Do Not Disturb
Briefly describe the objectives in creating this theater.
Among the client’s objectives were seating for at least eight, the ability to use the theater loudly without distress to other family members, a high quality audio and video experience, and an interior which matched the decor of his basement. Finally, the room must achieve THX Certification.
The designated theater area shared walls with his wine room, and the home’s mechanical room, and the master bedroom was directly above. Sound isolation was going to be a challenge. The basement decor utilized elaborate mahogany woodwork which needed to be carried into the theater area - none of which were conducive to creating an outstanding audio and video playback space.
What technical features are notable in this project?
A Crestron control system was installed to simplify the use of the equipment servicing the room, manage room lighting, and administer the dedicated HVAC system servicing the room. High mass materials, constrained layer dampening, and mechanical isolation were used on the walls, ceiling, and floor to create a sound isolation envelope.
All trim, acoustic materials, platforms, and stage were installed inside that envelope, and a THX certified door was installed for the entry. Acoustic materials included specialized diffusion and absorption products some of which were internally designed for this space. The large 2.35:1 screen was slightly curved to reduce reflections on the side walls and help to meet the very difficult 150:1 in room ANSI contrast ratio requirement.
To reduce seat to seat variance in sound, a total of six Procella P8 surround speakers were installed, the seating platform designed to function as a base trap, the rear radius portion of the room was used for low frequency and low midrange control, and multiple THX certified QSC DSP322UA signal processors were used to manage the five subwoofers and the side speaker array. The design of the solid mahogany ceiling facilitated high and mid-frequency diffusion while also preventing image reflections from the ceiling.
