After numerous threads and advice from others, I decided on a BASH 500 amp and a TC Sounds 12" Epic that I got from PE. I am using 3/4 MDF. The interior box dimension are 22.25H x 27.25L x 18.25W, with the bracing accounted for, the box volume is roughly 6.3 F3.
Here are a few photos so far.
Very first steps, cutting the MDF. As you can see I did this while I was still constructing my room.
The TC Sounds 12" Epic driver
The front baffle cutouts that I had to pay someone to do for me since I couldn't find anyone who had a plunge router and a jig.
Checking to see if the driver fit well into the cutouts. Seems okay so far.
Current progress. Box nearly assembled.
I intend to use wood filler for all of my gaps and then a 1/4 router to trim all of the edges. Then I will probably just do a brushed on sealer, sanding, and a few brushed on coats of black paint. I haven't really researched what I should be looking for when I buy these materials. But I intend to search trough the posts to see what others have done. It also looks like I am going to use some sort of polyfill for the interior of the box. I need to get some of that too.
Okay, more to come as I complete each step. Thanks for looking.
