I will soon be building a box for a DC Level 5 18 M1. I've done a little research but I haven't found much on the M1.
I'm going to brace it of course, and double baffle the front. Maybe I'll put a few coats of resin on the inside. Will resin make a noticeable difference? What would be a good box volume? I want it tuned to ~30hz. I have a suv...
Any help is greatly appreciated!
