Acrylic Horn?
Could you build a horn loaded subwoofer like the T60 out of acrylic? I've just had thoughts of lighting up one with led's and showing off the awesome design by making it see through. Possible issues are air tightness and throat pressure, the question is could it handle it and could it be built? I'll leave cost analysis to another day. Also, what kind of thickness would be strong enough? Assume that if a width less than 1/2 inch is used all the respective panel sizes are adjusted automatically.

1/2 inch, which goes for $300 per 4x8 sheet.Also, what kind of thickness would be strong enough?
Better wait until transparent aluminum becomes available.

Re: Acrylic Horn?
It would be rough if you messed up a panel at that kind of price, but I'm sure there is someone who could afford it (hopefully me in 10 years). I too would like to see a 3D printed cab!

Even if one side was done with Acrylic, it would look cool.

go with lexan.
I've personally been thinking about doing ply cabs, but cnc routing out reliefs, and replacing with foam/fiberglass to bring weight down.

300, 800, just numbers when you get that high. lol. Might as well mold it out of polyester resin.
you could also probably get by with thinner lexan for an autotuba. lol.

I like how you think, may as well go all the way if you're going to spend that kind of money.
