Having now got the kit from Wayne sitting in my living room I am thinking about what I want to do with the cabinets. I think I would like to use MDF with oak veneer (to match all the dark red mission furniture), but would like to have hardwood rounded corner edges that are say 1/16" proud on the front with a lighter stained front baffle as well as oversize hardwood base and top plates. It seems to me the only easy way to do this would be to double the front baffle, as I wouldn't think any type of spline to attach the corners would be very strong between the hardwood and MDF. Plywood I could see, but not the MDF.

Also, will doubling the front baffle, but leaving the suggested inside dimensions the same, cause any acoustic problems?
