Electro voice elx passive


Recommended Posts

  • Members

Hey i am seriously looking at the EV ELX passive speakers and was wondering about my amps would they be too much or not enough to run there and be safe. I have a Behringer ep4000 running in stereo @4 ohms each side, and then for subs i have a Behringer epx2000 running my subs Bridged. I was wondering would these be enough to run these speakers or would i need more power. Thanks .

to use the EP4000 to drive the EV ELX loudspeakers. These amps are basically QSC clones if you open them up.

I am planning on using them 2 speakers in each channel. I am planning on getting 4 of them in all.

Its always hard to work out how many watts those things are... I thought the 4000 put out 2000BW (Behringer watts) @ 2ohm. Which, with a bit of guesswork, is appr 1200 BW @ 4 ohm... Converting from Behringer Watts to RMS is somewhere between half and 2/3 which means its putting out 600-800w RMS. If you're talking the ELX 115 - I think it claims RMS at 400w, so that is ok. The 12 inch is 250w so you're on the high side. But probably not too bad.

As for the subs, thats 2000BW bridged @4. With the half to 2/3 rule you're looking at 1000-1200 which is on the high side for 2 subs with an RMS of 400w.

I'm not sure how the passives go, but i cant complain at all about the actives - and the subs are light which you'll love.

so is that 1000 -1200 watts per cabinet and 600 - 800 rms per cabinet?

I won't get into the *B* discussion....
But I will comment on the ELX passive speakers.
I used a pair of the ELX115 cabinets as monitors a few weeks ago powered by a QSC PLX3402 (1-per channel) and I was very impressed with the sound quality and the output of this cab.
Being used as a monitor I ran absolutely ZERO eq on them and had no feedback issues at all.....I have never been able to do that with a passive cabinet while getting useable volume out of them.
They have a very natural flat response, great sounding cab.....and pretty light for how big they are.

I know the active ones get a lot of rave reviews and comes highly recommended on here a lot.

You're talking about 2 tops per side and 2 subs per side right - So you'd get approximately 600-800w per channel on the tops (so 300-400 per box). The subs will see 500-600 per box. On the high side...

I have to agree with aged on this one. a clone is everything looks and sounds like the original, There is a big difference between the two amps mentioned here.

2 per side on the tops only, not the subs, I have two subs on one EPX2000 amp an 2 on another EPX2000 amp. The sub amps are bridged.

We use these for our mains or monitors, depending on the size of venue. As a monitor, they sound so much better than our JBL wedges. I really love the sound quality for such small speakers. Low feedback issues at high volumes really make these ideal for monitors. As for our mains in array, they match pretty much with our QSC's tonality wise, so if we ever need them for an array, they work great and of course, they work and sound great on their own for FOH. Our other speaks are QSC HPR 153i's and HPR 181i's. Next to the 153's these are a perfect match for a small speaker. Eventually will want to go with those exclusively for the monitors and get rid of the JBL wedges. They can get loud, too, but they lack in bass response compared to the EV's. Would like to pick up at least one ELX 115 for a small drum monitor. Love EV stuff and always have, really.
My advice, the week link in your system is the Beheringer gear. The other thing you might want to consider is a 31 band EQ per channel for monitors just in case there is a weird room where the reflections are creating feedback.

I use the powered versions, and for the price, they sound great. The specs you posted were for the 15", but they're pretty close. For smaller size stuff, properly powered, the ELX's will get you by with no problem, and they have the flattest response I've heard out of a "cheaper" loudspeaker...the passive may have some variation, but probably not a lot.

yeah the 15" 's is what i am thinking about getting. if i am not mistaken the passives are 400W continuous to 1600W Peak, so what size amp in watts would i need different from the ones already posted?

Power at about 1.5x the continuous rating and you are pretty good provided you don't do stupid things.
so if i got a speaker continuous rating at 400W then i can put 800w through it? right? I have always been told to keep my rms watts right along that 1.5x or 2x rate.

You can but that was not my suggestion. I would not go beyond 1.5x the RMS rating and that might be too much under some conditions.

The less you know, low less the margin for error.
