Alright, I'm looking at three different rigs right now...these are to be an upgraded system from my EV ELX system, which can take just about anything, from bluegrass to jazz/funk to classic rock to metal, and some DJ work in between. This will be used in various combinations for up to 500 people indoors, but mostly under 100 patron band gigs, with the potential for a talent show gig at the high school... Here are the combinations that I'm looking at, right now 4 of each speaker, but may possibly bump up to 6 monitors if budget allows (and budget is a key factor...

JBL PRX625, PRX618S-XLF, & PRX612M = $13,223.99 (13% less)
Advantages: Loudest, cheaper than QSC, lighter...Disadvantages: Less clarity, more expensive than three-way, possible comb filtering issues

JBL PRX635, PRX618S-XLF, & PRX612M = $12,823.99 (18% less)
Advantages: Cheapest, louder than QSC, cleaner than 625's, lighter...Disadvantages: Not as loud, possible comb filtering issues

QSC KW153, KW181, & KW122 = $15,786.99
Advantages: Cleaner sound, easier to pair up, 6 year warranty...Disadvantages: Price, weight

The only reason I'm still contemplating is the talks that originated before about the problems with the Crown amp modules overheating...plus, these will be getting outdoor use in less-than-shady conditions, which could worsen the problems (I have that problem with my EV's right now in direct sunlight...) although it is not a huge deal, it's the general quality control failures that have me worried.

And if you're going to buy that much, look into NSL. You're talking thousands of dollars in savings...

Edit: No QSC at NSL though.

I think what Melvis is saying, is that Presonus is coming out with some new speakers that should really revolutionize small bar audio. Meticulously tuned by David Guinness, of EAW fame, and more recently of Fulcrum audio, and Presonus came together to add processing and communications to loudspeakers allowing direct wireless interface with the Ipad.

The 328Ai caused quite a stir at NAMM. Check the press release area.

Presonus AI has been on my mind but I have a feeling it is going to be on the same level around the ELX series, just my opinion, haven't had a chance to demo yet. And NSL?

NSL = Northern Sound and Light. Great prices on what they carry but you have to be a member to see the discounted price. Membership costs a whopping $1.

Hmm, I'll have to check into that. Plus it's in my home town...sweet!

I think I may end up trying out the PRX635's over 618S-XLF's, with either 6 612M's or 4 612M's and 2 615M's for monitors...I'm just still afraid of the reliability problems from the past, but I'm hoping they will be resolved...Can anyone confirm about the PRX600's behavior in sunlight?

Reliability issues?

The JBL 600 series and other plastic box speakers with DSP onboard ( like the Peavey Impulse 12, Yamaha DSR, QSC K series...)were all pretty much tested and found to be good and VERY similar...The QSC KW series are a step up, but the new speakers from Presonus are going to be a HUGE step up...

Regardless of the Power, or specs, or anything else, having the speakers tuned properly and all the processing power at your fingertips (and your Ipad) will mean more to having awesome sound at your fingertips than just about anything else you can imagine.. I personally am transfixed with anticipation..

I spent hours. days, weeks.. well actually YEARS tuning, re-tuning, second guessing my work, re-evaluating and doing it again and again, and again.. ad infinitum...till I begin to second guess myself...no more.. it's all done for you. This makes the smaart feature of the SL consoles THAT much more useful as the room is the ONLY thing you need to address when you move from venue to venue.. your not going to have to account for the sonic problems that ALMOST every speaker made has until they are processed properly...

Short of spending the kind of money only a BIG concert firm can come up with...

i own a set of kw153 as well as a set of prx635. the qsc's are part of my big system , and whenever i use the prx they go on top of Eon518 subs.

all in all, the eon subs suck, but the prx tops are badass. they're super lightweight and more compact than the qsc. but, hands down, qsc sounds better.

that said - they both take a beating pretty well. i use QSCs as rentals to local DJs and bands, and i know they get abused with clipped signals, poor gain structure, etc. i try to be careful handling them. i use the PRX boxes for bar gigs where i am running sound and can make sure they do not clip, and they get slammed around physically. no problems so far.

if you plan on making a "larger" system one day, get the qsc boxes. they work wonderfully as modular building blocks. but if you like convenience (and , if you are at the StudioLive forums and use a StudioLive mixer then you probably do) then the PRX is a nice alternative.

you'll be happy with either decision i bet !
2xSL16 , KW-series , Macbook pro / ipad , fairly decent mics and DI boxes.

For what its worth, I haven't had any issues with my prx 612s 625s or 618xlfs
They have been used in cold, hot, wet , dusty, and all other environments. I'm not sure where the idea came from that they are plastic boxes. They are birch and stand up to the qsc kws well. The deal breaker for me was the size and weight of the jbls. I don't like to use them without EQ which the Studiolive 32:2:4 handles well. I have used the KWs many times and I think they sound nice as well. The Jbl XLF sub is better than the qsc IMHO. I have mixed 200+ shows on the jbls with no issues. I do think the presonus AIs look good though.

Hmm, on the 3242? Do you have a time machine? haha. I've heard the XLF is better, it seems the JBL speakers retain their "loud but still good" characteristic that I've learned to come of JBL speakers. QSC's seem to be a hair better and flatter sounding. It's a tough choice, but I think budget is starting to take me towards the JBL's...

Haha. Yea 24:4:2
Yea, you hit the nail on the head. These are pa speakers not hifi. They go loud and stay robust up there. I find myself EQ ing differently when pushing them at different keeps. They are not perfect, but for the price weight size they are my 1st pick

Out of curiosity, ever compared the 625's to the 635's?

Also, can anyone else recommend some JBL dealers too?
