Default Sub Mounting Help....

So I'm playing some DJ Slow 'N Throw as I just found out about this music and all is well till one note I hear this loud whistling and rattling noise. I turned down the music and when i get home for lunch I inspect the damage lol...seems one of my 18's ripped the head right off of 3 of the wood screw used to mount the sub and one side was lifting up when it would hit causing the whistle while it was close to the wood and the rattling when it would hit low notes.

I've used T-Nuts and bolts before but don't really like them as the phillips head seems to just deteriorate after a few ins and outs and apparently the wood screws are no match for the 18's either. Any thoughts on how else to mount these bad boys?

I'd love to use T-Nuts and hex head bolts but have been unable to find any long enough to get through the double baffle....

Thoughts?!?

Must be some weak screws. I had my 40lb subs mounted upside down and never broke a screw head.

The only other solution is "T"nuts or hurricane nuts. And use allen head bolts instead of phillips.

Mcmaster carr can get you any length. Great website. Its what I used. Also drill your holes for subs, then put some glue on the t nuts to help hold them in while putting sub in.

Ive never had a problem with coarse thread drywall screws.

I wont use tnuts, they're nice until the insert comes loose on the inside and then you cant get it out

SELF TAPPING SCREWS USED FOR SHEET METAL! i used em on my last box and they seemed to work great! you can buy them in big bags/boxes, they have a nice hex head on them to get a solid torque on them yet they are much thicker than drywall screws and have a pretty good thread depth on them still. I'll continue to use these

when i bought my 9518 someone had drilled the screw holes for use with lag bolts and i didn't want to use lag bolts so i used some long star head screws with small washers. maybe you could use them as i have had no issues with them and i beat the sub hard.

I prefer the torx (star) head screws or square head screws

I think that's the route I'm gonna go! The torx route anyway...I do need to find some washers small enough that they won't rub the surround though. I assessed the damage today and there were 2 screws that were in pieces and it was causing the sub to jump up out of the box. I also found while testing after temporarily mounting it that I need moar bracing lol...my double baffle top flexes like a 1/4" with 2x4 bracing...think it's time to check out the all thread! Thanks for the input everyone
