Line Array
Application Guide
EAW Passive Line Array Products - KF810P
Concentric Summation Array
(CSA)
A method of seamlessly
integrating MF and HF
components within a single
horn. With CSA, multiple
subsystems sum coherently,
without interruption to either
HF or MF wavefronts.
Symmetry of Sources
Symmetrical arrangement
of acoustic sources along
a common axis for utmost
consistency throughout
the coverage pattern.
Phase Aligned LF
Tuned
spacing of LF components to
extend pattern control without
the need for enormous horns.
Isophasic Waveguide
Transforms the acoustic
input source to a true
Isophasic output.

NOTES
1 Calculated max SPL at 1m with 4:1 (12dB) crest factor pink noise. Specified as whole space (free field) for full range loudspeakers, half space for subwoofers.
2 Operating Range: Range where the processed Frequency Response stays within -10 dB SPL of the power averaged SPL within this range; measured on the
geometric axis. Narrow band dips are excepted.
3 Nominal Beamwidth: Design angle for the -6 dB SPL points, referenced to 0 dB SPL as the highest level.
4 Accelerated Life Test: Maximum test input voltage applied with an EIA-426B defined spectrum; measured with recommended signal processing and
Recommended Protection Filter.
5 Nominal Impedance: Selected 4, 8, or 16 ohm resistance such that the minimum impedance point is no more than 20% below this resistance over the
Operating Range.
