Hi Kevin:
That's a nice looking speaker already. Most computer monitors are UGLY. So you're on the right track already.
It's a bit squatty. Might it be possible to orient the main driver and/or the tweeter vertically rather than horizontally? This would give it a bit more height and perhaps look cool.
You're right, the horseshoe shaped feet gotta go. Hmmm, maybe keep the horeshoe shape but make them fatter and turn them around so the ends are in the rear?
You've got a very industrial look going with the 3 vertical tubes that cover the main driver. How about getting rid of them and just doing your mesh screen in a convex shape over the driver?
Charcoal color instead of black?
Just throwing ideas at you, hope it helps.
