Well insofar as the reviewers are concerned, the comments on the 3.6s lack of coherency surfaced primarily in the reviews of the 3.7. Since it's introduction in 1999 the 3.6 was heralded by these same reviewers as among the best speakers produced, and certainly among the very best speaker values. With the very best front end equipment the crossover of the 3.6 reveals itself to be a weak link in the speaker design; however, what most people describe as incoherence or discontinuity in the speaker is the inability of their equipment to drive the 3.6 w/sufficient high current wattage. The ribbon will then scream, squeal, and buzz while the other panels will try to avoid bottoming out against the magnets.
