I don't think you're nuts. I heard about the same thing from a 604-based speaker at RMAF in 2008 -- honestly, I thought they were just awful. I was both stunned and saddened, as I had been really, REALLY looking forward to hearing them. No idea if the mfg is using their own crossover or GPA's, but for me it eliceted instant listener fatigue each of the 4 or 5 times I went by the room.

Chris Mecurio has posted about what a great job Rick Craig at Selah Audio has done in terms of designing a custom crossover for his pair of GPA 604H-III. Maybe you could contact Rick to see if he'd do one for the II's.
