Ok, My first advice would be to take Elgordo up on his offer, you can't beat free advice from someone who knows this old speaker very well. I used to own a pair years ago, If I recall..these speakers are not setup for bi-amp in stock form. I would recone both woofers and make or buy a good set of stands, the stock stands are not very good but would be easy to copy in a much more sturdy look a like. The DQ-10's have a left and a right speaker and need to be setup as such. These speakers image very well and were a true early highend design that should sound very good even by todays standards. I see them here on audiogon from time to time for around $500 if I recall.
