Foothill Ranch, CA – (December 2008) A high powered Renkus-Heinz ceiling loudspeaker system is at
the heart of a unique acoustical solution for a large, multi-purpose dividable lecture room at the Great Hall
of the Centre for Continuous Learning at Mount Royal College in Calgary, Alberta.
The Great Hall is a LEED® (Leadership in Energy and Environmental Design) Green Building Rating
System™ energy efficient design with exposed concrete surfaces that warm up and then release the
stored energy back into the building.
The room being walled in concrete with tall glass windows posed a
tough challenge for consultant Fred Gilpin
and local contractor Apex Audio Visual
The room can be used either as a single large space or can be reconfigured as two or three smaller
seminar rooms by giant brushed stainless steel room dividers. Either way the space presents a battery of
hard, reflective surfaces. A single audio system was required to serve the needs of both configurations
and, the design brief called for high quality vocal reinforcement for lectures as well as moderate music
playback of pre-recorded sources. Additionally, the complete system is capable of 5.1 surround sound for

by Renkus-Heinz Application Engineer Jonas Domkus
to devise a radical design, deploying Renkus-Heinz CS-66
Entrant loudspeakers mounted on the ceiling and adjacent to each projection screen. This allowed the
three separate areas to be driven independently or as one space. The multi-driver Co-Entrant technology
delivers the high SPLs and directivity necessary to achieve good intelligibility from the 30 ft ceiling height.
The system is under DSP control and programmed so the acoustic image can be located to whichever of
the five video screens are being used around the space. When the room is used fully open, the audio
image shifts to the screen at one end, with the rest of the loudspeakers providing timed delay fills.
Says Gilpin, “The primary reason for choosing the CS Series loudspeakers is the pattern control they
provide down into the lower frequencies of the vocal range. The multi-driver Co-Entrant technology
delivers the high SPL required by the 30 ft ceiling height and allowed us to keep virtually all of the sound
off the exposed hard surfaces. The CS Series speakers are providing a high degree of intelligibility in an
extremely challenging acoustical environment.”
“In the Faculty of Continuing Education & Extension we talk about the power of possibility that education
can bring to people’s lives,” said Norma MacIntosh, Dean of the Faculty of Continuing Education &
Extension. “The Centre for Continuous Learning will help Mount Royal turn possibility into reality for
thousands of learners.”
