DESCRIPTION
I SERIES Subwoofer 800 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.
The compact, low-profile single driver I SERIES
subwoofers are ideal for distributed or concealed
sub-bass and are the perfect choice for ground
stack applications. Additionally, each cabinet was
carefully designed to provide matching face widths
and suspension point locations for seamless
integ ration int o flown array s with I SERIE S full-range
model s when additional LF extension is needed but a
compact appearance is required. The broad r ange 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 IS8-118 is a compact, direct radiating subwoofer
with l arge, balanced ports that provide optimal
enclosure tuning and even air pressure distribution
to the dr iver cones , reducing dis tortion a nd extending
system longevity. FEA optimized linear suspensions
and high flux neodymium motors with long linear
excursion capabilities provide exceptionally deep
bass for the enclosure’s size.
FEATURES
• High-flux, linear neodymium motors with demodulation rings for very low distortion
• Matched-size enclosure and aligned suspension point for seamless flown array integration
• 1600W continuous power handling (6400W peak)
• Long, linear excursion ensures deep, clean bass extension at maximum output
• 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 eects, 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.

4. NOMINAL SENSITIVITY Averaged SPL over the operating
range with an input voltage that would produce 1 Watt
at the nominal impedance and the averaged SPL over
the operating range with an input voltage of 2.83 Volts,
respectively; swept sine wave axial measurements with
no external processing applied in whole space, except
where indicated.
5. NOMINAL MAXIMUM SPL Calculated based on nominal
/ peak power handling, respectively, and nominal
sensitivity; exclusive of power compression.
6. EQUALIZED SENSITIVITY The respective SPL levels
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.
7. EQUALIZED MAXIMUM SPL The SPL produced when an
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
and/or the CLF file from our website: communitypro.com.
CAUTION: Installation of loudspeakers should only be
performed by trained and qualified personnel. It is strongly
recommended that a licensed and certified professional
structural engineer approve the mounting design.
