I have a question for you guys.
Lets say you need to build a 2 cu ft enclosure for a pair of 12's. These will be powerful mosters and need a really stiff enclosure.
I can make a square box entirely from 3/4" MDF or make the top and sides from fiberglass to get cool shapes. Once the fiberglass is thick enough to be equivalent to the MDF which would weigh less?
