TOA RS-21 Studio Reference Monitor Pair

These high-quality TOA cubes, made in Japan in the early 1980s, compare favorably with Auratone and equivalent monitors for your studio.  They were quite expensive when they came out.

Great for hearing how your mix will translate on smaller speakers (100Hz-17kHz).  They are passive, so you'll need a power amp or tuner of some kind to use them.  Corners are a little scuffed up, but drivers and connectors are all in great shape.  Price is for the pair.
