I hate to say this, but I totally disagree with ya...while they may not sound optimal in anything but a 1 cubic foot box, you could play it all day long in a 1.2 ft^3 box and the thing wouldn't blow. There's only two ways to blow a sub, exceed the thermal limits on the coil or exceed the excursion capability of the suspension....neither happen because of a simple 10-20% increase in the size of the box.
berglass is difficult to find volume from...if you have the room, try to build a solid, regular shaped (squared off) 3/4" MDF box and use fiberglass to surround the box location for whatever design you are trying to do. fiberglass can be a bitch to leakproof, especially in high SPL installs.
It's difficult to find the EXACT volume of, but it's easy to approximate. To leak proof a 'glass install, take some resin, and mix in some cab-o-sil filler (basically talc) and then add hardener. You now have what is known as a milkshake. Coat the inside of your box, and you will have no leaks what-so-ever.
