Thanks fuzz. I have looked far and wide and have considered everything you thoughtfully mentioned above. I even took my burl into Woodcraft and held it up against everything they had and that's why I got the wenge as it provided the contrast I was looking for in the store, but now that I have it at home and cut into strips and placed it into the cutouts, I'm not too fond of it. I would really like to use ebony, but I can't find a piece that I can cut down at a reasonable price, plus it is harder and tougher to work with than the wenge and my table saw didn't like that stuff too much.
I plan on dyeing these with either the bright red, bordeaux, or the red mahogany Transtint dyes I bought if I like the way they look after testing. I got the inspiration from the bright red pelin burl on a set of Cirrus Blacks from Vapor Sound:
I'm gonna wait until I have the rest of the speaker finished before I decide on the trim as the dye and Waterlox will change the way they look. If mine turn out even remotely close to the beauties above I'll be elated.
