Community WET II - Operation and Installation Manual - Page 13
GENERAL DESCRIPTION
WET II loudspeakers are designed for top-of-the-line installation work. Their premium components are
housed in rugged, uniquely shaped curved enclosures that are acoustically inert. WET II systems are
characterized by high power and low distortion, with exceptional musicality and speech intelligibility.
The WET II line comprises six form-factors, three of which may be ordered with a choice of horn patterns.
The four smaller models may be ordered with an internal 70V/100V autoformer for constant voltage
applications, and all models are available in either a black or white finish. Custom colors are also available;
prices will be quoted upon request. Three models of WET II subwoofers round out the line, providing
extended bass response for foreground music applications.
HIGH-PASS FILTERS
We strongly recommend the use of an external, active high-pass filter to protect the cone drivers from
excessive low frequency excursion. Additionally, a high-pass filter will avoid wasting amplifier by
attempting to reproduce frequencies below the loudspeaker’s intended operating range. The recommended
filter settings are as follows:
Model High-Pass Filter
W2-218 70 Hz, 24db/octave
W2-228 60 Hz, 24db/octave
W2-2W8 60 Hz, 24db/octave
W2-215 50 Hz, 24db/octave
W2-312 55 Hz, 24db/octave
W2-322L 40 Hz, 24db/octave
W2-315 60 Hz, 24db/octave
W2-112 50 Hz, 24db/octave
W2-122 45 Hz, 24db/octave
W2-125 30 Hz, 24db/octave
Many modern DSP loudspeaker controllers or loudspeaker management devices can provide the required
high-pass filter mentioned above, as well as general equalization to correct for room response problems,
digital delay to correct for timing differences among multiple loudspeakers, as well as other DSP ‘tools’ that
can help solve acoustic anomalies. Such devices can also be used as protective peak limiters to protect the
system from damage, as further described below.
