looks like a good start, i would look into bracing the front baffles, could be as simple as a wooden dowel angle cut on the ends to run between the center of the front baffle and the top/bottom of the enclosure where the port braces mount, triangles are hella strong

good idea bro

also, the box will have a 2x4 frame all the way around, which is why its only going to be single mdf

dont really know how to describe it, but try making that brace out of a single piece of mdf, probably will have enough scraps to do it. just make a solid piece to brace it all off and cut out the center, leaving an outside edge

if your talking about the triangle bracing for the baffles... i know what your saying

this sounds like a weak spot there's absolutely no way i wouldn't do double baffles on an enclosure like that i think you might be under estimating how much flex you're going to get

mounting depth looks low.. could be the pics but it looks like the bottom of the magnets would come close..

if single layer, i'd also at least double layer around where the subs go, like a circular 2nd layer where the subs mount. Can't hurt.

Looks good, I would double layer the baffle. Also, maybe its just the angle, but it looks like the magnet will hit when mounting. Maybe move the mounting holes as close to the middle as possible.

yea bro, this box is already almost done, lol... check out my build log

looks quiet

it is:D

just watched the video ... he did change the angle bc it was going to hit and doubled the baffles ...

is your bottom baffle even? the driver side looks lower the the pass side

interesting. Is the design complete? If so, how did you make out? I have to mention though that starting a construction with that kind of compression throat area for 4 18s without figuring for a direct response and tuning resonances, was bold of you. Either way, hope it worked out well! Looks solid!
