Hi. There was a guy maybe a year or 2 back that sold a bracket you could snap/add to the JBL VRX boxes so that when they were hung 3 or 4 per side, etc, it would get them in more of a straight line. However, I can not find this anymore, nor on a google search. I think he had a buzz name like "straight line" or "straight away".....

Does anyone know if the guy is out there? Sued for using the name "JBL" maybe?

I have hung 3 a side, and it's already getting weird, I think if I go to 4 either the birds above or the earthworms below will be part of the audience ...(lol)

If you need that adapter, you are using the wrong box....  I would argue that you are using the wrong box anyway.  I (as well as many others) really don't like that box.

Preach it, Brother!

Well, and help finding the brackets if still out there appreciated.

If the speakers are good boxes or not, that's another debate. Since we are more of a "come get it" rental house then a sound company,  we buy items to rent that others ask for. In the Michigan market, we were asked over and over for these by hotels, corporate type sound outfits, and did not own them, we had EAW, etc. But the area is full of VRX owners that want to match up, who often want more boxes like theirs to handle a "B" 2nd stage, make delay speakers in a large ballroom, hang in blocks of 2 off truss structures around a boxing ring, whatever.  So if I was picking the best box for a given job, maybe?...maybe not. If someone asks for a Fender Twin Reverb......a vrx box.....a hog light console.....it's a yes or no answer, or they move on with their money until they find who does.

I just want the brackets since I am stuck with them anyhow. Truthfully on any larger outdoor shows we get stuck on I will use the EV stuff first, but I still would not mine having the adapters since we have the truss, cranks, flyware, etc already......why not. But I will say most 932 owners do not power them well. We have the Crown I tech 1200HD (on board BSS processor) and that amp running these are a whole different world then our MA5002VZ or RMX5050's w/drive rack. That matters.

They either got sued or a couple of customers got wise and started asking about engineering approvals and product liability insurance.  Or they found out that using these would void JBL's warranty...

I assume your right. It's hard to tell why, I have been hired and worked directly for/by Harmon Professional a few times, and they seem to have A LOT of money, for things like lawyers, in comparison to other manufacturers. And even if it was a good idea they might STOMP it if it threatens the sales of a higher end product. If the VRX could be tweaked to be better, they might not want that to hurt the other boxes

There is one of the local companies here that has 932 and they also have the small Vertec (the 4887 I think it was) an while this may open a bunch of responses form the VRX haters here, I am only repeating what THEY say (NOT ME) and they actually prefer the 932 to that one .....but hate the rigging.

So again I am not here to praise or attack this box. Or say I like a Ford Mustang more then a Camaro or Challenger.

Well, 4 boxes a side is a 60 curve. So straight out, and then coverage pretty well downwards. I don't think you should have a problem with more then 3 boxes a side, if it's the right tool for the job but if the coverage isn't what you're looking for, better to get the right speaker in there rather then kludge something in that's potentially hazardous. (Tim mentioned liability and engineering approvals; JBL hasn't signed off on this product, so if it fails, YOU will be solely responsible for the aftermath. At least if, say, VerTec rigging fails, and you deployed properly, you can turn to JBl and ask, "What Went Wrong?")

In any case, the VRX is designed to do a specific chore: provide a constant coverage (vertically). If you need to change the angles to alter your coverage pattern, then you need to use a box that is designed to do what you need OR live with what the VRX does. I would never rely on a third party product when it comes to an engineered system.

I have a bunch of the 932LAPs, and I have VerTecs. Each one gets used as appropriate. I won't try to use 4 VRX/side to cover a big 4th of July show, and I won't bring in the VerTecs for a 300pax hotel ballroom gig. They're both useful boxes, just not entirely interchangeable.

By the way, I like how the VRX sounds, and my techs enjoy working with them, and the clients keep hiring it.

Are the rental customers actually asking to hang more than 3?  Someone trying to rent cheaper boxes and make it look like a full blown J hang of something else?

The VRXs were designed with a wider vertical pattern on purpose to be used in smaller situations with less boxes and that's why they have the fixed mount angle.  Straightening them out defeats the design purpose.

The alternative would be something like Meyer Mina's or Melodies.  We have a conference room here at work with a 3 Mina hang and I've worked with Melodies in hotel ballroom/corporate events.  This would be for things where the speakers are supposed to not be a big visual issue and someone has it in their head that a "line array" is called for.

I would think that if someone had an event that needed more SPL than 2-3 VRXs, then they would be going for something else.

I have inventory of both 932s and Vertec 88s.  I'm happy with both boxes, they are money makers in their intended roles.  I don't expect them to perform well outside of their intended roles but thats really beside the point.  When you are hanging loads over peoples heads you are moving into a different aspect of business than simply getting good sound or maximizing the return on inventory investment.  You are dragging a tail of liability and traceability along behind you.  In the event that something goes wrong you NEED traceability.  You NEED to be able to point at the factory drawings and factory instructions for what you used and how you deployed it.  Your liability insurance will fly out the window faster than a falling shackle if they can find a home brew rigging element involved in an "occurrence" as they like to term these things.  You don't want personal injury lawyers in your future. Your insurer will be a buffer against the sharks but your insurance vendor is very grudging about paying out claims, don't give them an out.
