Pioneer S-81

摘要

Tallest and slimmest of the speakers here, Pioneer's S-81 is also one of the boldest, both aesthetically and technically. Its curvaceous cabinet looks a million dollars in the supplied black lacquer finish (it is also available in ash veneer) and the narrow front baffle incorporates no fewer than five drive units, although the coaxial 130mm midrange driver and 25mm titanium dome tweeter share the same chassis.rnPioneer has a long history of enabling and advocating high sampling rates and researching the effect of ultrasonic frequencies, and so - uniquely here - the S-81 incorporates a transformerless ribbon supertweeter with a response which is said to reach out to 100kHz.
