Loudspeakers from German manufacturer Canton have impressed Stereophile's review team over the past few years with their combination of careful, solid engineering and excellent sound. CES saw the launch of Canton's revised Reference line. The Reference 3.2 ($15,000/pair), seen here cradled by chief engineer Frank Göbl, features a new tweeter with a ceramic/aluminum /ceramic sandwich dome replacing the earlier version's aluminum/manganese-alloy diaphragm, which pushes up the primary dome breakup mode from around 21kHz to 30kHz. The tweeter dome is recessed within a short waveguide to optimize dispersion in its bottom octaves, and is damped by a small circular plate suspended in front of the center of the dome. The lower frequency drive-units, too, have been extensively revised, while the multilayer enclosure, with its gently curved side panels is acoustically inert, at least as far as the accelerometer measurements Frank showed me were concerned. I was sufficiently impressed to request a pair of Reference 3.2s for review.
