well this is pretty much a fEarful 15sub build with the exception that the skeleton bracing was switched up a bit on the top to accommodate a single handle on the top instead of the 2 sides and I also omitted the terminal plate and mounted the speakon-1/4" combo plugs through the wood itself for less weak areas. I still need to find where to order the grill from, I want one of the bbq grill looking grills cut for it. Next will be a 12/6/1 to accompany it. 3015LF - handles, one for this box and 1 for the 12/6/1 im building next corners, not ideal because they were made for .75" wood but they will do since I bought em. hurricane nuts for mounting the woofer screws for mounting the corners 1/4" - Speakon combo plugs a pair per box Front panel cut out for the woofer test fit hurricane nuts drilled and inserted these so far are way better than t-nuts imho box started putting together as you can see I did dados for better structure, internal dimensions are to specs, i added the depth of the dados to the cuts. also painted the ports black to match my outside some of the bracing and batting installed wasnt too sure how low to go with the batting as to not interfere with tuning so I cut it a little short thought i took more pics but apparently I have nothing of the completed bracing, top, and front being added. this is after 1 coat of duratex. finished minus the grill, thought its still curing hence the color difference on the top left 1 handed carry FTW.
