Acrylic for a sub enclosure?

I have been toying with the idea of useing acrylic for a sub box but was wondering what you guy's think about something like that, or if anyone has done it. I think it would look very cool but I am not sure of the reasons I haven't seen them. Any opinions????

No, I don't think you can get plexi thick enough. I think you can get acrylic thick enough but I don't know at what price. I will do some searching to see if it is cost prohibitive to use it.

3/4 inch should be thick enough for a sub, but at $20 a square foot it adds up.

We're all in this together!

Re: Acrylic for a sub enclosure?

Price is an issue for sure. Have any of you ever seen a build like this?

Re: Acrylic for a sub enclosure?

I used plexiglass on boxes but never build the whole thing out of plexi, I've seen boxes build out of plexi, to much work plus the sheet of 3/4 plexi its about $1000 if you buy it from a glass company but if can get it from a distributor its about $500, still you need a nice table saw..I'm talking $2000 table saw to be able to cut the plexi o any acrylic that tick!

The best thing is to build the box with wood and add couple pieces of plexi, but you have to finish the inside of the box to make it look good!

Re: Acrylic for a sub enclosure?

Those ones that Mike linked to looked great. Rodny, why a $2000 saw. Is it because of the speed and you can't get one that will do the job for less? I thought a good saw with maybe a different type of blade would work.

Re: Acrylic for a sub enclosure?

1" or 3/4 plexi is hard to cut with a cheap table saw, thats why I said a $2000 it doesn't have to be that much but a really good table saw and a good blade.

A lot of those boxes that you see build out of plexi are cut with water jet or laser cut, when using a blade the cut is pretty rough that = a lot of sanding and polishing, every screw hole has to be pre-drill with a special drill bit or you can use a plexi-glue.

You still need to do braces because even the 3/4 plexi will flex!

just a lot of work


The best thing is to let a shop cut the plexi with a laser this way you don't have to sand and it will be minimum polishing.
