you sure theres enough mounting dpeth for the sub? It looks like its going to hit the port tubes

Wow lol thats what I get for changing my design while I was building it without checking the math

It hits the ports!!

Needs about another quarter inch of clearance.

What should I do? Hopefully I can make this box work or ill just sell it and build another.

add another baffle

How have I never thought of this!? Lol

Make an insert on the outside portion on the baffle good sir

I would add bracing too.

Hmmm seems small is that before or after displacement?

Sub should be as far away from the ports as possible

 

[Jroo 10+ year member]

could you invert the sub?

 

[caseyarndt 10+ year member]

2.18 after displacement according to torres calc

I guess i could invert the sub but I would prefer not to.

Dang I think I can use this box for a type r 12 I have.

do you think 2.18 net is too big for a type-r?

 

[caseyarndt 10+ year member]

I would add bracing too.

Single threaded rod maybe?

I decided to use the cutout of the flush mount baffle to make a mounting ring to bring the sub out another 3/4 inch

and it clears the ports.

It's just the outside edges that are within an inch of the PVC, the center is at least 1.5" away from each port.

do you think cooling will be diminished from the sub being that close?

It will be fine.
