First, anyone here use t-nuts instead of regular screws? I was told today that I should buy them because of how heavy my sub is and because it can hold down a sub better...any opinions? Anyone know what size I would need off the top of their head?

Second, if I'm gunna be going through the hassle of taking my big heavy ass box out I was wondering if anyone thinks a top to bottom brace would benefit? I already have one that goes from front to back

As for the t-nuts, that's the way they say it should be done, however if you don't put them in perfectly there's a good chance you'll screw up your box. Also if there not level and lined up perfect with the holes on the sub then the screws won't go in right and your sub won't sit flush. Most of the good box builders will use a thicker or sometimes 2 pieces of wood on the front or wherever the sub sits, if yours does than I wouldn't worry about

Its up to you, but there's risk vs reward, plus you know what they say..."If it ain't broke, don't fix it" (sounds better in a good redneck accent)

As for the brace, it can't hurt, but the front to back one is the important one. If you end up taking the sub out when you put it back in make sure you flatten out the spots where wood came up when you removed the screws. And if your going to use the same holes use 1 size up screws, MDF tends to strip easy, and try to do all the work you gotta do on it at once, the less you unscrew the sub the better, once its got a nice seal you want to try not to break it unless you really have to.

Nice reason for editing BTW

Well what's happening now is the screws are SLOWLY coming out and every week or so I'll be have to go back and tighten them again, and one of the holes lost it's grip or whatever you call it (the screw just keeps spinning and never really tightens down).. But I do understand it would be easy to **** up the tnuts but keep In mind that I only have 1 baffle layer of 3/4mdf

and yea I probably won't mess with the bracing but I fan feel the walls flexing on my box, not anything huge but enough to make me want to ask

Well I went out and bought some 10/24 t nut type things but they screw into the wood not just held inplace by forcing it down... Cuz I figured the BTL could probably pull a t nut out of the wood after a while

More bracing the better

well i knew that i was just wondering if i would even notice a difference

regarding the bracing: maybe maybe not... it would be better for the box overall but i doubt it would make a audible difference

regarding the T nuts. Ive herd the same too man and ive wanted to use them but mine are held in with normal wood screws

brickloaf

ehh im a little weary of it now because the 8 sub holes are awful close to the edge of the baffle and it would be easy to **** it up.

ya if its close i wouldn't do it. but there's a problem if the screws keep coming loose... what screws are u using?

brickloaf

im just guesstimating but id say 1 inch wood screws maybe a tad longer

they dont come super loose, but if i stick a screw driver in there i can tighten it back down after a few weeks of playing

seems like steel threads would just do a better job supporting the sub and hold it down tighter for a better seal

are they course thread or fine thread?

i agree the t nuts sound like a much better mounting system. but the fact u gotta drill out the wood stick the female piece in there then put the bolt thru. I think the main problem is theres no room for error. If the t nut itself isnt lined up with the holes on the sub and the t nuts arent solid in the wood then you will have a worse mounting situation then with normal screws.... i mean look at ur screws now. are they all 100% straight or some of them at an angle?

brickloaf

I don't have acctual t-nuts it's a diff kind but you drill the hole (10/24) in my case, put the "nut" on top and you screw it down into the wood, it's basically a screw that fits another screw inside of it

what I plan on doing is leaving the sub in the box in it's normal position when I drill the holes, that way I can atleast be certain that the nuts will line up, but yea pretty much all my screws are mounted in pretty straight not perfect obviously..

NOpe that isn't it mine has screw like threads that dig into the wood and hold it in

brickloaf

Did it today took me like 2 hours to finish everything, turned out good but had some close calla cause the mdf splits easily

You mean like a drywall anchor?

Nope it's kinda like a hurricane nut but has big teeth like threads that go all the way up...sorry I don't know what there called I asked for t-nuts and the guy showed me these and said they work much better
