Port Perry, Ontario (December 6, 2013)—Located in a suburb of Melbourne, Australia, the Hawthorne Town Hall has acted as a library, museum and gallery space since 1994, and is now undergoing a redevelopment into the Hawthorne Art Centre. As part of this redevelopment, a new Adamson Metrix-I line array system with Metrix Sub-I dual 15-inch subwoofers was installed to the venue’s main hall and chandelier room.
The final system designs were created and optimized by Simon Tait of CMI, who also commissioned and tuned the systems.
Hanson and Associates, the consultant on the project, set criteria for the new system that includes a minimum STI (Speech Transfer Index) of 0.6 coupled with a +/-3 dB variance between 80 Hz and 15 kHz across the entire listening area. Installation of delay zones was not feasible for aesthetic reasons, therefore the entire throw in the room (approximately 100 feet) had to be accomplished using only the front arrays.
Tait specified main arrays each comprised of eight Metrix-I enclsoures flown left and right, with Metrix Sub-I subwoofers also provided for applications requiring enhanced low end. The only additional loudspeakers in the system are attached to the face of the stage to bolster coverage to the front seating rows. Rutledge AV installed the system under Project Manager Daniel Woodward.
The chandelier room is a much smaller space that accommodates up to 200, depending upon how the room is used. Two left-right arrays, comprised of 4 Metrix-I enclosures, were installed above the small balcony in the room. The new systems are powered by MC2-T1500 amplifiers in bridged mode for the subs, MC2-T3500 for mids and MC2-T1500 for HF. Speaker management is performed by a group of four XTA-DC1048 processors.
