HOUSTON, Texas – Looking to
upgrade the audio system for the 300-seat auditorium in its Houston
headquarters, CenterPoint Energy recently hired systems integrator AVSIGroup
to install a new audio system for the space featuring HARMAN’s JBL Intellivox self-powered
steerable arrays and JBL AE Compact Series loudspeakers powered by Crown
amplifiers.
“As is so often the case in these projects, aesthetics and performance were the overriding concerns”, said Steve Peters, Technical Sales Executive and System Design for AVSIGroup. “The architect wanted the audio system to be visually discreet, and speakers had to be mounted in the extreme corners of the room — a location that just wouldn’t work for most loudspeakers.”
The room was acoustically
challenging as well, with the floor sloped at such a degree from front to back
that the loudspeakers would be located about 20 feet below the elevation of the
farthest listeners in the back of the
auditorium.
“Looking at the specs, the
Intellivox loudspeakers seemed like they were tailor-made for applications like
the CenterPoint auditorium, where we needed great coverage, powerful output and
a high level of speech intelligibility but had very specific and limiting
restrictions on placement,” Peters noted.
Peters had previously heard the
JBL Intellivox loudspeakers at a local house of worship, where they were
completely hidden from view. “I figured that if the loudspeakers could be made
to work and sound great in a situation like that, they would work well at
CenterPoint,” he said. “Also, the JBL Invellivox DC808 is just a few inches
wide, which made it easy to fit into the design requirements.”
AVSIGroup installed just two of
the Intellivox DC808 loudspeakers, one per side, complemented by a pair of JBL
AC28/26 compact 2-way loudspeakers at the front of the auditorium to provide
downfill for the front rows, along with a JBL ASB6125 dual-15-inch subwoofer and
Crown CDi 4000 and CDi 2000 amplifiers. “I selected Crown amps because they’re
bulletproof and provide me with the appropriate power for a variety of
applications,” Peters said.
JBL Intellivox loudspeakers employ
digital beam steering and shaping technology, in which the phase and relative
amplitude of each of the of the speakers in the array is controlled using DSP
techniques. The DSP also offers a wealth of additional features (volume,
parametric EQ, delay, etc.) and all of these parameters can be controlled from
JBL’s proprietary WinControl software and network connectivity. This
sophisticated digital signal processing enables the speakers to deliver precise
coverage in a manner impossible to achieve using conventional loudspeaker
designs, with an opening angle, aiming angle and focus distance that overcomes
problematic acoustics and overly reverberant rooms, and high volume that belies
the speakers’ slim-profile design.
“The JBL Intellivox system works perfectly—they do exactly what they’re designed to do and enabled us to provide outstanding performance in a challenging situation where we would not have been able to achieve such results otherwise,” Peters said. “The sound is exceptionally clear and smooth from the first row to the back, and CenterPoint is thrilled about how great the room sounds now, this room has gone virtually unused for the past 10 years because the audio was terrible, now it stays booked for various events” Peters concluded.
