Technical Specifications UB12
APPLICATIONS
The UB12 is purpose-designed for background/surround applications
where sound quality cannot be sacrificed for the sake of visual
unobtrusiveness. It is also an excellent choice for nearfield reproduction
where extreme low frequency response is not required. Ultra-compact
design and surprisingly high output make it an effective component of
large-scale multimedia systems in a broad range of venues and applica-
tions.
This “micro” system is engineered for high quality distributed sound
systems of all types. The vented enclosure extends effective low fre-
quency response. A 1" soft dome tweeter produces exceptional clarity
and definition. The complex crossover uses computer-optimized asym-
metrical filters to smooth on-axis frequency response as well as power
response.

The two-way full range loudspeaker system shall incorporate one 5.25-
inch cone low frequency transducer and one 25mm soft-dome high
frequency transducer. The total system shall meet the following perfor-
mance criteria: Frequency Response of 100 - 18k Hz ±3 dB; Axial Sensi-
tivity (1 W @ 1 m) of 91 dB SPL (LF); 100 hour sine wave Power Han-
dling of 90 Watts, AES method Power Handling of 180 Watts; Hori-
zontal coverage of 120 degrees between 6dB down points; Vertical
coverage of 120 degrees between 6dB down points.
The system’s low frequency driver shall be loaded into a vented enclo-
sure that provides optimally controlled acoustic diaphragm loading. An
internal passive frequency dividing network shall provide a fourth order
acoustic crossover between the low and high frequency subsystems
and shall incorporate system equalization. The crossover shall be de-
signed so that maximally flat frequency response is obtained.
The enclosure shall be rectangular in shape and constructed of void-
free cross-grain-laminated birch plywood with internal bracing. It shall
be finished in a black catalyzed polyurethane coating. The front of the
system shall be covered with a protective perforated steel grill assembly
coated with vinyl to dampen resonance. Mounting hardware attach-
ment points shall be located on the top and bottom of the enclosure.
Attachment points for Omnimounttm brand 75 series mounting hard-
ware shall be located on the rear of the enclosure.
The two-way full range loudspeaker system shall be the EAW model
UB12.
