EAW products are continually improved. All specifications are therefore subject to change without notice. UB52/0007840/001/2 pp July 2003 Printed in USA
A 2-way full range system (passive LF/HF crossover) in a com-
pact, vented rectangular enclosure. Includes two 5.25 in
woofers and a 1 in exit compression driver on a 90° x 60°
constant directivity horn. It includes two 1/4"-20 threaded
mounting/suspension points. Six year warranty.
The UB52 is engineered to provide secondary full range cov-
erage from a stage lip or apron mounting location. Also very
effective as an ultra-low profile under balcony fill system. It’s
6.28 in height allows it to be mounted within stage steps and
hidden from view.
Applications include:
Houses of Worship
Performing Arts Centers
Theaters

The 2-way full range loudspeaker system shall incorporate two
5.25 in LF transducers and a 1 in exit compression driver HF
transducer.
The LF drivers shall be mounted in a vented enclosure tuned
for optimum low frequency response. The HF driver shall be
loaded on a constant directivity horn with a nominal coverage
pattern of 90° (h) x 60° (v). An internal passive filter net-
work shall provide fourth order acoustical crossover and sys-
tem equalization.
System frequency response shall vary no more than +/-3 dB
from 98 Hz to 18 kHz measured on axis. The loudspeaker shall
produce a sound pressure level (SPL) of 91 dB SPL on axis at
1 meter with a power input of 1 watt, and shall be capable of
producing a peak output of 119.4 dB SPL on axis at 1 meter.
The loudspeaker shall handle 175 watts of amplifier power
(continuous) and shall have a nominal impedance of 8 ohms.
The loudspeaker enclosure shall be rectangular in shape. It
shall be constructed of exterior grade Baltic birch plywood
and shall employ extensive internal bracing. It shall be fin-
ished in wear-resistant textured black paint. Input connectors
shall be 2-terminal barrier strip. A total of two 1/4"-20
threaded mounting/suspension points (1 each side) shall be
provided. The front of the loudspeaker shall be covered with
a powder coated perforated steel grille.
The two-way full range loudspeaker shall be the EAW model
UB52.
Manufacturing tolerances are +/- 0.13 and +/- 1°
