Joe X Posted May 6, 2013 Report Share Posted May 6, 2013 I've never seen or heard of anyone using all thread before on sub boxes. Do you use large washers and bolts on the in and out to hold them rigidly together? I'd rather not have bolts sticking out the sides and top and bottom box if possible. Just double up all around and brace around the center of the panels with thicker wooden dowel rods both screwed and glued if you don't want to use threaded metallic, that's enough to keep larger enclosures than what you are planning on steady. And sound quality does not depend solely on box stiffness, it depends in so much more. Link to comment Share on other sites More sharing options...
ncc74656 Posted May 6, 2013 Author Report Share Posted May 6, 2013 with doubling do I just glue panels together or do I use screws as well? I'll use some 2" hard wood dowells inside the box, that should work right? as far as box construction goes, what else should I know to get the most from this guy? nothing, gutted Link to comment Share on other sites More sharing options...
Socky Posted May 6, 2013 Report Share Posted May 6, 2013 i believe their is a guy on here name joe x, he will do a box design for free, ask him about how it would look with just thread rod. have it roughly 7-8 cubes so its semi efficient, having a larger enclosure helps the use of less power, and result of reaching louder scores, but it takes alot of testing and tuning.

ncc74656 Posted May 6, 2013 Author Report Share Posted May 6, 2013 will the SP4 need rear bracing as far as the magnet goes or can it just hang there? i have read that you want to support the magnets on subs like this but then others have said the Fi has a very strong basket? nothing, gutted Link to comment Share on other sites More sharing options...
DylanBunch Posted May 7, 2013 Report Share Posted May 7, 2013 If the sub is facing up no, but if its facing front or back I dont think its a bad idea.. 2006 Ford Explorer 2 Team AA/Sundown 15s 6th order Ct Sounds 7k 4 PRV Mr500 8s Rockford p1000-2 Team Subsonic Lows Link to comment Share on other sites More sharing options...
ncc74656 Posted May 7, 2013 Author Report Share Posted May 7, 2013 it will be facing forward so it will be supported by the front screws only. nothing, gutted Link to comment Share on other sites More sharing options...
Emmet Posted May 7, 2013 Report Share Posted May 7, 2013 it will be facing forward so it will be supported by the front screws only. You'd want to use something a bit heavier than screws for a sub like an sp4. Like T nuts or socket cap machine screws and threaded inserts. i shook this one kids hand and it just folded in mine. long story short i fucked his girlfriendso.. yeah..

bkolfo4 Posted May 7, 2013 Report Share Posted May 7, 2013 I use #12 sheet metal screws from Lowe's. Pan head, non-self drilling. Predrill with 1/8" hole. Never had an issue. Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.
