How They Did It: Nantucket Cinema

CEDIA
Mar 07, 2016


PMI, Ltd. was dedicated to building their client a sleek, modern home theater with the sound and picture quality of the real thing. So much so that they spent two years developing the room as part of the overall construction of the client’s stunning villa tucked away in the pines of Nantucket, Massachusetts.

PMI, Ltd.’s work was awarded CEDIA’s Best Home Theater Over $500,000 honor at the 2015 CEDIA Awards.



Objectives


The client, a serious audio- and videophile, wanted a state-of-the-art home theater with the highest quality equipment to perfectly replicate the look and sound of the cinema. To give their client the full movie-goer experience, PMI optimized the room’s proportions and materials for standing wave patterns over the frequency range of 20Hz – 150Hz and constructed the wall and ceiling system for STC 65 or better.





The audio package, which includes a Creston Procise PSP-HD surround decoder, Ashly NE24.24 digital audio processor, and LabGruppen studio-grade amplifiers, produces a crisp, dynamic sound, while the Screen Research acoustically-transparent screen and Digital Projection Titan projector with multiple lens zoom and focus provide superior picture quality.

Overall Scope


The comprehensive system PMI built allows the client to control all aspects of his home theater – from sound to picture display to lighting – all from a Creston central matrix, making control simple and easily tailored.




Each configuration, combination, and integration was designed to leave mediocrity behind, giving the client a home theater that would exceed his expectations and standards. On opening night, his first response was, “I love it. I had to hold my breath through most of the movie.”

Mission accomplished.

Compensations


Originally, the space was designed for a flat floor, two-row cinema, which wouldn’t have worked well with the large screen PMI wanted to use. To fix this hiccup, the team reconfigured the entrance, adding an elevated transition deck outside the theater. Additionally, an innovative, lightweight material was used instead of heavy cement to soundproof the room.

Calibrations


To ensure sound quality was up to par, PMI implemented speaker control externally using the Ashly 8x16 digital audio processor, and after testing the sound with a combination of FFT, impulse response, and real-time analysis tools, the room met SMPTE 20M, THX, Dolby Digital, and CEDIA standards.


The video system was configured through all HDMI potential settings, and a color analyzer was used to measure primary, secondary, and grayscale settings.
