Usher Audio Grand Tower

The Grand Towers are a three-way speaker designed by Joe D'Appolito and built in Taiwan.  With electrostatic-esque speed and resolution combined with the strengths of conventional cone drivers, the Grand Tower is an experience to listen to. Like most top speakers, particular attention was paid to the cabinets along with the use of Usher's proprietary diamond tweeter, in house developed twin 7" mids and dual 11" Eaton Nomex-Kevlar drivers.
