Description
The Versarray 218 Sub incorporates the ultra-high power Lo Max 18" woofer
Versarray 218 shown with optional
Ground Stack Kit for mounting three
accompanying Versarray 112 module
loudspeakers (sold separately)
and a new cabinet and vent design. The Versarray 218 is a direct radiator vented
subwoofer designed specifically for the most demanding Pro-Audio applications.
The Versarray 218 Sub is compact for its power handling, SPL output, distortion
performance and bass extension. This is made possible by special characteristics
designed into the Lo Max woofer.
The Lo Max 18" driver is Peavey’s pinnacle of high-power subwoofer design. An incredible 4,800 watt program rating and extralong cone excursion add up to amazing levels of clean, deep bass from a pair of 18" woofers. Incorporating all of the features that
Peavey has engineered into their woofers over the years, including the field-replaceable basket, Kevlar®-impregnated cone for
increased strength and lower distortion due to greater dampening of excess cone vibrations, polyimide-impregnated fiberglass
former for higher sensitivity and extended frequency response, die-cast aluminum frame, and a 4-inch diameter edge-wound voice
coil with solderless diffusion welded OFHC copper leads.
This makes the Versarray 218 Sub a superior choice for the bass end of any high performance sound system, and it is primarily
designed for large professional touring and high performance permanent installs.
Extreme Bracing Cabinet Design
The Versarray 218 Sub cabinet is well braced and very stiff, as internal pressures produced by the Lo Max woofer can be very high.
The vent design integrated into the enclosure includes a middle brace to further increase enclosure stiffness. Each cabinet side
wall and vent wall are tied together at multiple points using multiple interlocking girdle braces, making these some of the sturdiest
subwoofer enclosures on the market. A knuckle-rap test will prove this immediately. The Versarray 218 Sub is constructed of
premium 13-ply Baltic birch plywood and is finished with a durable acrylic polyurethane paint, for a good cosmetic presentation. A
16-gauge powder-coated perforated metal grille covers the front of the system to protect the speakers from external damage. Tilt
back 4" wheel casters provide for ease of transport and set-up.
The Versarray 218 Sub incorporates Peavey’s patented UniVent, covered under US patent #6,549,637. The UniVent venting system
literally pumps air through the enclosure, exchanging the stale hot air inside the cabinet for the cooler outside air. This helps keep
the woofer operating temperatures from getting so high, and increases reliability and reduces power compression under heavy
continuous drive conditions. The air pumping action is achieved without excessive turbulence or any significant net asymmetry
of total vent air flow. The UniVent design integrated into the enclosure includes a middle brace in each vent to further increase
enclosure stiffness. The large vent area and long path length allow for a large volume of air to move with very low resistance. This
is important due to the huge air flow volumes that the Lo Max woofer can produce.
Input connection to the system is made via two 4-pin Neutrik jacks in parallel, or an 8-pin Neutrik jack. A 4-pin Neutrik thru jack
is provided for satellite/top-box bi-amping flexibility while maintaining superior signal integrity. The inclusion of a standard 4-pin
Neutrik jack in parallel allows for daisy chaining to another cabinet. The system comes wired with both woofers in parallel, but
they can be accessed separately by removing the input cup and moving a jumper plug. The two woofers can be driven by separate
power amp channels through the Neutrik input jacks.
Despite its compact dimensions for a double 18" bass enclosure, this system generates extremely high sound pressure levels
(SPLs) and accepts up to 4,800 watts program of clean amplifier power, resulting in large area coverage with excellent punch and
high reliability.

Frequency Response
This measurement is useful in
determining how accurately a given
unit reproduces an input signal. The
frequency response of the Versarray 218
Sub is measured at a distance of 1meter using a 1 watt (into the nominal
impedance) swept-sine input signal. As
shown in figure 1, the selected drivers in
the Versarray 218 Sub combine to give
a smooth frequency response on the
central axis from 46 Hz to 1.5 kHz.
Power Handling
There are many different approaches to
power handling ratings. Peavey rates this
loudspeaker system's power handling
using the AES Standard 2-1984. Using
audio band 40 Hz to 400 Hz pink noise
with peaks of four times the RMS level,
this strenuous test signal assures the
user that every portion of this system
can withstand today's high technology
music. This rating is contingent upon
having a minimum of 3 dB of amplifier
headroom available.
Harmonic Distortion
Second and third harmonic distortions
vs. frequency are plotted in figures 3
and 4 for two power levels. Ten percent
(10%) of rated input power and either
one percent (1%) of rated input power
or one watt, whichever is greater.
Distortion is read from the graph as
the difference between the fundamental
signal (frequency response) and the
desired harmonic. As an example, a
distortion curve that is down 40 dB from
the fundamental is equivalent to 1%
distortion.
Mounting
Caution: This unit is not designed
for overhead suspension!

WARNING! The Versarray 218 Sub is
extremely efficient and handles a
lot of power! This sound system
can permanently damage hearing!
Use extreme care setting the overall
maximum loudness! Due to the clear, clean
sound output of the Versarray 218 Sub and
the lack of distortion or obvious distress,
the sound level seems much lower than it
actually is. This system is capable of SPL’s
in excess of 140 dB at 1 meter from the
speaker!
