Re: VRX wedges
If you get by the American Bank Center on Friday I can let you hear them for yourself! I'll be down there for the Fiesta de los Ninos event with Manny's rig.
In short though, they rock! they get loud with very little power and sound pretty good doing it. They do require a little eq'ing to tame some 630 boxiness, but other than that they are pretty dang good.
I've only used them in passive mode so I can't comment on the biamp performance. They are very light, small, and low profile, and nice looking. In short, they are everything you might want in a 15'' 2 way wedge.
