    What size holes did you cut for the inner/outer circles. I’ll be building an infinite baffle dual opposed manifold and cant find the necessary dimensions anywhere. Thanks!

      Marcus, I measured the subs themselves to figure out the diameter of the “shoulder” where the speaker basket starts to extend back into the enclosure. For some subs, there may be detailed drawings showing exact dimensions, but using a tap measure and getting within 1/8-inch was close enough for me. Also, it’s good to cut test holes in scrap pieces of wood to test the dimensions and cutting process before messing-up your ready-to-install mounting panel.
