As
a subcontractor for Washington Professional Systems, ADS was asked to
design and install two sound systems into the National Air Force Museum
at Wright Patterson Air force Base in Dayton Ohio. The systems consisted
of two JBL Vertec PA systems permanently installed above classic
airplanes. The systems are designed to be removed if needed in order to
move aircraft in and out of the museum. The Systems are used by the Air
Force Band for concerts and special events.
