2 cu.ft. optimum / 1.2 cu.ft. min. I figure I am at approx 1.1 with 3/4" box and the volume displaced by the sub itself. I can't understand why an infinite baffle sub "likes" a sealed enclosure

thought that was why someone would buy an "Infinite Baffle" but what do I know?
Second coat of black varnish tonight. Light scuff and a thin spray of clear in the morning then hopefully I will get it in the boat tomorrow eve. Will post pics of the total install when that happens but mostly the box and build-in. The rest is much like the other guys have done already.
