DESCRIPTION

I SERIES Subwoofer 600 loudspeakers provide
exemplary acoustic performance, modular flexibility
and elegant aesthetics for modern per formance
venues. Designed to support the goals of s ystems
integrators and consultants both acoustically and
mechanically, I SERIE S Subwoofers provide a broad
range of sizes and capabilities that can be specifically
matched to the needs of any modern venue.

Each cabinet was carefully designed to provide
matching heights, face widths and suspension point
locations for seamless integration into flown arrays
with I SERIES full-r ange model s. The broad range of
optional low profil e fly rails, fly f rames and modular
array brackets reduces design and installation time
while also providing improved aesthetics and nearly
limitless integration possibilities.

The IS 6-218 is a direc t radiatin g subwoofer w ith large ,
balanced port s that provide optimal enclosure tuning
and even air pressure distribut ion to the driver cones,
reducing distortion and extending system longevity.
Drivers are loaded into individual air volumes within
the enclosure, isolating their performance from
one another. This arrangement not only provides
additional protection to drivers in case of failures,
but al so allows th e designer to im plement dire ctional
subwoofer techniques, like steered end-fire arrays
and cardioid patterns, within a single enclosure when
using any I SERIES dual dr iver subwoofer model.

FEATURES

• Long excursion ferrite LF drivers with FEA-optimized motors and symmetric movement suspension

• Matched-size enclosure and aligned suspension point for seamless flown array integration

• 1400W continuous power handling (5600W peak)

• High sensitivity design minimizes power compression losses and required amplifier size

• Isolated driver air volumes allow use of directional steering techniques within a single enclosure

NOTES

1. PERFORMANCE SPECIFICATIONS All measurements
are taken indoor using a time-windowed and processed
to eliminate room eects, approximating an anechoic
environment, a distance of 6.0 m. All acoustic
specifications are rounded to the nearest whole number.
An external DSP with settings provided by Community
Professional Loudspeakers is required to achieve the
specified performance; further performance gains can
be realized using Community’s dSPEC226 loudspeaker
processor with FIR power response optimization.

2. OPERATING RANGE The frequency range in which the
axial processed response remains within 10dB of the
average SPL.

3. CONTINUOUS POWER HANDLING Maximum continuous
input voltage (and the equivalent power rating, in watts,
at the stated nominal impedance) that the system can
withstand, without damage, for a period of 2 hours using
an EIA-426-B defined spectrum; with recommended signal
processing and protection filters.

produced when an EIA-426-B signal is applied to an
equalized loudspeaker system at a level which produces
a total power of 1 Watt , in sum, to the loudspeaker
subsections and at a level which produces a total voltage,
in sum, of 2.83 volts to the loudspeaker subsections,
respectively; each referenced to a distance of 1 meter.

EIA-426-B signal is applied to an equalized loudspeaker
system, at a level which drives at least one subsection to
its rated continuous input voltage limit, referenced to a
distance of 1 meter. The peak SPL represents the 2:1 (6dB)
crest factor of the EIA-426-B test signal.

8. AXIAL PROCESSED RESPONSE The axial magnitude
response of the complete loudspeaker system and each
pass band capable of being driven by an independent
amplification channel with recommended signal
processing applied. 1/6 octave smoothing applied.

9. AXIAL SENSITIVITY The SPL plotted against frequency,
in all operating modes and for each pass band capable of
being driven by an independent amplification channel, for
a 1 Watt swept sine wave, referenced to 1 meter with no
signal processing. 1/6 octave smoothing applied.

Data presented on this spec sheet represents a selection of
the basic performance specifications for the model. These
specifications are intended to allow the user to perform a
fair, straightforward evaluation and comparison with other
loudspeaker spec sheets. For a detailed analysis of this
loudspeaker’s performance, please download the GLL file
