DESCRIPTION
Despite its compact size, the UB12Si will faithfully deliver high-output,
high-definition sound for a wide variety of professional applications.
All system elements, including drivers, crossover/filter components,
and the enclosures themselves are designed to meet EAW’s rigorous
standards for reliablility and durability.
The system operates in fully passive mode with an internal passive
crossover/filter network both dividing the signal and providing critical
equalization functions.
Each UB12Si includes a robust 5.25-in woofer mounted in an optimally
vented enclosure and a 1-in soft dome tweeter specifically designed to
provide smooth, studio-quality high-frequency reproduction.
APPLICATION
As a stand alone system, the UB12Si delivers full range output
at surprisingly high levels with flat response for a wide range of
professional audio applications including multimedia production and
presentation, corporate audio/visual systems, retail spaces, project
recording studio, and home theaters. It is also a popular choice as
a secondary distributed reinforcement system providing additional
coverage in virtually any large scale installation such as theaters,
performing arts centers, houses of worship and even arenas and
stadiums.The ultra-compact enclosures can be unobtrusively mounted
almost anywhere. The system includes 1/4-in threaded mounting
points, two sets of which are configured to accept an Omnimount
Series 20.5. They are also magnetically shielded for use in immediate
proximity to video monitors making them an excellent choice for any
multimedia application.
