The vents Ive looked at are just 1/2" cold air return covers. Designed to just cut the drywall out and stick in. Their will definitely be some work involved securing it to the wall and not rattling. The speaker cone will be 4" from the vent (the thickness of the wall).So your going to seal this sub to your exterior wall and then just have a vent covering it up?
How deep is the vent?
You also need to make sure it is sealed properly or it will rattle a LOT. Also dont want too big of a depth on your speaker's cone and vent because then your loosely building a 6th order design. Not a big deal but just let it be known is all.
I have not. If it was a regular box arrangement it would already be braced and done. But Im building the box at my dads wood shop rather than my garage. So I had to stop and come back and double check the placement inline with the wall studs.I believe you are in the best box size and tuning range . Have you decided on a bracing pattern ?
Thanks, spent a few days in Keystone snowboarding.What mountains did you go to ? It looks like you have things moving along and in a good direction . I also like the lime green level .
