Enclosure for an inverted mounted sub, does the mounting size change?

[bassranddy]

I'm not sure if my subs excursion will be limited or worse, if my subs surround will take damage if I mount my sub inverted. I don't know if for my 12 I leave the opening at 11 inches or if I flare it or what.. any input would be greatly appreciated!

I always go a little bigger (little meaning ~1/8") and roundover with a 1/4" bit and align and mark the sub mount holes to ensure center placement before the sub is mounted. Hope that helps.

Woah Chris...your still here!!

OP, some people open up the mounting hole a little more for surround clearence. And since a lot of subs have bigger surrounds on todays subs, it's a good idea to do so to prevent damage.
