Can a sub box be made of acrylic sheets instead of MDF? Its thinner than MDF and lighter. Is this possible??

The cuts would have to be absolutely perfect and sealed very well to prevent leaks. Any flex in the acrylic will result in a substantial loss of sound volume. While it's possible to make a box completely out of acrylic, I wouldn't recommend it.

leaks?? Wouldn't MDF leak more than acrylic. Wood compare to plastic. A good silicone seal would ensure a waterproof cube (like a fish tank).

I suggest it cause its way cheaper than mdf, and a good cover of dynamat would kill the vibration.

It's brittle and prone to cracking/splitting in a violent environment such as a sub.

I've hand built a few of my aquariums and they were all glass; no acrylics.

MDF is more rigid and more robust, it will stand up to abuse better than acrylics. By the time you get a comparable level of stiffness and durability out of an acrylic sheet, you're basicly looking at bullet-proof "glass"; which is indeed more expensive than MDF.
