JBL PRX600 opinions

Lastly, it seems as though I'm the only with this opinion, nonetheless IMO they both have lousy GBF feedback out of the box.
Out of curiosity, did you have the monitor filters engaged? The only time I've had problems with feedback is when the filters were left out after using them for a rental or sos gig.

Why are we complaining about feedback resistance out of the box? Professionals know how to use eq for this. No one box can be perfect for the hundreds of mics out there...

I've owned 615m's and 612m's and frequently used them over SRX 718's with pleasing results. The 612m is the winner IMO if y Speaking of the HF driver, they tend to rotate themselves loose pretty often. I tried loctite but that ended up cracking the throats of the plastic horns. I'm sure you could come up with a more clever solution, though.

If a tool exists that makes my job easier with no noticeable detractions, why not use it? Someone at jbl took the time to come up with a second preset in the internal DSP that would cut through the wash better and be more stable. I'd be mental not to use it.

Except it doesn't do that at all. It has a low shelf and a high shelf filter intended to compensate for the excessive brightness present in the 'mains' mode, and for half-space loading.

Pretty much universally, 'cutting through on stage' and 'feedback resistant' are opposites. They are both in the same frequency range, one option there is too much, the other there is too little. I prefer whatever works for the artist and the stage.

You know what, I want to say I experimented with that switch but I'm not absolutely sure. I'll go borrow a 612m today and try it, and edit my post if it makes a significant difference.

I assume this reply was intended for me and not Charles, who was quite possibly pointing out my user error.

Nonetheless, I mentioned GBF out of the box because it seems these boxes will be replacing Evans aging SRM450's, which he stated (in his LA post) go out quite often on dry rentals. Most rental customers are not seasoned professionals. They will more than likely be hanging these off of something like a Mackie VLZ at best, without any GEQ's or PEQ's. In this case GBF out of the box is an important point to consider IMO. And even when used by the Silias Pradetto's of the sound industry, why not start out with the cleanest slate possible?

If they don't know enough to have the proper equipment and know how to use it, all bets are off. It's a well-known fact that you cannot idiot-proof anything with the possible exception of death.
 
Re: JBL PRX600 opinions

Thanks for all the insight and info. I went to Guitar Center and played with them this weekend. The wedge angle is the killer for me. Everything else is great about the boxes. I'll probably still pick up a few to replace my aging SRM's, but they won't be taking over wedge duty any time soon.



Thanks!

Re: JBL PRX600 opinions

The JBL is a better box simply because it can make you more money and its lighter, which makes you even more money saving on fuel costs. RCF and other off-brands are really for hobbyists, which is fine if you never intend to do anything interesting with your business. It might sound "better", if you define better as: "I already bought it, so even if it does suck and everyone else in the world hates it, I still must like it because I can't return these off brand speakers and I have to convince myself that I made a good buy" For the record, every speaker that RCF has ever made is wimpy and cheap compared to name brand speakers. I have heard many of them in real life and invariably the reason for purchasing them was, "well, I got a good price on them..."

good luck.

The JBL fanboi in me wants to agree. The logical adult in me is laughing at this.

Unless your dropping several hundred pounds (like close to 1000#), you won't notice it in the MPG. My van loaded averages 15.47 mpg for the last 6 months and the few long trips I have taken without gear in the van I averaged 21-23mpg.

So basically you are trying to say that JBL is a professional box and RCF is not? LOL, here in Europe every average sound guy will probably say the exact opposite thing. Now i will ask you to go and open a similar JBL and RCF boxes and just look inside. The difference is too big to be unnoticed.

I wanted to hold off before suggesting this, but I was at a show last year where Turbosound Milans were deployed as monitors. I was very impressed. The near $1,000 price tag may be an inhibiting factor.

I have a pair of the Turbosound Milan M15s. I have nothing but good things to say about them. They seem like a well thought out box. The monitor angle is good, Monitor angle is on both sides of the cab for mirrored monitors, dual angle pole mount, fly points are built in and it weighs 48lbs. I guess they may seem a little bulkier than other options. I have used them on many bigger shows as front fills or monitors and never had a complaint. Personally I am VERY happy with the sound quality. I will be purchasing at least 2 more.
