Do not dis the Shure Vocal Master column! These are still state of the art line array speakers used in Las Vegas Casinos right on the strip. Well at least the Sahara Casino, and to be honest it just closed down because it was a dump, but a strip casino is still the big time!
Actually, I saw it up in the catwalk, mounted on a rail and used as a monitor. Also used as a flyrail monitor, an antique JBL Cabaret series 12" floor wedge!
Here is a pic of the Shure from the Sahara. BTW, its still up there and may end up still there when they remodel the place and open under a new name.
