I have DQ-10s (early model without fuse in back) and DQ-20s. Currently running the DQ-20s with the Apt pre-amp and amp mentioned above. I have two amps as mono-blocks, so 200 Wpc. But sound OK with one amp running both speakers (100 Wpc). I also have a Kinergetics KBA-75 which is fine with both DQs also, but that is 60 pounds of class A all the time
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?
