I do like a number of systems using full/wide range drivers, particularly when those drivers are actually used in multi-way systems.
My Bache Audio Tribeca speakers use a wide band driver, sans the whizzer, augmented by a super tweeter and 2 woofers. They sound wonderful with my Emotive Audio electronics. Compared to my Audio Physic Tempo Plus speakers, they don't have the razor sharp imaging. Instead it's slightly diffused, which to my ears sounds more natural. My guess is you would hear similar differences between Rethm and Wilson.
