Glad you are enjoying your DQ-10s. I loved mine back in the day. Remember, they crave current (amps) more than power (watts). Don't miss the opportunity to try a juicy SS Class A amplifier with them- 100W or more, then you will see what I'm talking about. I did mirror-image, crossover and wiring upgrades to mine, along with more modern driver arrays, and I was very pleased. In a large room with generous spacing from rear and side walls, they image very impressively.
