I built these using Fostex FE126 drivers which were eNabled by Plant10 HiFi. For the wood I used 3/4" baltic birch and cut it using the CNC at my dad's wood shop. By cutting rabbits into the side plates and have every cut CNC accurate the glue-up and assembly was trivial.
I hooked these up to my gainclone amp (which I also built) using banana plug speakers wires built from extension cord.
I love them!
