Amazingly good sounding self powered speaker for their small size and age (1970's design). Very wide near flat bandwidth. Most music will not need a subwoofer with this (goes below 30 Hz), unless you need to feel the full impact of 16 Hz organ pedal tones. Just lacks a bit of clarity. Also the circuitry can be a bit temperamental. One of mine tends to blow its fuse and the auto on doesn't always work. They used the best quality components for their time but today better op amps are available than the TL074 used in these.
