The midrange has its own separate enclosure and the crossover incorporates self resetting protection circuitry for tweeter and midrange protection. The cabinets are in good condition with only a few small imperfections (see photos). 

These speakers were part of the Studio Boy Project S101 that was basically a home studio type rack system that was only sold in Japan and for a hefty price.
