3.2 vs 896
3.2 excellent mids, sharper tweets, bass that didn’t extend to lowest octaves
896 similar mids, smooth tweeters with amazing details, extended bass with new upgraded titanium drivers.
The Canton 3.2s midrange and bass drivers are aluminum, while the 896.2's are titanium. Here's a comparison of these materials for drivers:
"Titanium does not have the internal damping of aluminum and thus has marginally higher distortion levels...Further, due to its lower stiffness, titanium goes into breakup at a lower frequency. This issue of breakup is worth elaboration. Ideally, a dynamic loudspeaker diaphragm should act as a piston, with all points in uniform motion. However, since diaphragms are not infinitely rigid, there will be a condition at which the forces acting upon it cause oscillating deflections resulting in different points on the surface moving in different directions. Under this condition, the diaphragm is said to be in breakup, and there is an attendant increase in distortion. Both aluminum and titanium compression driver diaphragms are in breakup for much of their response. On a large format driver, the breakup modes for aluminum diaphragms occur as low as 7000 Hz, and for titanium diaphragms, as low as 4000 Hz."
"Much hoopla and marketing hype has been made about the virtues of Titanium as a diaphragm material. It is interesting to note, however, that in lab tests conducted over a decade ago by Dr. Eugene Patronis at the University of Georgia Tech, some surprising results emerged. In an A- B comparison between a Radian 4” diaphragm and 4” Titanium diaphragm in a non-Radian compression driver, there was twice as much 2nd and 3rd order harmonic distortion in the Titanium unit as there was in the Radian diaphragm. In addition, the Radian diaphragm had more extended high frequency response than the Titanium unit."
