    at work i have access to all types of plexi, what im going to do is build a box with curve to it. what im wondering is, what is the thinnest plexi glass you would with that is serving as a wall to a box holding one MA audio 12?im downfiring the sub so i am going to be able to see the top of it, but i want to make sure the plexi can take the pressure. thanks.


    edit-- plexi is only the top , not the sides or bottom.

    I have used a large piece of 3/8 plexi for two tens with no problems. But that wasn't a high power application.

    I have also used smaller pieces of 3/8 plexi for 3 12's in a ported box with no problems.

    so are you wanting to make a full box out of plexiglass?

    Depends on the thickness. The thin stuff won't take much flex before it cracks. I'd look into using lexan instead.

    no the box with be 3/4" mdf , on bottoms, sides and front and back. its going on the floor between 2 seats, so im going to have a sheet of plexi glass, on the top so you can see down into it. i just need to know if say, 1/4 " plexi will work, or any other sizes, because i have access to them and the thinner they are the more they flex, because its going to bend, not a whole, but lets say if its 2 feet long the starting point will be 8 inches higher than te ending point in a curve, if that makes sense.

    If you need it to bend that much you may be able to use two layers of 1/4". Or use a thicker piece and heat it to bend it to the shape you need. Just don't get it to hot or it will bubble.
