I don't know how many times I have had encounters with these. While in college in the 70s I went to a stereo store in Charlotte and heard them for the first time. I had previously lusted after Bose 901s but when I heard Stevie Wonder's Boogie On Reggae Woman on the DQ10s I was amazed at the detail I could hear with instruments and these became my new standard. In about 1980 a guy I worked with had a pair of DQ10s that he was driving with a pair of Sanyo amps, something like 200 watts each, along with a powered subwoofer, thinking how impressive it was at the time. In the mid-80s I went back to graduate school and my roommate had a pair of DQ10s that he drove with a Hafler SS amp and Dynaco tubed preamp. I haven't heard them for about 30 years and wonder how they would hold up today against better designs.
Who remembers the Dahlquist DQ-10's?
My first pair of "high-end" speakers. Power hungry critters but what I would give for an updated pair. I powered these with a Peavey CS-400 and a Maccomack Deluxe Line drive passive preamp!! Those were the days! Young and dumb I suppose?
