One step further....

Jeff your wisdom on running bridge mono per cab coupled with a major upgrade in drum mics made a huge difference...

in the earlier scenario I admitted facts about the size of the venue;

with a budget of 1000 dollars; would u place a dual 18' cab center stage or run an additional 18 on each side? I am running the bottoms mono out of a Peavey vd 2/3/4 with a Y cable on the sum output... the QSC 2450 powers stage left dual enclosure while the Europower 2500 powers stage right

I have seriously thought bout just throwing a dual 18 in the center...throwing the QSC on that enclosure; and purchasing another EP 2500 and cab for stage left.... we could still use some more thump... HOWEVER we acheived very nice mixes on all of our bands, I just like havin some extra bling in da bucket; proverbially speaking

what about the low output of the Xover? u def get signal degradation every time u split a signal.... what is the correct way to split this yet a third way?

possible scenarios?

any input is welcome!!!

You should try to cluster the subs with the mid-hi cabs or you will end up with an imbalance of subsound and even some time phasing problems.

If there are no mid-hi cabs in the center, I wouldn't put any subs there either.

The crossover output should handle 3 power amps, but beyond that, you may need a 1xN splitter/distribution. You should be able to use another Y cable to get the signal to the next amp.

What model and how many mid-hi cabinets are you using?

we are running dual 15" with horn Yamahas on each side. The room must lend itself well to these cabs, cause they sound great. I have no power issues with these at all...

I saw LHSL run subs in the center of that stage last November, along with prob 25000 watts of power, at times I found it to be unsettling cause there was too much thump...

it lost some of its effect after awhile as it made me tired listening to it at that volume

I had worried about it sounding out of phase....

Those speakers and subs should match up well if they are properly powered. You should have about 1000 watts rms on each 215 cab.

After looking at the CW218 manual, I found that the RMS rating is only 600W and the "program power" is 1200W. This is all very deceiving to the typical user and I wish these companies would all report the friggin' RMS power as the standard power rating so that there are no miscommunications.

You must be very careful using those 2400W amps to make sure they don't exceed 2400W or you will blow a voice coil. Since the RMS rating is actually 600W, you only actually "need" 1200 watts on those subs. However, 2400 watts rms is the absolute optimum power amp for them, but like I said, you must be very careful not to exceed 2400W.

You might bet better off spending money on a lower cost speaker management system like a dbx DriveRack PA and a reference mic. Also, make sure your sub crossover frequency is 90Hz.

I actually am running them at about 60-70% power just so I dont cook the voice coils; I have plenty of headroom with the amp

i was aware that 2400 is peak on those cabs
