MUMBAI: Rock and Roll Hall of Fame and Museum (RRHOF) contains the most comprehensive collection of rock music exhibits and artifacts in the world. Recently, in order to enhance the overall experience for its 400,000 plus annual visitors, the Rock and Roll Hall of Fame and Museum decided to upgrade the loudspeaker system in its main exhibit halls. Following an extensive evaluation, K-array loudspeakers were chosen due to their outstanding audio intelligibility, sound dispersion characteristics and diminutive footprint.
Overcoming a challenging acoustic environment
The museum, which has seven floors and over 150,000 square feet of exhibition space, explores the entire history of the genre through the eyes and ears of the musicians, producers and engineers who made it all possible. One of the primary installation locations is an exhibit called City and Sounds, which takes visitors through different locations and time periods that were instrumental in the evolution of rock music. In addition to priceless artifacts and displays, the exhibit contains plenty of music and interviews to lend first person perspective and insight. Physically, the exhibit environment is a semi-circle, with roughly 20 displays encasements on both sides in addition to seven audio/video exhibits.

“Before installing the K-arrays, we had a lot of unintelligible sound coming from rather important audio sources, as well as a lot of bleed over between the casework,” recalls Raymond Kent, director of the innovative technology design group at system designer Westlake Reed Leskosky. “The previous loudspeakers were pointed out in the space at a rather high SPL and a 90-degree dispersion — effectively throwing sound everywhere. We wanted to provide more focused sound dispersion within each exhibit, while providing greater control over audio bleed into adjacent exhibits.”
KK50vb overview
The KK50vb is a compact line array element comprised of 9 x 2-inch neodymium transducers in a strong stainless steel chassis. The dispersion pattern can be configured for 7-degree â€?spot’ coverage or 120-degree â€?flood’ coverage. The speaker has an impedance of 16 Ohms, eliminating the need for 70-volt transformers in distributed systems.
