OPAL-I The OPAL is a full range, compact, long throw loudspeaker system offering high fidelity, high efficiency and high
power handling capacity. The OPAL is designed for applications
where high sound pressure and highly directive long throw capability are required. The OPAL-I includes permanent rigging attachment points and three forged steel eyebolts. Units are designed
to use the Bag End yoke (YOKE-1) or, for large arrays, ATM
Flyware™. Constructed from 18 mm 13-ply birch plywood and finished in black textured lacquer, the OPAL-I enclosure is durable
and attractive. In addition, weatherproofing options are available.

About Time Align® Time Align® assures that the fundamental
and overtones of a complex, transient, acoustical signal are presented to the listener in the same relationship as the electrical
signal at the input terminals of the loudspeaker.
The conventional loudspeaker spreads out the sound in time:
when a rapid series of transients occur the results are blurring
and lost detail. With Time Align®, a transient is presented as a
tight package of energy, with the same time relationships as the
natural sound. This means that a rapid series of transients will
be heard clearly.
True Time Alignment™ requires much more than just physically
lining up the loudspeaker components. It requires consideration
of the driver placement, driver delay and adjustment of the
crossover delay parameters. This achieves the precise simultaneous acoustical arrival time of each driver throughout the
crossover region.
Along with state-of-the-ar t laborator y instruments, the proprietar y Time Align® generator, built by Ron Wickersham, is used
in designing our loudspeaker systems. The Time Align® generator is founded upon different underlying mathematical principles than are used in the more common Fourier based measurement equipment.
When comparing a genuine BAG END Time Aligned™ speaker
system to any other, our additional design work is easy to hear
and appreciate. The dramatic clarity, realism, and overall pleasant sound of our Time Aligned™ loudspeakers is noted throughout the world.

ARCHITECTURAL
SPECIFICATIONS
The loudspeaker shall be a 2-way vented type system with one low frequency
driver and one high frequency compression driver with horn. The low frequency
driver
shall
be
300 mm (12") with a 2.7 kg (95 oz.)
magnet and a rear vented back plate
assembly. A 76 mm (3") copper voice
coil wound on Kapton former shall be
coupled to a 70F cone. The high frequency driver shall have a titanium
diaphragm coupled to a 76 mm (3")
copper voice coil driving a fiberglass
elliptic conical horn. System dispersion
of a single unit shall be 55O horizontally by 40O ver tically at the
-6dB points. Units shall array for wider
horizontal dispersion. The frequency
response shall be 95 Hz to 18 kHz ±3
dB.
The
system
shall
be
Time-Aligned™ by E. M. Long
Associates with a time offset at
crossover of <±25 microseconds. The
system shall have an average sensitivity of 100 dB SPL with 1 Watt input
at 1 meter. The system shall have a
minimum power handling of 600 Watts
continuous program long term. The
enclosure shall be made of 18 mm
(3/4") thick 13-ply birch plywood with
glued rabbet joints and internal bracing. The enclosure shall be internally
dampened with 125 gram/inch2 cotton
acoustic treatment. The enclosure
shall have rigging attachment points.
The protective grille shall be powder
coated 14 gauge perforated steel with
a welded aluminum frame. The input
connector plate shall be recessed in
the back of the enclosure and shall
include one Cinch 142 screw terminal
barrier strip. Overall dimensions shall
not exceed 61 cm (24") h x 36 cm
(14") w x 41 cm (16") d. The unit shall
weigh no more than 31 kg (68
pounds). The unit shall be completely
painted with durable black textured
lacquer.
