The specs say, "Two Speed 12V Fan Output (most conditions will not require a fan)". One review says that the fan never turns on. If that's the case, and the fan doesn't normally run, I'll probably put one in the enclosure, just to be on the safe side.
I'm thinking about building it in a 2U rack mount case. I'll use the same phono/XLR connectors that Axiom does for input. Hooking the switch triggered by inserting the phono plug to the single ended/differential jumper. Although I plan on running my first one as mono bridged, I'll include both sets of binding posts, and just parallel them into the single set on the speaker (after setting the PBTL jumpers on the board, of course). But that'll allow me to just lift the lid, reset the jumpers to BTL, and connect up a right channel input and then have a stereo amp.
