Bad Boys from the big Boy.....
No problems with speakers now Tyrone...
Congrats...now build a cart for those.....lol

Yep!!!
There were carts for the four top speakers, but nothing for the subs. I'm going to build some very soon.

At least you'll have something to go along with your bad case of ....
Hey! I'm taking my shots for that, and should be cleared up in a week or two...
Actually I meant a mobile dj station so you can use them on the deck at your club. That'd be a sight.....
Tyrone,
Well you can honestly say it would be very rare not to have enough speaker power at your disposal.
What are you going to use to power the setup?
I'm guessing they are either Mpro's or an older line.

I was curious too but hey PAT/CHRISTINE whichever one you are lol split that it adds one more member towards our 200 for Christmas goal. Glad to see you here dont be such a stranger its getting better and better day to day. Lots of good info here now! Mike Early and I have even made peace.

They're all SR...
...and I have three Crown K2's to power them all (15,000 watts total). I'm waiting for a warmer day to test them... it was 5 degrees here today BRRRRRRRRRRRRRR.

You could turn those Crown's on to stay warm with!
We've got the snow and cold going on here in Colorado right now, too!

That's a lotta power
I hear these numbers and many of you say “Wow”. Usually I’m incredulous. Believe me Tyrone this is not to put you on the defensive by any stretch of the imagination nor doubt one of my favorite amp company’s specifications.
Always remember that Power Out = Power In - Inefficiency (losses). 15,000 watts means you would need over 125 amps in (we’re talking RMS here). That is as much as the total available in most small homes or enough to run four electric clothes driers (with the cords that look like a water hose) simultaneously or the total amount available on six separately circuited receptacles.
This is just sort of a reminder that while the amps and numbers are impressive you still have to plug them in to get the power that comes out the back. One nor two 20A circuits will not cut it at this level of power.
Well, yeah, OK, WOW fifteen kilowatts.
Jes** H CH***T! I missed the picture earlier in the thread. Tyrone are you F'n insane? Did you buy a semi along with that rig to get to the gig?

Balanced, while those numbers are impressive they are also incorrect. The K2 draws a mere 10 to 12 amps. In a typical setup not pushing hard all three amps and all other gear in the sound system can be run without a problem on two 20 amp circuits.
Not to say that three K2's is enough power for all the speakers he has, (he needs 1 K2 for each sub alone to reach that subs full potential)
I have run a 20,000 watt system on a simple 80 amp circuit before.

You've got to be kidding me!!!
Very nice Tyrone!!!
I forsee a DIY distro article from Tyrone in the near future.

Tyrone,
You have a really great system!
But I think I need to correct some of your misconceptions.
1. you don't have anywhere near 15000 watts (although that is what the speaker system requires), max all three K2's are capable of 7500 watts. 500 per side at 8 ohms, 800 per at 4 ohms and 1250 per at 2 ohms. The K2 is an extremely efficent amp and should serve you well, but you really need more power for the full system.
2. While I don't have the specs in my head for the JBL's you bought I bet I won't be far off with these guesstimates. The 18" drivers in the subs will have a contiuous rating of at least 300 watts, program of at least 600 and a peak rating of at least 1000 watts at 8 ohms. Now each box carries two drivers so each box is 4 ohms and needs at least 2000 watts just to match peak rating.
3. Each K2 in stereo is going to deliver 800 watts to the box, divided by two that is going to net each driver 400 watts or well below the program rating. So for four sub boxes you will have to use two amps just to limp in with barely enough power to even warm up voice coils. running 2 per side for 2 ohm operation will net you even less power per box at 312 watts per driver you barely make the continuous rating and certainly don't have enough power for a clean signal and will clip on every bass note below 60 hertz.
4. Again I don't have the specs for the JBL mains either but let's say they are rated 500 watts at 8 ohms program. With the addition of the horn driver and passive crossover power loss the driver will be getting around 400 watts a little low but serviceable. So for power to drive these units you need one K2 for each pair of main boxes.
To properly power this system you really need 3 more K2 amps (A little hot for the subs but controlable).
However I could be wrong on the power handling capabilities of the JBL speakers but I will bet a dollar to a donut that I am close.

A tad less
Actually you’d have to de-rate a bit more. It is a bit disappointing that Crown’s using an IEC type rating (@ 1KHz) rather than an FTC type rating that specs 20 to 20KHz.
Well 4.5KW is a bit of a letdown when coming from 15KW.
