Just wondering how much space is needed from the sub to the end of the box.
For example, my RE MT has an outer diameter of 15.5", what's the smallest I can go on the height for the box? 16.5"?

Trying to figure this out as my original plan of 18" tall didn't work.

Thanks!

The smallest you can go is the cut-out diameter dimension for the INTERNAL height.

So, for a 15" I usually go with 14.5"

How would that work considering the 15" MT's bolt hole diameter is 14.75"?

I'm not sure I got what you were saying correctly :confused: Maybe I phrased my question incorrectly.

For example, in that image it is labeled as W.

How much farther must the box go on the W axis in that image then the sub cutout?

I've built COUNTLESS boxes for 15" twelve spoke baskets man...

The minimum internal dimension I'd go with is 14.25-14.5" (considering the cut-out dimension is 14.125"). This means the external dimension of the box is 15.75-16" leaving you room for the gasket OD... and to screw the sub in.

:fyi:

Okkkaayyyy I understand now. You was talkin internal :p:.

Thanks a lot for the quick answer nG, you can always be counted on :D

Alright then cool I'll try 16" external.

Have a great day, I'm goin back to my build :) Thanks again!

How about clearance for the pole vent?

Twice the diameter of the vent?

MT doesn't have a Pole Vent. :fyi:
