I built myself my first cab, 1x 12 with a fully enclosed back. Now I've finished i think it sounds better with a partially open back.

Has anyone ever used one or two of those tubular ports that speakers sometimes have? Or anything else for that matter or do i need to make a new 3/4 back?

Takethe back panel off and cut 1/3 of it off.
