Danny,
I'm seriously considering building a pair of these with two 12" drivers. The height would work since there would be 1/8" between the edge of the driver and the top/bottom of the sides with both 8" and 12" drivers.
However, it doesn't look to me like the same side depth will work with the 12" drivers. For the 8" drivers the sides are 12.5" deep. However, the mounting flange for the 12" driver is around 12.625".
With the 8" drivers there is 1.875" between the edges of the mounting flange and the edges of the sides (8.75" mounting diameter on 12.5" deep sides). To keep this same 1.875" spacing between the edges of the 12" drivers and the edges of the sides, the sides would need to be 16.375" deep. Would this be correct and would it work?
As for the width of the front, would moving the center of the 12" drivers farther back (centered on a 16.375" deep side vs centered on a 12.5" deep side) offset the difference in mounting depth (5" for the 8" drivers vs 6 3/8" for the 12" drivers) or would the front need to be wider?
Mike
