Sunway Resort Hotel & Spa, located about 14.5 km southwest of the Malaysian capital of Kuala Lumpur, recently upgraded to a Renkus-Heinz sound system for its Grand Lagoon Ballroom. The ballroom accommodates 2,000 guests for events.
The ballroom can be divided into three separate halls; the middle of these includes an extendable stage. The sound system needed to serve each of the three sub-ballrooms individually and still quality sound when the rooms were united. System designer and distributor Mercoms Systems Sdn. Bhd., chose Renkus-Heinz CFX-series loudspeakers for the job.
Keith Tan of Mercoms Systems Sdn. Bhd. said: “The ceiling is at least 7m. The walls are mostly made of wood frames with some soft cloth-wrapped padding in the middle and glass mirrors at the top, and the floor is carpeted. So although the ballroom has some glass surfaces, it also has absorptive surfaces, and there are no pillars. But the depth of the ballroom was a challenge. It was vital to be able to throw clear sound all the way to the rear while achieving relatively even coverage. That made the CFX series an obvious choice."
For Ballroom 2 (the middle ballroom with the stage), Tan flew a left-right pair of arrays, each with four CFX-101LA modular point-source arrays and two CFX15S subwoofers. CFX101LA cabinets can be arrayed to provide a 90x60-degree coverage pattern, delivering up to 9 dB more output and tighter vertical pattern control than a conventional single cabinet. It delivers the performance and pattern control of a line array with the clarity of a point-source system. Choosing the CFX-101LA enabled Tan to cover the room with a third to half the number of cabinets required with traditional line arrays.
The CFX15S is a passive subwoofer with a powerful 15-inch driver that delivers outstanding sub-bass performance from 40 Hz to 100 Hz and delivers up to 128 dB peak SPL.
When partitioned, each of the two smaller, adjacent ballrooms are served by left and right arrays consisting of four CFX-101LA full-range systems and one CFX-15S. All of the speakers are flown from the ceiling. A Biamp Tesira server provides speaker management, including crossover settings and EQ, and combines the systems when the partitions are open.
