The Gryphon woofer towers have no cross-over frequency adjustment.
one wonders about whether perfect bass tower integration with your Gryphon's might have changed your Clarisys path? might it have 'filled in' any high frequency issues in your room? i know how it worked for me, when i attained bass integration 'singularity' everything gelled.
there were many posts 3-4 years ago addressing proper bass tower integration thinking and approaches to crossovers, preamps, and such things. foretelling of this situation.
mostly great music reproduction performance comes down to bass integration and frequency balance. you got it, or you don't got it. sure there are different driver types and matters of taste, but musical rightness needs balance. or the magic is missing. and we keep searching.
and when lower octaves are concerned, sins of omission are preferred. but the better the deep bass, the more complete and natural are the highs.
