my buddy made a 30 liter cabinet for my capacitor assisted 12 inch woofer boombox project. To stiffen the half-inch plywood rear panel put two 2 inch high braces near the driver center and didn't take into account driver depth. My GX1200 and Primus 1200 need another1.5" depth just to meet the baffle and even my GRS 12PT's massive magnet
must be less than 1/8" away from the ribs.
I don't think 12PT's rear vent hole is directly blocked but would fire it exhaust down between those two ribs.
At higher levels (it rates ~6.8mm xmax IIRC) would the "ducted air flow" from the pole piece vent impede cone movement? he brace are needed - I might borrow a multitool and see if I can take out a half inch of height in the magnet area.
Would you worry ? - or just mount the driver and let it sail ?

Not to any degree I'd be concerned about. Plenty of unvented poles out there, and that's worse than what you're proposing. If you were pouring the power on, needed the best cooling possible, or wanted maximum clarity, maybe it would be more worrisome. Given what you've described, I'd let it fly - or at least give it a listen as is with the woofer that fits and make the call after.
