Brandon, no thoughts of using them to boost the low end?

Does it not seem just a bit ridiculous to even consider "boosting the low end" of a system consisting of 8x long throw subs? If that's necessary, or even entertained, I gotta think you're doing it wrong. wink.gif

Ha, I hear you but in my room I have quite the drop off - which is fixed by the minidsp - but it would be nice not to have to take away headroom to do that.

Scott, I know it is a shame and a waste, and at this point, I have not heard from the buyer so it may end up he is no longer interested.

haha, never say never. Everything sounds phenomenal right now, but it would be awful fun and pretty stinkin easy to build a quick dual opposed manifold in the back of the theater and have the RE's playing from say 40hz and down IB style. I just don't see a single epx4000 being able to give it enough juice, especially since previously I had one on each channel of the FP. but that was sealed, and more bandwidth.

I'll be pissed if you end up buying another Clone... Could have split the damn shipping with me!

From my times buying clones, the shipping was doubled when buying more than 1. There wasn't much of a deal to be had shipping multiples.

There is a natural rolloff that exists in most sub systems, either from the box constraints or reducing BL as the motor moves further out of the gap, or hardwired electronically induced rolloffs.
The PVG doesn't "always" help fully recover from that, and neither does boosting; but most of the times it does. If you have the headroom from 8 subs, you might as well put it to use.

repeat for output 3 into input 4....


basically you are "jumping signal" from input 1, into input #2, and the same from 3 into 4... that will input all 4 of your amp channels

Thanks! Will give that a try after pick up another cable. Just cut one of my last two spares.

Did you model it winisd with 99999 cu ft? I think they do pretty good with 1kw each. You wouldn't regret it. However, you have to draw a line somewhere.....just your choice where!

well, dude has about 3 hours before it is too late, and then I will have to do some serious thinking about this. If I did the IB, I would have to bring all 8 SI's to the same SW1 channel on the marantz, and then do sw2 out to the IB, and hopefully audyssey would be able to measure them together well enough...but the DCX can do some more if needed.

I definitely understand that part, and I think you misunderstood me. The post I was referring to mentioned possibly adding two RE xxx subs to boost low end performance of a system that already has 8 18s. I was just jokingly responding that if your 8 aren't doing it now, chances are, you're doing it wrong. wink.gif The implication being that 2 more aren't likely to help.

Its totally awesome watching those cones pumping back and forth with no air spring to hinder them.

MK are you still going fine with your new purchase?

And for all you that have the dedicated power point for these amps how did you get rid of the hum in the line?

I dont have one of these amps yet but when I used my dedicated outlet I have hum coming through my subs. When I use the power board that my AVR is on it goes away completely. Would a Furman power conditioner get rid of this hum or no?

balanced signal chain. I keep saying it. worked for audiovideoholic. a conditioner will not get rid of the hum.
post #2715 of 4398
Thanks not. I only have a RCA out to 1/4 input now. Works fine for now but when I get a bigger amp, such as the clone, I will use my dedicated socket. Does the AVR need to have a balanced out or will a converter do ok?

You can use the chassis ground on your avr as the ground in the balanced connection.
post #2717 of 4398
Yes, I have watched a movie every night since I installed it at reference and the bass at 9 dBs hot. Man, 9 dBs hot makes many movies a much better experience! I know it is not the accurate way but it sounds so much better to me, besides I want it better than imax and it is. These amps really are powerful! I had a ground loop adding the amp as well and grounding works fine.
post #2718 of 4398
Oh, one night I was away and stayed in buffalo and they had a big IMAX there. I took an elevator to the 4th floor. It was a 5 story screen. I would say it was as loud as my 10 dBs below reference. Best visual experience though and the smaller IMAX had much more bass.
post #2719 of 4398
Thanks MK. They just needed to add four of the DSL TH221's. biggrin.gif lol

I still am thinking about adding one of these 14K's. Just have to save for one again. Nothing comes close and powering my 21's need a lot of power in 5cuft.frown.gif
post #2720 of 4398
Yeah, this IMAX is a 5 story free standing building connected to the othe theaters by a long hallway so the bass can be turned way up. This was the first time I experienced the bigger IMAX. The sound and picture was better however just not turned up loud enough. The funny thing is the way I set my screen up in my room is the same way as this big IMAX and you get the feeling of falling into the screen. Madaeel told me that the big screen like that makes it more like being there and he will do the same thing. Basically I just have a screen big enough to go from floor to ceiling like the IMAX. So imagine the front wall of your room and then put a screen that will fill it in! I only have 20 inches on both sides of my screen with no room above and below.

Just saw an ad with someone trying to sell one of the 10000Q Clones for $1500 ! You can buy two for nearly that right?
post #2722 of 4398
yes

Depends on where it is located: Barrow, Alaska or Ushuaia, Argentina?
But yeah, you could probably get two for 1800-ish.

Nice theater, me and the 7yr old saw the hobbit there .

Ebay has someone selling them for about 1500 and say that have a one year warranty for Australia. I like the warranty part but Callahan motor parts have a warranty also.(Tommy Boy Movie if you dont know)

Recieved my second Clone yesterday.

Here are a few pics.

Double boxed.


Bonus item! Fancy Calendar.


This kinda bugged me. Different power cable vs. my old Clone.


A perspective shot of the gauge difference.


Another perspective shot of the power wire gauge difference. New amp on top.


I've yet to get into the internals, but I'm expecting some glaring differences as well.

WTF ever... I guess just as long as it performs, I shouldn't care...

Hope to have it powered up by the weekend or so.
post #2727 of 4398
If it's any consolation, it seems the new amp cord looks beefier.
Maybe the internals are beefed up as well? biggrin.gif
post #2728 of 4398
I like that new amp power cord. Is this 120vac or 220vac version?

120vac version. Here is the email from sanway.

Glad to know you want to order one FP14000 and one amplifier board. The total amount for one FP14000 and one amplifier board send to US is USD 726+USD138+USD120(shipping cost by FedEx)+USD34.44(3.5% paypal handling charges)=USD1018.44.

Our paypal account is: sales@china-sanway.com. Please inform me after transfer, so that I could deliver your order upon receipt of the deposit.

Besides, I will send the FP14000 with 110V version and American Power Plug, which can operate from 65V to 135V voltage, OK?
post #2730 of 4398
Why has the cost gone up now?

I thought the cost was about 920 for me to get one. I may have to ask him again. its been a while since I last spoke to them.
