plexi is acrylic. i would guess your question would be acrylic or poly carbonate{lexan}? lexan is expensive but unbreakable.

break resistant--by no means is it unbreakable--i've broken it quite a few times at my job.

Yep. Plexiglass is too prone to shattering, in my experience, while lexan tends to hold up much better. However, I haven't used the obscenely thick versions of plexi, so your mileage with that variety might vary.

1/2" of lexan should do the trick.

I use UL-listed 752 Bullet Resistant Acrylic. Works great in 3/4 or 1" thickness. If you brace strong enough, and seal that acrylic flush or inset on the INTERIOR of the enclosure, you wont barely sense that anything is flexing. like a rock, with i dunno... dual 2000 watters inside? Whatever you want. It'd be a tank.

Your local glass store might have it in stock, but they could always order it for you. I see it pop up on ebay every once in a while for pretty cheap...don't know how reliable it would be though. Lexan in a 3/4" thickness is gonna be pretty expensive...

Here is a source to compare relative prices, you may find it for less somewhere else but this is a start:

http://www.mcmaster.com/

I can't link directly so: go to bottom of the right hand column on the home page, choose plastics under the Raw Material list, on the next page choose sheets, next page choose Acrylic, on next page choose Cast Acrylic and go from there.

Examples: 1" 24x36 sheet of Cast Acrylic $118.00

1" 24x48 sheet of bullet-resistant polycarbonate $495.00
(comparable to Lexan)

well i just finished constructing a box with a plexi window. although i have to finish sanding and painting it. anyways i ordered some 3/8" smoked plexi from ebay i got 3 sheets of 40x48 for $15 plus $32 to ship i cut my hole for the window. then placed the bigest peice of plexi i could fit inside the hole and screwed it in. pre drilled holes a bit larger then the screws though to stop it from cracking. then i put a 2nd peice of plexi one that would fit in the hole on top of the 1st peice. then i used some caulking around the edges and then fiberglassed it around the perimeter. the box is 5.5^3ft and running 2 orion h2 12s with 1800RMS and the plexi has not moved cracked or anything.
