Just like the state of Texas, the Galleria Mall in Dallas is huge!
Located at the busiest intersection in Texas, it’s no wonder the Galleria
is called “the most shopped" center in the Dallas-Fort Worth metroplex. Designed
to reflect the feel of the Galleria Vittorio Emanuele in Milan, Italy, the
atrium style super mall includes more than 200 stores and restaurants, anchored
by Macy's, Nordstrom, Saks Fifth Avenue. It also encompasses three attached
office towers, a Westin Hotel and an ice rink.
The Galleria recently underwent a $25 million-plus renovation that included
the complete reconstruction of its centerpiece ice rink. The three-story central
atrium of the mall was extensively reshaped, including construction of new
ceilings and a glass facade. As part of the project, the old ice rink was
completely excavated and rebuilt from scratch.
Omniplan Architects, Inc., and VCC, the mall's general contractor, called
in Fort Worth sound system designer and installation contractor Electro Acoustics
& Video to design a new sound system to serve both ice rink users and the
shoppers in the central area of the atrium. The master plan called for a sound
system that would facilitate live performances by guest artists, pre-programmed
multimedia shows produced by the mall management, and day-to-day music playback
for skaters.
Erich Friend, senior project engineer for Electro Acoustics & Video, said
he set about to design a sound system that would allow the wide, dynamic range
demanded by the mall operations. “During peak holiday sales periods the ambient
noise levels can exceed 90 dBA and during off-season morning hours the levels
can be a modest 40-50 dBA,” Friend said. "So, we had to design a system that
would not interfere with the retail business and restaurants that surround
the rink area while providing a substantial energy level for the reinforcement
of live productions.
When it came to the selecting a subwoofer system, the contractor faced two
major problems. EAVI determined that the only practical location for the bass
speakers would be behind the dasherboards, or sidewalls, of the ice rink.
The concrete perimeter of the rink had already been poured by the time EAVI
was under contract. So EAVI found itself facing twin difficulties: a very
limited amount of space in which to work and the very real problem of high
humidity conditions because of the close proximity to the ice surface.
Chris Jordan, president and owner of EAVI, solved the major hurdle. ”We negotiated
with the general contractor to have some recesses cut into the already formed
concrete perimeter, behind the dasher boards,” he said. “That provided us
with sufficient room to fit some sort of subwoofers.”
“We selected BAG END subwoofers for several reasons, Friend added. “We knew
they would lay down a solid bottom-end that would rock the skaters and drive
the presence of live performance,” he said. “In addition, BAG END engineers
were eager to work with us to develop a custom enclosure that could be integrated
within the limited space behind dasher boards and withstand the humid conditions
near the ice surface.”
Working with Barrington, Ill., loudspeaker manufacturer, Friend selected 10
BAG END S10E-I custom cabinets, each containing one 10-inch subwoofer, to
be placed behind the dasherboards around the rink perimeter. To accommodate
limited depth, BAG END engineers developed a custom cabinet that was only
5 7/8 inches deep, compared to the depth of the standard production model,
which is 11 ˝ inches deep. The custom enclosure was 18 inches high by 15 inches.
Normal dimensions for the standard S10E-I are 12˝ inches high by 14 inches
wide by 11˝ inches deep.
To combat the high humidity problem, BAG END utilized its proprietary outdoor
waterproofing process to seal the cabinet, circuitry and the subwoofer itself
from the elements, in this case, primarily humidity. When used in conjunction
with a BAG END INFRA-M signal processor, as was the case here, the subwoofer
is capable of a flat response down to 18 Hz.
“Completing the sound system, 25 JBL high frequency speakers with stainless
steel grilles are located around the rink perimeter. An additional 26 JBL
ceiling speakers and 19 ceiling subwoofers surround the atrium on each of
the three levels,” Friend said.
“Mall patrons gather at the railings on all levels overlooking the ice during
special events, so the speakers on each level are individually equalized and
delayed so that the composite sound from the rink and the nearby speakers
is consistent,” he added.
The system is driven by QSC CX series power amplifiers, Peavey MediaMatrix
X-Frame88 digital signal processor as well as the BAG END INFRA-M signal processor.
Sennheiser Evolution 300 series wireless microphones, Denon DN-780 dual cassette
deck, Marantz CDR-510 Dual CD player, and Pioneer PD-F908 CD Juke-box provide
the system inputs. Two Rane MP-22Z DJ mixers - one in the central skate rental
office, and the second located in a rink side DJ booth – provide mixing for
the system.
Ultimately, Friend concluded, “The most challenging part of the installation
was scheduling - our crew could only work from 9:00 p.m., after the mall closed
for the night, until 6:00 in the morning, which made for some long nights.”
David Kirby, director of the Galleria ice rink, is very enthusiastic about
the new sound system. “It’s a great sound system,” he said. “We used to rent
sound systems for our shows and they involved a great deal of temporary equipment
and cost us thousands of dollars. Our new, permanent system sounds as good
or better than the big rental systems and is practically invisible.”
When the mall’s renovation was completed, Daniel Upton, regional vice president
for the Galleria’s management company, General Growth Properties Inc., told
the Dallas Morning News, "This is one of the major retail destinations in
the country, and people expect it to be something special. You have to keep
up with customers' expectations, and we've just exceeded that."
