what are you using it for? what other gear do you have, sources and mixer? effects? what SPL are you looking for in what size room? are you looking for a system to make noise or do you want a system that will reproduce music ( quality of sound)
 
2RU models: RMX 850 | RMX 1450 | RMX 1850HD | RMX 2450

it's for a DJ setup. I just need clarification from a pro if the setup is good for single 2RU system or if seperate amps are recommended for each the sub and speakers to be driven.

I'm firm and just takin' feedback from which recommended amp to power it all. just tell me if the watts match up.
-thx

 
if you want to run the system in stereo you will need 3 channels of amplification, unless the sub can handle 2 speaker level inputs( which it appears in the specs in can not), but this is not recommended as you will have little control over the volume and freq. the sub handles. we really need more information to help you.

2ru just means 2 rack unit.
 
you might want to shoot Rubycon a quick PM, I think she works with this sort of stuff everyday.

In the end, the speakers you chose will limit you. Larger venues will require higher power handling and larger speakers that can output. 98dB/1W/1m with 90W power handling seems to be sufficient for at least medium sized venues, but again, might want to check with Rubycon on this.

fvck, I thought this one had crossover technology. ur rite, I do need sep amps. thread is done.
 
I might perhaps recommend buying an active crossover - Behringer sells some decent ones for not too much - and two amplifiers: One to run in stereo configuration, and the other to run bridged into the subwoofer.

If you're feeling handy, you could build yourself a Selenium horn subwoofer and a pair of 12" coaxial mains using the PE buyout drivers (Eminence Deltas, apparently?). Add five channels of amplification and a Behringer DCX2496, and you're set.

thx, I looked at the RMX 2450, and it has bridging and multi output selector switches for satallite and subs.
 
Don't bridge an amp unless you MUST. Particularly the RMX series. Now if you're talking power light they do fine. 🙂

Remember bridging provides 3dB gain where adding another cab can boost the gain far more especially with cabs that couple well - into the lower frequencies where most of the power goes.

The Bee-ringer x over is decent for the money and good to learn the basics when you're ready to move on.

Also you always want to run two subs minimum! They couple nicely. The Peavey is entry level, their QW line is more suitable for live sound/extreme DJ but it really depends on what your goals are too.

p.s. We don't call 'em sats and subs, that's homespeak. 😉
