Inspired by all those that have done this before me (thanks to Myoung and many others!!!) I decided to build fiberglass and mdf boxes for 2 Infinity 10s. after much debate I decided to make 2 separate boxes instead of 1 big one.
Started with 1 overlapping layer of masking tape followed by 1 overlapping layer of cheap aluminum foil using more tape to seal the seams. Tape protects the carpet 'just in case' the foil ensures that the fiberglass boxes will come out easily.
Next comes the many layers of fiberglass and resin.
