We have 10 of the 615m wedges. They are very stable even at absurd levels, but the 45deg angle is a bit annoying to use. I keep a box of various wood blocks with them to make sure that they are pointed in the right direction. At first we thought we were having problems with the HF drivers failing, but it turned out that the compression driver was coming slightly unscrewed from the lens and was rattling. A drop of locktite fixed that problem.
They get very loud, but for a loud drummer a sub is needed. I thought the 612 sounded smoother, but it didn't have the output to deal with bass guitars or synth players.
Also when used with the 618xlf the processing for high pass and alignment is already done in the output from the sub.
We had a pair of the 635 for a demo and they did sound better than the 615m, but we ended up keeping our ISP mains for shows of that size as they get the horns up higher and sounded better to us. Those since have been replaces by 4 jbl vp7335-64dp which are in a completely different league in terms of sound, output and unfortunately price. They aren't pole mount, but sitting on a 2x18 the horns are above everyone's heads. They have more clean output than a tri amped 850z.
