I've been searching for some subs for a long time and finally decided on 4 jbl srx718 because so many people said they're an excellent subwoofer. Anyway, i've got £2,600 to buy a pair of tops but was wondering, after seeing these mighty 2 speakers, which would have the best sound quality and which, if any, has the highest spl output? I'm from manchester in england and in this god damn country, you can't seem to hear a pair on demo anywhere because most shops have closed down and are now just internet only retailers so I thought i'd ask you guys. I guess if I go for a pair of the srx722 ones i'll power them with a Crown ma3600 and if I go for the ev qrx212 i'll power them with a qsc plx3602.

I use a dbx driverack 260 for processing and the style that we, me and my girlfriend play is pumping techno music with lots of lovely low basslines that try and dislodge my kidneys. I power the 4 srx718 subs off a crown ma5002 that I got cheap. I have to say, we tried the subs out at a party at my friends house last weekend and the bass was mental. I used his jbl mrx525 on top of them but I want dual 12" myself because I personally think that 12" drivers give out better midrange clarity.
 
They are both excellent speakers and you can't go wrong with either one. My question is, why use a different amp on them? The Crown or the QSC will work well with either of these speakers.
 
Because the ev qrx212 is rated at 600 watts rms and the jbl srx722 is rated at 1,200 watts rms. Using a qsc plx3601 on an srx722 would be underpowering it by 100 watts and using a crown ma3600 on an ev srx722 would be severly overpowering it by 1,000 watts.
 
The EV is rated at 600/1200/2400 watts with a sensitivity of 102db.
The JBL is rated at 1200/2400/4800 watts with a sensitivity of 97db.

The QSC is rated at 1250 watts stereo into a 4 ohm load at 1khz.
The CROWN is rated at 1565 watts stereo into a 4 ohm load at 1khz.

The QSC is rated at 725 watts stereo into an 8 ohm load at 20-20hz (FTC)
The CROWN is rated at 885 watts stereo into an 8 ohm load at 20-20hz (FTC)

I don’t see a big difference in power ratings between these amplifiers but there is a big difference between the speakers. The JBL needs almost twice the power to play as loud as the EV even though it has twice the power handling.

I think a pair of the EVs would work well with either of these amps in stereo mode.
I think it would also work with the JBLs. If you are using a crossover between the subs and satellites the amp will not have to reproduce low frequencies.

Like I said, I don’t think you can go wrong either way.
 
I dont pay attention to the 1kh wattage ratings, the full bandwidth specs give you a more accurate idea of what kind of power you might get out of it. At full bandwidth the qsc is rated as giving out 1,100 watts per channel and the ma3600 only gives a 1khz rating. The crown may not give out much more than the qsc per channel stereo into 4 ohms but I feel its definately too much power for the ev qrx212.
 
I'd get the EV's myself.
But the 722's are some mighty fine speakers on there own also.

If i was you, I'd bi-amp them to get the most out of them. They will sound better, and you will have better control of your sound.

The 260 will have all the presets you need to do it.
The big H/F drivers will easily take a amp such as a QSC RMX 850 (Thats what i use on mine) And @ 8ohms, The amp is just idiling..

Look for something around 200-300 watts a channel..Seems like total overkill, but it works well. I've had mine on Highs for 4+ years.

I'd use the macro 3600 on Mids..macro's are GREAT sounding amps.
You could use a Crown XLS 202 on highs, Macro 3600 on mids and the 5002
on subs and have one hell of a rig!
Plus with the good feature set of the Driverack 260, You could keep it limited to prevent failure...
 
As much as i'd like to buy a ma5002 and a xls202 i'm not sure I can afford it, i'm just about out of money, apart from having about £3,200 left which includes the £2,600 to buy a pair of either the jbl's or ev's. The ma5002 amps alone are bteween £1,100-£1,400 used. If i get the ev's i'll have £700 left for a single amp to run them, I really cant afford to biamp then. What exactly would biamping them do for me anyway? Make the sound quality better due to bypassing the internal passive crossover? Make them a tad louder?
 
A few weeks ago my friends band played and tried out a new sound man.

He had the QRX212 on top of QRX 218S.


It was sexy! Sounded fantastic and banged that 60hz kick drum ito peoples skulls. I didnt get a good look but he was running EV amps too I don't know what model.
 
I like EV amps. I heard 2 Q1212 powering 2 Tour X 152 tops and a pair of Tour X 2181 subs last year at a demo near me and I was impressed with them. I have to say about the Tour X 2181 subs though that they were very nice but sounded a tad boomy. Maybe due to the huge port and high cabinet tuning frequency than the 4 SRX718 subs that I have.
 
I aggree with you. But I was impressed with the TX2181 for the price they sell for, £1,099 each. I think they're more aimed, or judging by their frequency range low limits, the depth they go down to, are probably aimed at the dance and rock markets.
 
I'm a JBL fan, however if i didn't have the JBL's I do I'd take a hard look at EV. In my garage I have an ancient pair of EV 3 ways with 15' woofers, 8 inch mid cone and the same compression driver HF that Klipsch used in the klipschorn. The model # is PI-15-3 I've had them forever, and they just go and go! This says a lot for EV build quality.

Best,

Paul
 
I Run All Tour X Speakers, our company owns the entire line, We Do A lot of karaoke, Club DJ, as well as live sound and run Tour X for everything, One of our Smaller Rigs is the setup that Mathew mentioned, We run a pair of the single 15 tour x tops, Above a pair of the single 18 Tour X subs, and Run this with an EV Q1212, the Subs have a built in Crossover so no need for separate processing, which i was skeptical of at first but sounds absolutely amazing, although when we run the dual 18's on our larger rig we use the EV DC one. We are an EV company through and through, Started with JBL, but have long since abandoned them. I've gotten more Compliments off of our Tour X line then anything we've ever run. Not to mention on top of the amazing sound they are very easy on the eyes :)
 
The High Pass filter is Built into the subs, It's really nice if you want to Do a gig without bringing out a separate crossover, You just run your full signal into the subs and they take care of the rest. And it only takes one Amplifier because the subs also pass your power. For Small events i run that Rig, powered by the EV 1212, and then For my Medium sized events i run the same rig Powered by the Crown XTI6000. I love it!
 
The only recommended high pass filter I see with the sub is for 30hz to filter out subsonic frequencies. I don't see a high pass filter for a satellite.
 
It's there I promise, how i've been runnin them for the last 7 months, and they sound amazing. I was EXTREMELY skeptical about how well that would work before i got them and just planned on using a digital crossover which is what i usually run, but once we got them in and realized we could run the system like that and for 50 percent of our gigs only have to have one big amp in the rack, we were sold , and it really sounds great.
 
Minor correction here...it is the TX1181 that has the filter in it...but it is a low pass filter for the sub...the parallel connection passes full range audio to the tops. This way you get some added coupling of the low frequencies and can use the tops as stand alone boxes...

Bottom line is you can achieve very good results without a crossover on this system, however, you would unleash the system even more and have more control when used with a processor such as our DC-One...

I'd like a pair of the EV TX1152 mid/high speakers but I boubt they'd keep up in spl with the SRX728 subs I have. I liked the EV Tour X speakers I heard at a shop though, definately. They have a duller sound compared to the JBL MRX515 I heard, which makes me think that they may have a flatter frequency response. I reckon i'm gonna go for a pair of EV QRX212 to go on top of my 728 subs, although i've seen a totally mint pair of older JBL SR4726A speakers for £300 the pair so if I can find another pair I might go for them since they're excellent speakers. I'l have to see if I can find another pair of the SR4726A and if I can't i'll go for the pair of EV QRX212.
