I am in the process of putting together my 281 and 81 kits. When we pre-drilled the holes for the speakers, we placed them all at 12, 3, 6, and 9 o'clock. As a result, the T-nut's overhang in locations where the t-nut is adjacent to an adjoining 3/4" mdf. This causes a gap about 1/16th " that runs almost the entire length of the edge. There are 3 possible solutions that I see, and would appreciate recommendations: 1. Remove the t-nuts that are an issue, and simply go without a few screws on each speaker. 2. Take a tool and cut out a small piece of mdf so that the t-nut is not an issue and the edges line up flush. Also, the t-nut does not protrude so far out that I would have to cut thru the entire 3/4", looks to be about 1/4th to 3/8" 3. Fill the gap in with a filler. Thanks for your suggestions.
