Down firing subwoofers
#21
I will be definitely adding some additional bracing but for the sake of airspace, I was considering either fiberglassing the inside of the sub portion of box or cutting some steel rings and through bolting. Although I have stood and bounced all over the front of that box and it is damn sturdy. I really need to get the runners installed so I can accurately gauge my space underneath the box. It's been a busy week.

i don't think the box isn't sturdy and said the opposite, i was more referring the the small amount of mdf left after routing that the subs are mounted to/supported by. that seemed pretty thin. as far as bracing the enclosure itself, for boxes the size of yours i have used left over 2x4 scraps and cut them down to size, then glue and screw between the face and back. cheap, simple, effective.

I gotcha. Thanks for the suggestion. What do you recommend I do to not affect airspace. I am at a little over 1.5 cu ft which is the minimum airspace for 3 MK V's. If I add anything internally, I will drop below that number which I cant have. That's the only reason I suggested fiberglass.
-edit-
you have some router skills. you could always make up something along the lines of this (the middle piece), but given the size of your enclosure i think it would be a waste of time and effort
-second edit-
looking at your box you would only need 4 braces - one between each sub and one on each end - and i think you would be golden. that brings it down to 0.049cf, so you would net 1.451cf.

Replying back to this thread, I never actually got anything done..yet lol. I had blue prints made up by Car audio Fabrication, but no audio shop here has replied to me sending in the request, and haven't heard too many good positive things about shops here. I would build it myself, but do not have the tools or experience to do it lol.

ask around your friends and family and see if anyone works in construction. it is really pretty simple to build an enclosure but can be daunting ig you have never done it before. if all else fails you could always find a carpenter on CL to have it built, and most likely they won't charge you anywhere near what an audio shop would. they are notoriously overpriced.
