I'm converting a ufw12 cabinet into an 18" Dayton um18. I don't know much about speaker building, especially the cabinet work but I thought this brace might be problematic. Can having the half of the back of the driver fire at a face 5" away (the brace) and he other half firing all the way to the back (16" with the amp installed) cause any kind of non linearities or acoustics problems? I believe the driver will just fit in with the magnet in the cutout. I could widen it up or cut some holes in it if necessary.
