Re: Coaxial Wedge Collaboration
The B&C I suggested has an 80deg conical horn. This would be a good balance I think. I find 60deg wedges have the issues you describe for ''mobile'' talent, while overly wide patterns can sometimes spill into other performer's areas which can make life more difficult if you have a lot of separate mixes onstage.
I'd actually suggest not having multiple angles on the build. I'd rather have a design more along the lines of a microwedge-esque sort of thing (though without curves etc), and if you really need a steeper angle, simply prop it slightly with either a basic shim specifically for that purpose, or perhaps even via an integrated fold out locking leg mechanism on the bottom of the wedge.
It would be great if we could come up with something that would be small enough to use as a front fill in a pinch too.
Of course this is just my perspective, others are welcome.
