TECHNICAL SPECIFICATIONS UB12S

DESCRIPTION

A 2-way full range system (passive LF/HF crossover) in an
ultracompact vented rectangular enclosure. Includes a 5.25­in woofer and a 3/4-in soft dome tweeter. Magnetically
shielded for use in immediate proximity to video monitors.

APPLICATIONS

The UB12S provides surprisingly high output and reliability
from a mini-monitor. Magnetically shielded for use in imme­diate proximity to video monitors. 1/4"-20 threaded mount­ing/suspension points allow permanent installation. Six year
warranty.

Applications include:

Ballroom Events
MultiMedia
Boardrooms
Restaurants
Small Retail Spaces

ARCHITECTURAL SPECIFICATIONS

The two-way full range loudspeaker systems shall incorpo­rate a 5.25-in LF transducer a 3/4-in HF transducer.

The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The system shall have

a nominal coverage pattern of 120° (conical). An internal

passive filter network shall provide fourth order acoustical
crossover and system equalization. The drivers shall be mag­netically shielded allowing the systems to be used in imme­diate proximity to video monitors.

System frequency response shall vary no more than ±3 dB

from 98 Hz to 20 kHz measured on axis. 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 and
shall be available in left/right mirror-imaged pairs. It shall
be constructed of 3/4-in medium density fiberboard (MDF)
and shall employ extensive internal bracing. It shall be fin­ished in black catalyzed polyurethane. Input connectors shall
be 2-terminal barrier strip. A total of four 1/4”-20 threaded
mounting/suspension points (1 each top and bottom, 2 on
one side to accept Omnimount Series 25) shall be provided.
The front of the loudspeaker shall be covered with a vinyl
coated perforated steel grill.

The two-way full range loudspeaker shall be the EAW model
UB12S.
