is it possible to make a speaker box out of bondo without fiberglass.?

Question

i want to add some curves to my square speaker box, but i dont want to spend lots of money on fiberglass. bondo dries pretty hard and is less expensive. if i used somthing like foam for support would it work to cover it in bondo, like 1/2 in thick?

Answer 1

A much easier alternative from standard bondo, which has no support structure to it is the "fiberglass reinforced" bondo that has shredded fiberglass already in it. All parts stores carry this and is only a tad more expensive than the regular. Has much more strength and would be easier to mold than plain unreinforced bondo. You see car customizers often use this to mold areas on cars that they used to mold with lead.

Answer 2

No way! I wouldn't like to be playing opposite you when it breaks my bones - you would probably offer to Bondo my leg or cheek up also : ) Ask around, you can probably buy a used one reasonably. Sometimes schools or teams have lost-property sales at the end of the season, maybe you could borrow one between matches until then?

Answer 3

Once I made speaker boxes out of ply wood for my import truck. They sat on a shelf behind the bench seat; I used different thicknesses of foam rubber and cloth to cover it. the foam did not deaden the sound and made it so when something bumped them nothing got hurt so try foam instead of bondo…….that way you don’t have to sand it!!

Answer 4

yes you can but it would not hold up to alot of base without some kind of mesh or fibers to hold it together

Answer 5

yeah, styrofoam would work, or cardboard, thats what I use on the car.

Wood sounds best though.

Answer 6

as long as you got a form to go by.yes about anything is possible.

Answer 7

Sure!
