My first set of "hi-fi" speakers were a pair of these. This was long before the company changed for the worse in the early 1990's. I found the little KG2s bettered later KG models by a good margin. While I've moved along to much pricer gear since then (part of that audiophile disease), my beloved old KGs play daily in a relative's system and I'm still surprised even today how good they sound for their modest price. You could probably run them off a walkman, they're so efficient. With the right tube in circuit, you can gap the midrange dip of this speaker.
