Description:
Professional cinema has seen a dramatic evolution over the past few years – high definition content, digital projection and immersive audio. These
amazing technologies have put new demands on cinema loudspeakers never before required. This is particularly true for the surrounds. Once a highly
compressed ambience track, surround content today is equal to the screen channels in resolution and dynamics.
Most surrounds are basic loudspeakers, with modest output and simple coverage patterns. They were only used as a large distributed array along the
theatre walls. Digital cinema and new audio formats require surrounds to operate in much smaller groupings and even singularly. This now requires
surrounds to possess engineered coverage patterns and improved output dynamics. JBL undertook an extensive research effort to first analyze these
new requirements and then design a completely new surround loudspeaker, from the ground up, for modern digital formats. The groundbreaking 9300
Series is the result. The horns developed specifically for the 9300 and 9310 have studio quality performance with pattern control tailored to multiplex
theatre geometries. Using the latest advancements in acoustic engineering, the 9300 horns map a theatre more consistently and accurately than
ever before possible. Integral to the design is a wave shaping vane, which distributes acoustic energy in proper proportion to the room. This technique
provides a wavefront that is sculpted to the room geometry and provides very precise mapping capability. This shaping also allows the loudspeaker to
orient to the wall naturally while directing the acoustic energy to the seats.
JBL engineers also found that a slight angle in the positioning of the surrounds makes a dramatic difference in how they present themselves to the
audience. This is particularly true in stadium seating geometry where the surrounds slope downward with the seating, and yet the horizontal patterns in
conventional surround loudspeakers do not. This creates ‘hot spots’ in the coverage for those rows just above each surround. By mounting the surrounds
at a 15° angle toward the screen, the hot spots are eliminated, the overall coverage maps are dramatically improved and those seats in close proximity
to a surround have a much improved experience. The 9300 and 9310 provide three mounting planes for easy installation in any geometry.
