Hello everyone. I auditioned a pair of DQ 8's today thinking of hooking them up to my Sansui 771 receiver. Typical Dalquist, very open. I did notice the low end on one speaker was louder than the other. When I adjusted the balance, of course one was louder, the other was missing low end, mids and highs matched the louder speaker. Grills were not off and I did not request them off thinking there must be a bad driver on one. If that is the case, do both drivers need to be replaced? Anyone with Dalquist experience here? Thanks!!
