The DA speakers of this period were pretty well received.
I had a set of PS-10's and were great. I sold them to my brother, who had a pair new back in the early 80's. Surrounds rotted and he tossed the unaware new surrounds could be purchased. He's thrilled to have a pair again. Highly recommend any of these. My daughter had a set of PS-6's which were terrific with cloth surround woofers, and they are also now with my brother.
Great deal for 10 bux Celt!
