This theater is an exercise in what can be achieved in a room of limited size of just 38.3 square meters. In addition the client requested that the installation have the the largest screen possible with seating for 10 people. Equally important was that each of the seating positions have the best possible viewing and listening experience.
Room design
The request for 10 seats meant the matter of bass variation between each seat needed to be overcome. Bearing in mind that equalization of the signal path alone cannot change the seat-to-seat variation, we opted for the physical/mechanical solution of subwoofer arrangement to increase the similarity of the bass performance for each location. Four 15” subwoofers were installed, two in the front wall and two in the rear, which were positioned in from the side walls at a distance of 25% of the total room width..
The mid and high frequency resonances were dealt with by the installation of absorptive and reflective panels onto the walls in line with the first two rows of seats. Subwoofer baffling in the corners, along with two layers of sound board and sound batts through the ceiling and front bulkhead space stopped vibration.
The challenges
The existing space had been halfway developed into a theatre by the previous owner, with cabling in place and some structural work already completed. The decision was made to discard most of this and to rewire and modify the existing space to conform to the more modern anamorphic cinema experience with high definition source material and projector.
The anamorphic screen brought its own issues, with the maximum size that would physically fit being the client’s desire. Careful measurement ensured a good fit was achieved.
The projector and motorised anamorphic lens mechanism were mounted in a custom-made housing which was designed in such a way that it could be easily slid in and out of the bulkhead for service and maintenance.
The decision was taken to locate the majority of the equipment in a rack in the central distribution point of the house, which was located adjacent to the theatre. The exception was the Blu-ray player which was located in the room for convenience. As the two rooms were located next to each other there was no need for any lengthy cable runs, as the cables were routed through the wall. The result was a quiet cinema experience without a rack full of noisy equipment and fans.
Subwoofers were a difficult installation due to the space needed to house them and the subterranean location meant some bedrock and wall had to be cut in order that they fit in the optimum location.
The result
This theatre received the ‘Best Home Theatre $75 – $150K’ at the 2012 CEDIA awards.
