UB12Se-888110(C)/2 pp 5/1/00
Printed in USA
The two-way full range loudspeaker system shall incorporate
a 5.25-in LF transducers and a 1-in soft dome tweeter HF
transducer. The system shall be available in mirror-imaged
left and right channel versions.
The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The drivers shall be
magnetically shielded for use in immediate proximity to
video monitors. 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 20 kHz measured on axis. Operated with a high
pass filter set a 90 Hz (24 dB /octave) the loudspeaker shall
produce a Sound Pressure Level (SPL) of 89 dB SPL on axis at
1 meter with a power input of 1 Watt, and shall be capable
of producing a peak output of 116.5 SPL on axis at 1 meter.
The loudspeaker shall handle 140 Watts of amplifier power
(AES Standard) and shall have a nominal impedance of 8 Ohms.
The loudspeaker enclosure shall be rectangular in shape. It
shall be constructed of 3/4 thickness medium density fiber-
board (MDF). It shall be finished in black polyurethane. Input
connectors shall be 2-terminal barrier strip. A total of four
1/4”-20 Threaded Mounting Points (1 each top and bottom,
2 on the “outside” side configured to accept an Omnimount
Series 50) shall be provided. The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grille.
The two-way full range loudspeaker shall be the EAW model
UB12Se.
* Data indicate system performance in use with a 24 dB/oct.
high-pass filter set at 90 Hz as is typical in most
professional usage. Operation with the specified 60 Hz high-
pass frequency will yield 100 Watts power handling and a cal-
culated peak output of 115.0 dB SPL @ 1m.
Manufacturing tolerances are +/- 0.13 and +/- 1°
