EU™

218 Sub

Description

™

The EU

218 Sub incorporates dual
lightweight Neo magnet 18” woofers
and a new compact cabinet design.

™

The EU

218 Sub is a vented isobaric
subwoofer designed specifically for the
demanding Pro-Audio user.

™

The EU

218 Sub is compact for its
power handling, SPL output, distortion
performance and bass extension.
This is made possible by the isobaric
cabinet design and the neodymium
based woofers.
The Pro Plus 18 Neo magnet woofers
in the EU

™

218 Sub cabinet, in
conjunction with the premium 9 ply
18mm ultra-light plywood, allow for a
light-weight dual 18 inch system,. It is
finished with Peavey’s tough Hammer

™

polyurethane finish, for good

Head
looks and durability. A full-length
16 gauge powder-coated perforated
metal grille covers the front of the
system to protect the speakers from
external damage. The grille is lined on
the inside with a polycloth fabric for a
good cosmetic presentation.

™

The EU
patented UniVent

218 Sub incorporates Peavey’s

™

, covered under US
patent #6,549,637. Normal vented
enclosures merely pump the same slug
of air back and forth, and any cooling
is incidental. 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 UniVent

™

air pumping action is
achieved without excessive turbulence
or any significant net asymmetry of
total vent airflow.
Input connection to the system
is made via two 4-pin twist lock
connectors in parallel. The inclusion of
a pair of standard 4 pin Neutrik

®

jacks
in parallel for the main inputs allows
for daisy chaining to another cabinet.
A pole tunnel is built-in so that a
full-range speaker system can be
mounted up high above the subwoofer
cabinet for optimal venue coverage.
Despite it’s extremely compact
dimensions and light weight for a dual
18” bass enclosure, this system can
put out some serious sound levels,
and take 1,600 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 EU

™

218 Sub
is measured at a distance of 1-meter
using a 1 watt (into the nominal
impedance) swept-sine input signal.
As shown in figure 1, the selected
drivers in the EU

™

218 Sub combine to
give a smooth frequency response on
the central axis from 44 Hz to 375 Hz.

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 pink noise with a
bandwidth of 40 Hz to 400 Hz, and
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
& 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!

Architectural & Engineering
Specifications-

The loudspeaker system shall have
an operating bandwidth of 44 Hz to
375 Hz, measured on axis at 1m in an
anechoic environment, with +/- 3 dB
tolerance. The nominal output level
shall be 96 dB when measured at a
distance of one meter with an input
of one watt. The nominal impedance
shall be 4 ohms. The maximum
continuous power handling for a single
cabinet shall be 800 watts, maximum
program power of 1,600 watts and a
peak power input of at least 3,200
watts, with a minimum amplifier
headroom of 3 dB. The outside

dimensions shall be 22.75 inches high
by 27.00 inches wide by 24.50 inches
deep. The weight shall be 76 pounds.
The loudspeaker system shall be a
Peavey model EU

™

218 Sub.

WARNING!: The EU™ 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 EU

™

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 136 dB at
1 meter from the speaker!

Speaker Cables

For best results, do not daisy-chain
the speaker cable runs, or use small
speaker cables to power the EU
Sub, run a single dedicated speaker
cable to each EU

™

218 Sub.

™

218

A minimum of 12 ga. Speaker cable
is recommended, to help maintain
damping factor, and due to the high
amount of power that will be sent
to the EU

™

218 Sub. If the speaker
cable run is longer than 50 feet, we
recommend locating the power amp
nearer the EU

™

218 Sub, and running a

line level signal out to the power amp.

Crossover Settings

A number of suitable crossover options
are available from Peavey: the Peavey

™

26 Loudspeaker Controller, the

VSX

™

48 Loudspeaker Controller, and

VSX
the Peavey Digitool

™

MX. These have
available pre-configured set-up files
that provide an optimized crossover,
and EQ for a flat response and level set
as a starting place for any permanent
installation.
