Audio Research EC-21 2 way tube crossover [Expired]


no longer for sale

This EC-21 is in good shape. It has no scratches or dents on the faceplate. It has a small scratch on the rack handle. The plate on the back is labeled, crossover frequency 250/500 hz, and bass slope 18/6 db/oct. I believe that these points can be changed with parts from Audio Research. This unit is guaranteed to work but otherwise there is no warranty
