Maybe the plate mount should be its own thread?

Quite possibly.



In more related news, these tilters saved the gig last night. I'd been misinformed as to which room I was hired to do at Sheffield City Hall (nice venue, btw, and the first time I've worked there under my own banner). I thought we were going to be in the Ballroom, which is a nice big open rectangular space. Pretty easy to cover that sort of area - my FOH mains would do it fine.

What we were actually in was the Memorial Hall. Looks like this:



The balcony was pretty much sold out, and there was another "wedge" of seating to stage right, pretty much up to the wall. No option to use the flown house speakers, either, though I don't think they're up to much past spoken word.

I set off with centre-clustered subs, 4x 1x15"s across the front of the stage, and then put a 2x10"+HF (think JTR 3TX) up on my crank stands and wound them up to 2.2m off the floor.

Sounded fine towards the back of the ground floor, but you could tell you were right out of the (90x40) HF horn coverage on the balcony. Not good at all, and that was the sold-out bit.

So, I brought the speakers back down, set the tilters for 10 degrees upwards, and cranked them up again. Much much better in the balcony. With a bit of playing around with horizontal angles, I'd got it sounding great for about 90% of the balcony, with the last 10% missing a bit of the very top end. There was about 30 degrees of splay between the cabinets.

Of course, that meant the ground floor was almost entirely out of the main PA's coverage.
On a whim, I'd brought a pair of 6.5" 2-way speakers along, which have fairly wide dispersion in the HF. Got those set up to cover the ground floor, with the low-mids carved out a bit, since the main speakers were putting plenty out anyway.

During the interval, I had people (including musicians) coming down from the balcony and telling me how great the sound was, which was really nice as it felt like I was mixing blind for those guys - I was mixing at the ground floor through the fill speakers, which weren't putting out a complete mix - just vocals and DI'd stuff.

So, yes. Taking these along meant I could get the balcony sounding great. Thanks Dave!

Great Chris! I'm glad they came in handy.

I had to do something similar last year in a hall that was fully round and very reverberant; big dome ceiling.
Quiet Kirtan style music, vocal, bass, harmonium, tabla.
The house system was completely useless; dash arrays pointing nowhere in particular, tons of subs, and eight speakers up behind the balconies pointing towards the center!
I brought in my own stuff and ran 2 SOS down tilted to cover the floor, 2 mains tilted up to catch the side balconies, and 2 delays on tall stand towards the rear of the floor area tilted up  to catch the back balconies. 
With careful aiming and fiddling with delay times, we were able to keep the volume under control which vastly improved the inteligibility.
The placement did a fairly good job of even coverage with minimal overlap.
Lots of comments of the best sound they had heard in that room.

Tilt for success!

From now on, running the rig "Full Tilt Boogie" takes on a completely different meaning.   ;D

Would be interest in a set for the KLA’s as well if you figure this out.

So, Sunday we took a look at the KLA tilting issue, and The Angler isn't a good candidate for this.
The base needs to tilt somewhere around 20 degrees to get the top box horizontal, which is what my friend wants.
I think a purpose-built adapter makes more sense, so I will look into that.

The photo shows the Angler at 12 degrees inserted into the angled setting of the tripod socket.
Interestingly, the pair of KLAs were perfectly balanced over the tripod.

I'm working on a single position bracket to hold a pair of the KLAs.
The top speaker will be at 0 degrees and the bottom at 18 degrees down.
It will use the pin and socket from my regular angler.
I'm calling it the KLAngler.
