We sold them 20 yeaqrs ago, it seems ! I bet the stuff is old stock at M123. The bass bin worked very well, but the sattelites awere made of plastic and use piezo horns facing UPWARDS .... not a very efficient way to project the sound. It was a good alternative to the bulk of it's day, but there are so many better choices today. The woofer is passive and has a psuedo-crossover built in, so it will work with any pair of 8 ohm tops, maybe someone can utilize the bottom with a nice set of small EV's or something.
