National Arts Centre

Design fulfills contemporary artistic expectations

Engineering Harmonics designed performance sound systems and integrated them seamlessly into a new removable overhead forestage reflector and orchestra shell to support amplified works across a variety of genres in the 2,065-seat Southam Hall that was originally built for opera and ballet, now revisioned for symphonic performances.

EH also designed performance sound systems for several new venues as well as the 710-seat thrust-stage Asper Theatre that is convertible to proscenium mode, inventively incorporating lateral movement in the array rigging to accommodate differing stage widths.


Canada’s premiere marquee, the National Arts Centre includes the beautifully redesigned Southam Hall and Babs Asper Theatre, in addition to several smaller venues and transparent public spaces.


Performance sound, video and communications systems consulting, design, contract administration and commissioning.


The renewal of its 50-year old production facilities has restored the NAC to international standards for artistic expectations, safety and patron experience.



We retained Engineering Harmonics because we respect them and we respect the quality of their work—both the results they had obtained on their previous projects and the process they employed in achieving those results.

The newly installed system has made an incredible difference in terms of coverage, power and fidelity. It has been well received by both touring sound engineers and audience members alike. The quality of the equipment and install have been rock solid for us.

Within an hour they knew where my knowledge stopped and where theirs had to start — and they were very, very gracious about it, even though they play on the world stage. They brought world-class knowledge and home-town service to the project.
