fiberglassing inside of boxes

does fiberglassing the entire inside of enclosures help with getting rid of box flex without extra bracing? a smaller box for a single 12 about 2.5 cubes or so. any experiences?

i did it for my box 8 cubes for a 18. slot port and fg the inside. no other bracing for now...

I glassed the box on the inside for my RE XXX 15d2. It helped me get a little better airflow and i have a lot of bracing so I dunno if the flex was a problem before. But it does help seal the box. and it did make a little difference in the sq

yes it will help. same concept as adding a 5th layer to a fiberglass box that already has 4 layers.

Dont rely on it for significant bracing. Do it right and the less costly way. For example, a 2x4 is much cheaper.

not going to fix a dramatic amount of box flex.

Brace it and glass it. All-thread is cheap too

thanks for all the input. i did consider doing a brace. how about a double baffle? ive never double baffled the front of a box. is it worth it or does it make more sense to just do some cross bracing?

im debating on how im gonna brace my box.

I've read a hundred times, nothing beats member bracing. Double baffle would help too.

ive read it alot too i just wanted another opinion. ill prob go with both the bracing and fiberglass that bish

mdf is not solid, air will pass thru it, bracing and a coat of resin is the best way to go.

A... air will pass through it cause its not solid?? WTF you talkin about??

B. Resin will not add any kind of bracing to the box.. might act as a filler like caulk or glue or bondo

C. MDF is not solid?? wtf you talkin about

D. FIBERGLASSING the entire inside might help a little bit... but thats dam expensive for the POSSIBLE result.

E. Fiberglass gains its strength with curves and turns... you've never seen a whole SQAURE or RECTANGLE box made outta fiberglass... Most boxes with fiberglass have the base of the box made with MDF, and then just the top (which is usually curved or rounded somewhat for the cosmetic appeal) is made with fiberglass

F... so, did you fiberglass the whole inside, or just cover it in resin

G.. MDF is not solid and air will pass through it... WTF??

no glass just the resin? the glass shouldnt hurt and only add structural integrety id think
