Thank you everyone ,
First I want to simply my set up with 2 amps, but I was not sure which amps are suitable for 6 Dr250 3 per side, according to DJPhatman does not recommended more than 3 Dr250 per side so I take his advice and go for 2 amps , For the bottom T48 (2 loaded with la15 and 4 loaded with 3015lf) which an decent amps got enough power with some head room if I want to add 2 more T48 ? I may have to get risk of Xti 4000 and get one with out Dsp since I 'm using Driverrack pa . Would Ipr 5000 do the job ?
Thanks again.

Ok, you've decided to take DJP's advice for the DR250's.
Unfortunately, the same principle applies to your subs for the bottom end.

We have tried to explain; You might find an amp that will run the 4 x 3015lf loaded cabs on one channel, but you shouldn't do that, for the same reason you shouldn't run 3 x DR 250's per channel.
And you should run the lab 15 loaded cabs on a different channel or amp to the 3012lf loaded cabs.

You might simplify your system to run with 2 amps, but you will run them hard all the time, and they might not last long. The worst possible thing is for a failure to happen mid gig because you're always running your amps hard and they decide to give up.
When you start putting together as many cabs as you have, you have to spend the money on amps to run them the right way to...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...

Mino00 I stated that you should not run more than a 4 Ohm load on an amp channel. I would never recommend 3 DR250 one 1 amp channel. Ever. I said you could, using the RMX4050, put 3 T48 on a channel, since they are 10 Ohm each. These are the facts, mino00: you are trying to get past simple physics. You need 6 amp channels. The only way you are going to get that is to use 3 2-channel amps. 1 amp for 4 DR250, 2 on each channel, then 1 half of an amp for the other 2 DR250s, and the other half for the T48 loaded with the Lab15. Finally, run the other 4 3012LF T48s one the 3rd amp. Any other path is at your own peril.

Thank everyone
I'm learning little about ohm laws applies to speakers, I thought bigger amps can pull more speakers , so what your guy think between the listed amps are reliable for my set up 2 Gx5 for the top , 2 Gx7 for the sub or 4 Ipr 3000 ?
Thanks

Henry, if it were me, I would go for the IPR. Just for the weight advantage. 3 IPR = 21 pounds = FTW on load out! Even if you add a 4th IPR, that's still only an extra 7 pounds! :shock:

Do you have a DSP, such as the dBx Driverack or the Behringer DCX/DEQ combo? If yes, get non-DSP amps (less expensive), if no, you can get the IPR with DSP, but I have no experience with the Peavey built-in DSP.
