OK:
If it a simple cap (center tweeter) then the higher the MF rating the lower the crossover point (per my basic understanding of such having "capped" a few tweeters to some of my single/wide range drivers).
I simply used "distance" to balance the tweeters SPL's which you most likely could not do.
Also per the SP review the "6" dome tweeters were noted to be active @ 1K HZ, which is exceedingly low - though I assume that the center tweeter activates @ a much higher frequency.
Anyway, unusual design and my only negative feelings about Tekton speakers predominately originate from MC's rants about them.
Never heard them and have ZERO desire to do so (same with the Raven gear).
