Hello AC. Here is my version of the U-frame to my 12". It is 27.95" tall inclusive the foot, and about 3" wider and deeper than Dannys design to the 8". The sides is 10 degree. In the next weeks I will make test cabinet to some 4" Tang Band full range drivers 4 per side, it`s to get music now. I dont no yet what I will use in the end, to midrange and tweeter, because the speakers will be placed close to the frontwall and the top cabinet have to be sealed.
Perhaps there are space for the A370 in the the sides, but I dont no how far the amp have to be placed from the drivers.
Thanks.



The sides look a little tricky becouce in the first, the sides were not wide enough, so I hade to give it ¾" more MDF.
