Can someone suggest me an amp for these?

@ loverocket, that amp pushes 700 watts per channel at 4ohms, should be just enough. For $200 more The GX7 runs 1000 per channel and would be ideal.

The extra $$ you spend on a QSC makes a difference a few years down the road when that Beringher craps out. Buy quality or buy twice.

While that was true a couple of years ago, behringer really have stepped up their game with their new releases, and they're darn reliable.
OP will probably use them for mobile parties and such. Having a lightweight amp really helps.

I don't see any proper test results at 4 ohm.

Here are some actual results from Tools4music:

Peak power 20ms/1000Hz
8 Ohm 2x465
4 Ohm 2x870
2 Ohm 2x1700
RMS (sine wave))
8 Ohm 2x312
4 Ohm 2x600 (2x375 after 3 seconds)
2 Ohm 2x1176 (2x750 after 1 second, protect after 5 seconds)

You'll need the iNuke 6000 for those 1000w JBLs, which is just 2x 3000s bridged in the same box.

Ok, can't argue with facts. I do however know, from personal experience, that 3000's can kick some ass.
In a club i'm resident at, they are using a battery of 10 nu3000s and 6 6000s to drive some pretty big boxes. And i was there when they were still testing the system. One amp and a pair of mains were loud enough to hear the music outside. And it's a pretty big place, too

I know it's 700W @ 4 OHMs. You said "match the continuous power which is 500W.

>

I didn't say that. I would say something like this:

"speakers are rated after testing with a continuous signal but music by its very nature varies in volume so speakers can easily handle short term peaks without overheating. Since the whole point of a PA is to give an undistorted sound and amp distortion sounds horrible it is better to have plenty of power in reserve. It is ok to have headroom of 6dB which is 4x the power so you can have a 1200W amp running a 300W speaker so long as you don't go into clipping. This is why almost all PA amps have clipping indicators, if you are running an over-powered amp into a speaker you really must not let the clip light come on. Most of the big hire companies compromise with 2X the rated power."

I am about to purchase these speakers, but I need an amp. I know very little about amps, but my buddy sais I will need an amp that can do 2 channels 500 watts @ 4 ohms. there are about a million and a half different amps on amazon and similar sites of varying brands and prices (quality?).

Could someone who knows a bit more about this suggest me an amp that will push these as far as their potential (getting everything i paid for)?

Thanks!

Just want to give you a little heads up. Those speakers will sound awesome but don't expect a lot of bass from them, main cabs are really only designed for 80hz and up. I also hope you aren't planning on moving them around much because it's going to be a bitch. If you are planning a portable system you would be much better off with a sub + sat setup.

As for power ratings on amps, I have pushed my ev eliminators to excessive levels using a hafler TA1600 (about 75wrms). The spakers have such a high sensitivity that even a few watts gets them into the 100db range. Focus on getting an amp that is going to be reliable and if you get serious you will want a backup.

Hm, yeah I don't know a lot about speakers, just people keep suggesting those two. And are you sure? two dual 15" subs are, well just that and I can't imagine they'd be crumby.

What would you suggest? I can't imagine trying to plan out my own sub and all the other speakers stuff to combine to create a good sound system.

And also guys, I'm still a bit unclear haha, will the 3000 cut it or no? Everyone keeps going back and forth on that.

[makar1]

No, the iNuke 3000 will not cut it for those speakers.

Go for the iNuke 6000, QSC GX7, or similar.

Those are a 2.5way design, meaning that the woofer on the bottom has a lowpass filter that limits it to i believe something around 100hz, therefore acting as a proper sub when placed on the floor dual 15's can fill a room no problem

After some thinking i changed my mind and agree with you, really thought the 3000 was enough :P Still, qscs are heavy...

So they will have a lotta bass?

Ack, I'm trying to learn all this speaker stuff, but there is just so much I don't know/understand.

It's like I have this money (I'm willing to drop like 1200 maximum), and I want a badass set-up, that will be at least moderately portable, and not a massive bitch to set up.

So.... Both Jbls that require 500watts @ 4ohms require a 6000 watt amp? Is the 500 watts @ 4 ohms describing what the minimum is? Or what you'd need to push em as far as they can safely go.

Because that's what I'm looking for, I feel like if I'm going to invest in some speakers I at least want the ability to push them to their potential even if it's not always needed (I know all you guys would agree it feels awesome to have all that power)
