MY PICK: Yamaha Acoustics Field Control system
PRICING: Quoted on a per-project basis; the most recent system we worked on was $110,000 installed.
WHAT I LIKE ABOUT IT: The AFC system allows truly variable acoustics for multipurpose auditoriums. The system creates convincing natural acoustical character with reverb times up to two times the base condition of the space, with the ability to add early reflections, reverberation, and lateral energy to the seating area. Speakers are virtually invisible hidden in the ceiling clouds fully recessed.
WHAT I WOULD CHANGE: The AFC system is a package that includes AFC AD8HR microphone preamps, AFC 2 processors, Yamaha AFC Speakers, and Yamaha XM 4080 amplifiers.
The speakers are currently the only drawback on some projects. They do not have an all-in-one ceiling retrofit speaker, so the install has to be done from above the ceiling. In some renovations this is difficult.
WHERE I USED IT: Glens Fall High School, Glens Falls, N.Y.
MY RESULTS: The existing space had a reverb time that to some degree satisfied the local professional orchestras that use the space for concerts, but was too live for contemporary music, speech, and theatrical use. There were dead seats in the center of the main floor, due to the lack of physical acoustical diffusion. We corrected the room to a lower RT60 as the base condition using inexpensive absorption.
