Who remembers the Dahlquist DQ-10's?

I heard them in a friend of my sisters house, who worked at Harmony House in NYC. I cant remember the amp (or receiver) but I remember a Sony Tone Arm that totally blew my mind. he used a glass cake cover to go over his table, or at least, thats what it looked like. he played the most uninteresting piece of classical music I ever heard, and I was glued to and moved b y every single note. If thats not a compliment to those speakers, I don’t know what is. That experience pushed me into the high end, 40 years ago.

It was 'Harmony House II' and they were on the upper west side, definitely on York Ave., can't remember how far up, but pretty sure in the 60's. It was pure high end audio.  It was the first time I saw listening rooms in a hifi store.  It was 1975.  NY in its hi-f hay day.  You walked the streets of Canal street with Scott tuners being displayed on the sidewalk...
