Control Contractor Coverage - JBL Control 24C Application Manual

Control Contractor Ceiling Speaker Coverage: Following are both the polar and isobar coverage
angles for the Control Contractor Ceiling Speakers:
Model
Control 24C & 24CT
Control 26C & 26CT
Control 19CS & 19CST
Broadband vs. Single-Frequency Coverage Specifications: Some ceiling speakers specify their
coverage only at a particular frequency, -- for example, at 2 kHz -- but the coverage at other frequencies
(1 kHz, 4 kHz, 8 kHz, etc) can be vastly narrower at higher frequencies and broader at lower
frequencies. These types of speakers do not provide even coverage throughout the audio spectrum.
Every spot within the listening area ends up with a different frequency responses and different sound
levels. By contrast, Control Contractor models maintain their specified coverage angles throughout
most of the audio spectrum, resulting in a more consistent tonal character throughout the listening area
and less variation in sound levels.
