Zu Union

State of the union – At Zu, it's final days for Omen II and Soul Supreme as those models phase out and the coaxial Union Bookshelf [$1'799/pr], Union [€2'899/pr] and Union Supreme [$3'899pr] roll in. The first two get a composite-dome tweeter, Supreme the ring radiator of Soul VI. Standard finishes for all are clear hickory and black satin, impedance is 8Ω and sensitivity 99dB.
