How about this for a bonehead move. Once saw a used pair of DQ10's at Audio Concepts in Houston (out of business just this month, btw, cryin shame) that had a) a factory upgrade capacitor change to the crossover, b) a Panasonic ribbon replacing the top two high frequency drivers, 3) the metal gridwork behind the grill cloth neatly removed from around the drivers, for a price of $250.00 and didn't buy them. Boy, someone had put some TLC into those babies. Wish I had today.
