Mattl, that looks awesome! Love the modular design. I second Mister Harrison's request: did you make them or buy them? They look great.
Love the JBL L100 Century, I've got their little brothers, the L36 Decade. Jaysoul, the L100 is a real classic. The studio monitor versions 4310, 4311, and 4312 are similarly classic boxes.
(ps. digging your Boogie mix right now)
