what kind of stupid scaffolding is that ?!!!! These horizontal pipes are probably cussing what some big cuss words. Yeah that would be a bad scene when they finally give way. there ought to be mandentory inspections of shtuff like that.

Stumbled upon this on Instagram. Fortunately I wasn't at the show to enjoy this in person.

This appears to be 3x QSC KLA12 ratchet strapped to possibly JBL PRX718 subs. I honestly don't think I've ever seen a worse deployment.

It's possible that the two KLA cabinets on the bottom were not being used, except to get the top speaker up higher. Whatever the deployment actually was, it would appear the person who set them up has no concept of the speaker's dispersion.

With a good set of lifts right next to them.  Amazing.

BTW it's not a bad idea if you don't want them to work right.

I became a believer when I finally was able to get an average set of speakers up 14'.   Covered the area very evenly and sounded significantly better (vocal clarity, flat response etc.) than a much better set of speakers stacked.

I wonder what happened to break out the handles on the top 3 boxes...

They don't look like any current RCF models, at least taking a quick look at RCF's site.

In the end, the punters will have a good time and not even care about the poor deployment of these speakers. :(

Yes, it is amazing how much a bit of height can help!

I think we're all in agreement that, other than being a bit odd, a sideways array of 3 or even 4 boxes would work about as fine as can be expected out of a KLA array. It's the rogue box on top that makes this a nightmare.

To add to the devils advocate and agreeing with Keith Broughton, if there was a balcony that needed to get hit by the top kla why wouldn't crossing over at a higher frequency (like 1/2kHz?) so it's more like 18x18* spread. I know the waveguide on the hf should be more like 18x90* even at higher freq, but I seriously doubt the kla don't start beam at higher frequencies.

Even still, I think I would have just done the sideways array and hope [test, measure, listen...] that the 90* splay hits the balcony. Or do what Justin Perrachon suggested with the 2x on sticks with 2x as front fills...
