skittlesRgood Posted September 19, 2009 Report Share Posted September 19, 2009 it seems to me that a lot of people overbuild enclosures. i dont understand when people put tons of fiberglas on the edges of the box and put 50 screws through a double baffle. i used to think you needed a ton of screws to hold a box together untill i tried to take a box apart. it took some really hard wacks from a hammer to break the joints. the wood broke apart before the glue gave out. now of corse i still use screws but i use MUCH less than i used to. the only screws through my second baffle are the ones holding the subs in place. we add double baffles and lots of bracing to stop flexing. so with all the bracing, and the glue holding stronger than the wood, the box would have to flex so much that the wood, across the entire baffle, breaks/splits. im not trying to bash anyone thats done these things. its always better to overbuild than underbuild, but my question is: has anyone ever had a box fail because they didnt put more screws in, or fiberglass every edge?

I've never had one fail, but the reason people feel tempted to do that IMO is to stop each panel from individually, more efficiency = moar DeeBeez Quote Link to comment Share on other sites More sharing options...

BLuejoules Posted September 19, 2009 Report Share Posted September 19, 2009 I think he's talking about the fiberglassing. Quote IG: devinthydude Link to comment Share on other sites More sharing options...
justin smith Posted September 19, 2009 Report Share Posted September 19, 2009 ive never had a box blowout except 1 prefab and i was running 2 or 3k through it. i always think that i under build them compared to everyone else on here, but everyone of my friends think that they are stupidly over built untill i show them boxes on here. i just use the old glue and a couple screws(like 4 down each seam) no glassing yet and for my only box with a double baffle put the first baffle on the box then i just used like a whole tube of liquid nails and just stood on it for a few mintue till it tacked up then just let dry the rest of the way, it work just as good as all these super boxes though i think, you could set something on all the panels and you could tap the box on all sides and it wouldnt bounce. i think all the internal bracing messes up the air flow in the box i would rather just use double or triple thick walls imho Quote justin smith 1996 mercury grand marquis 20'' bentchi b7 lexani n3000 245/35/20 cactus 5kw at 1ohm dcr(beast) 2 18'' btl's in a 14.15^ft wall tuned to 35hz with 210'' of port kicker zx650.4 componets in still the works 200amp motorcraft alt xs power d3100 (beast) kenwood ddx512 h.u. you mean my EX? the one I dumped? just remember every time you kiss her that i used to cum in her mouth and BTW your girl just called me.... pure pwnage Link to comment Share on other sites More sharing options...
wL<3bass Posted September 19, 2009 Report Share Posted September 19, 2009 I use to be one of those people who would use tons of screws, I stopped doing that after my 2nd box....I use a brad nailer and basically use the brad nails to pull the wood tight for strong glue joints.....

Noob_On_Droid Posted September 19, 2009 Report Share Posted September 19, 2009 i think noob meant w/o fiberglass the box could leak air and there goes some db's I meant, glass and bracing are overdone to prevent the open panels from converting the acoustic energy out of the box instead of out the port. To many screws are just silly. Quote Link to comment Share on other sites More sharing options...

To many screws are just silly. the joints arnt going to seperate. just make sure you have a good bead of glue on and you should be good. the only "overbuilding" i do is adding caulking to the edges after i get the box together. a box is strongest in the edges because it has support from a bend. the only way i see glass helping is by putting it in the middle of the board, or across the entire thing of corse. thats where it will actualy flex. i just think people are waisting time and money with some of these extras.

I throw a layer of 2 ounce glass on kerfs when i make them.
