the false advertising these amps are some of the strongest money can buy, even as clones.

I spoke to him at length.
I think its a factory. I called some competitors and they confirmed this.

Not---You can get the fans customized. Just tell him what you think is best.
For a group buy, we can get any of his product line at wholesale price(even better price). Also, for the prices I listed earlier for bulk buys, the bottom wholesale price can still be negotiated, probably about 20$ more max. Also, it doesn't have to be the same product, it can be different products mixed together to achieve large quantities.

For AB, they can't get the watts that high, which is why the p1800 is class H, but the p1200 is class AB.

I spoke to him about the amp not muting under high temps. Thats what happened in the 2 ohm, 2 channel test, right? Well, he said that the amp should mute itself when it gets hot, but he wasn't associating that with the vpl having a problem.
He then said, it can do 2 ohms, but don't do it for long and heavy periods. Best to run it not at 2 ohms.

There are lots of companies that will sell the same amplifier. They do not build them either. They're all in the same neighborhood in Guangzhou. Here are some of them...

Guangzhou Gisen

http://gisen.en.alibaba.com/

Sanway

http://sanway.en.alibaba.com/

Guangzhou Ho Young

http://hyaudio.en.alibaba.com/

La8 Green (ya gotta love this name, eh?)

http://image.made-in-china.com/2f0j0...er-FP1000-.jpg

Hy Pro Audio

http://image.made-in-china.com/2f0j0...FP-10000Q-.jpg

Guangzhou Hao Yang Pro Audio Manufactory (they sell BOSE as well)

http://www.topfreebiz.com/company/23...anufactory.htm

Or, you can go to China Department Store and buy an actual Lab Gruppen tagged FP+ series amp, complete with on board Nomadlink, for $1600 + frt

http://www.chinesedepartmentstore.co...oducts_id/8541

Same goes for Crown, QSC and many other brands.

So, asking about any other 'Sanway amp' is an impossible question. Like myself and not, you just have to ask your questions of them and, in the final analysis, order one, tear into it and test it. It could be virtually any amplifier with a different face plate on it.

Bosso


Sorry, let me clarify a little here since I've done this research recently.

Gisen has a completely different unit. They use aluminum heatsinks colored like copper and smaller capacity capacitors.

Ho Young, and HY pro audio are the same company. They will send you the same specs and pictures that Sanways sends out and claim its theirs. They make speakers, and just resell Sanway's amps at a higher price.

I don't know about la8 green or Hao Yang. The pictures la8 green are using look to be of an actual LG amp with nomadlink photoshopped out from the back and the logos changed.

The link from "chinese department store" is the Gisen unit, or the same one they assemble. At least the pictures are. They have some real LG marketing pics in there too.

Either way, the ones I have from Sanway seem good so far. Can't really complain at this price anyway. I may add one or two for myself to the next order to keep as spares though.

It's the rating for burst power, not sustained.

I'm working on figuring out what is and what works well enough. I have a bunch of fans getting delivered Monday to test with. I think I've found a good 80mm, but I need to test still.

i bought my projector from a kid in japan who ran across the street and bought it at a shopping mall and then dhl'd it over here...but some of these chinese guys are hilarious.

from the hyaudio.com website. i'm not kidding, it is actually on their homepage.



his apartment is on the right. his bad photoshop "distribution center" is on the left complete with a purple delivery truck!

What 2 maybe 3wks.. Based on Bosso's comments I think it would be advisable to hold off on a GB just yet as many may not have the disposable income to "buy spares" when their units bake. I commend you offering to back this but I think it may be in haste to jump right into another order.

I'd agree, but people are bugging me to buy them, so an order is going in this week. I don't know if I'm going to do more than one as it's a pain, but the information is all public if anyone else wants to organize one. I have the cash to front this at least. Since I'm ordering a good amount, I'll have spare parts to deal with any issues. Anyway, not forcing anyone into anything. I beat on these pretty good when I got them. I'm very impressed, but we'll see how they hold up.

When I spoke to him about the fans, he said something about having to import fans from taiwan to get something better.

Can you elaborate on what happened with the Harman products?

But, as not will attest to, the Chinese also love to change parts specs and manufacturers with no notice, including a recent switcharoo done on thousands of Harman products to black market components (according to a reliable source), so I don't know what Sanway is selling these days as far as what fans are being used.

Bosso
Exactly the problem. I know a few people and have read enough stories of prototypes and 1st runs being to spec., and then the old switch-a-roo. A penny saved is a penny earned. We all know how that turned out for the MFW amps, and the latest being the new Peavey amps with a years worth of delays and finally shipping re-worked and re-boxed from the factory. It's sad when you hear about large companies that don't even bother to employ a couple people to monitor the production of their product.

Anyhow back to these amps, do you think the Sanway's are the LG factory side-selling or are the internals different? Have to say it is a hell of a lot of wattage for the money.
