Sensitive Essence
Zu Audio goes its own way when it comes to speaker design goals, emphasizing sensitivity and dynamic range. The Utah company's new Essence ($5000/pair) covers almost the entire audioband with a single 10" drive-unit, augmenting this unit's output from the central "whizzer cone" in the top octave with a ribbon supertweeter. Sensitivity is claimed to be in the high 90s! The enclosure is constructed from Baltic birch ply with an outer MDF cladding, and the internal wiring is, of course, Zu's own cable, with cold-forged, solder-less connections to the Cardas binding posts.
