Plato your correct, they are the hybrid of types, there is a electronic filter just like subwoofer amps have on the built in amp for the rear fireing yes, and the super tweet does have a very simple protect Capacitor and whatnot, but the full range are full range No filters, your amps are litterally connected direct to the voice coil of the drivers Actully soldered right in, natural and transparent, dynamic and all that, but I was not saying they are the best(well they are from what I hear) but just to prove you definatly have to be open minded and try as many variations as possible, Cliché type audiophile speakers are not necessarily my cup of tea in the end I guess. I like pure simplicity and practicality, Drive deep bass with seperate amps which these do, and Intergrate perfectly, they do not sound like conventional subs do with satelite speakers, and run nothing smaller than 10" drivers throuout, which I strongly believe in as well, okay not the tweeter but you guys get the point. Simple high quality Big sound, covering frequency extremes most speakers cannot touch and they handle the bass without draining your main amps, its really a design that I believe handles key problems many manufactures do not look at, and just add complex crossovers to fix the problem.
