A 2-way full range system (passive LF/HF cr ossover) in a compact, 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 coverage from a stage lip or apron mounting location. Also very
effective as an ultra-low profile un d er balcony fill system. It’s
6.28 in height allows it to be m ounted within stag e steps an d
hidden from view.
Applications include:
Houses of Worship
Performing Arts Centers
Theaters

The 2-way full rang e loudspeak er system shall in corpor ate 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 dir ectivity horn with a n omin al coverag e
pattern of 90° (h) x 60° (v). An internal passive filter network shall provide fourth order acoustical crossover and system equalization.
System frequency response shall vary no more than +/-3 dB
from 98 Hz to 18 kHz measured on axis . The lou dspeaker 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 finished in wear-resistant te xtured black pain t. Input conn ectors
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°
