Aspen's Wheeler Opera House Turns to PK Sound for a Near-Invisible Renewal

Jerome B. Wheeler's 1889 opera house is downtown Aspen's crown jewel, and when the City of Aspen set out to replace its twenty-year-old house system, it attached an unusual condition: the new rig had to disappear into the room.

The answer is a PK Sound T8 robotic line source package, deployed from the opera boxes and from under the stage so that nothing intrudes on the Victorian sightlines that make the Wheeler what it is. Aspen City Council approved a professional services agreement with Colorado-based Rockfan Entertainment, LLC to carry out the replacement, with an estimated project cost not to exceed $358,751.20 – selected from six vendor applicants on the strength of demonstrated experience in historic theatres and an integrated design-through-installation approach.

Historic rooms are the hardest brief in performing arts audio, because the usual remedies are unavailable. Acoustic treatment, structural alteration and conspicuous rigging are all off the table in a landmark interior. What remains is the ability to shape where the sound goes – which is precisely what robotic articulation provides.

T8's waveguide is mechanically manipulated to deliver variable symmetric and asymmetric horizontal dispersion across 49 configurations from 60 to 120 degrees, alongside vertical control resolved to a tenth of a degree. That allows tapered arrays tailored to a specific room's geometry rather than a room adapted to a fixed loudspeaker pattern – the difference between steering the Wheeler and rebuilding it.

“We are expecting an improvement in even coverage and quality of sound for all parts of the room with the new equipment and design.”

– Mike Harrington, Executive Director, Wheeler Opera House

Harrington has described the outcome the venue was looking for as “a modern solution that gives us the best possible quality and coverage while minimizing the visual impact and maintaining the room's flexibility and charm” – a summary that captures why a mechanically steerable, physically compact system suited a building that cannot be altered to suit a system.

Work is scheduled around the Wheeler's performance calendar rather than through it, with the venue aiming to have the new system in place during the autumn and the project complete by the end of 2026.
