e Crest Audio CPL 5C+is an ultra-compact passive two-way coaxial loudspeaker designed for music playback,
public address and live performance reinforcement applications where space is at a premium.
e CPL 5C+can be utilized for both permanent installations and portable live sound applications. Perfect for
public address, monitoring and background audio reinforcement purposes typically required in houses of
worship, clubs, bars/restaurants, retail outlets plus education and corporate meeting facilities or anywhere high
quality discrete audio distribution is required.
e CPL 5C+is equipped with a premium 5 inch woofer having a 1.5 inch voice coil together with a coaxially
mounted 1 inch exit Neodymium compression driver known for its smooth frequency response and
non-fatiguing mid range. Conical directivity pattern of the loudspeaker is measured at 80° providing a wide yet
well controlled audio coverage. An internal advanced crossover network maintains EQ and driver protection.
Impedance of the loudspeaker is 16 Ohms allowing for easy daisy chaining. Connectivity is made via either
looping 4-pin twist-lock or 4-pin Euroblock connectors.
e CPL 5C+enclosure is built from prime-grade 15 mm plywood that oers sturdy mechanical and low resonant
electro-acoustic characteristics together with a heavy-duty steel grille backed with acoustic foam to ensure
maximum protection of the internal components. e loudspeaker is equipped with a total of 3 threaded
suspension points oering multiple mounting options for various applications. Available in durable black and
white nish.

Conguration: Ultra-compact 2-way coaxial passive speaker
Power Handling*: 100 Watts Continuous, 200 Watts Program, 400 Watts Peak
*To reach the rated power, there must be an infrasonic lter set to 100 Hz, 12 dB / Octave Butterworth minimum ltering. If the CPL 5C+is used with a crossover for a
Subwoofer, then the high pass section needs to meet this criteria at a minimum. A higher frequency and/or lter slope is acceptable.

Before attempting to suspend this speaker, consult with a certified structural engineer. Speaker can fall from
improper suspension, resulting in serious injury and property damage. Do not suspend or mount any other
product or device from this enclosure! Use only the correct mating hardware. All associated rigging is the
responsibility of others. Maximum enclosure angle 30 degrees.
Whenever possible, in addition to the nominal primary mounting method, use a suitable safety chain or wire rope
attached to one of the other groups of fly point inserts, and firmly attached to a suitable structural member as
indicated by a certified structural engineer.
We recommend the use of thread-locker at the insert point bolts, so the bolts cannot vibrate loose. Never
transport the cabinet using the array bracket or other mounting brackets as a structural member, while the cabinet
is mounted on an array bracket or other mounting bracket and unsupported otherwise, as this may unduly stress
the mounting inserts.
This Crest Audio loudspeaker should be suspended overhead only in accordance with the procedures and
limitations specified in the User's Manual and possible manual update notices. This system should be suspended
with certified rigging hardware by an authorized rigging professional and in compliance with local, provincial or
national suspension ordinances.
CAUTION
WARNING
The CPL 5C+coaxial passive 2-way loudspeaker system is very efficient and powerful! This sound system can
permanently damage hearing! Use extreme care setting the overall maximum loudness!
The apparent sound level of the CPL 5C+can be deceiving due to its clear, clean sound output. The lack of
distortion or obvious distress can make the sound level seem much lower than it actually is. This system is capable
of sound pressure levels (SPL) in excess of 118 dB at 1 meter from the speaker!
INSTALLATION
A total of three (3) M8 1.25 mm per thread threaded mounting suspension points (1 top, 1 bottom, and 1 rear) are
provided. The rear one is plugged with a hex key beveled head bolt.
The top and bottom mounting suspension points are for use with the included U-Bracket. The mounting
suspension point on the rear is for use of a forged shoulder machinery eyebolt for a safety chain or wire rope. The
forged shoulder machinery eyebolt should be an M8 size, 1.25 mm per thread, and must conform to at least DIN
580 or ASTM A489, or whatever local, provincial or national suspension ordinances or regulations may
additionally require. Eyebolts must be used at a minimum as a pair, never use just one eyebolt to hang the speaker
overhead.

Diagram 1
Diagram 2
Use the large handled knob-headed bolts to mate the U-Bracket to the cabinet, placing lockwashers between the
bracket and bolt. (See diagram 1 & 2 on page 4). Tighten the knob very firmly to retain the desired angle.
For permanent installations where the cabinet may be within reach of the public, regular hex head bolts can be
used instead of the knob-headed bolts. These should be an M8, grade 8.8 or better, 1.25 mm per thread, metric
bolt, that does not penetrate the cabinet past the cabinet surface more than 20 mm (approximately 3/4”). Metric
M8 steel washers (not supplied) should be used to keep the hex head from pulling through the lockwasher
(supplied rubber gasket).
It is then recommended that thread-locker be used. Using hex head bolts with thread-locker will reduce the
possibility for someone to attempt to unscrew the knob-headed bolts by hand to vandalize or otherwise alter the
cabinets mounting.
To connect a safety chain or wire rope, an M8 eyebolt can be used in the insert point illustrated on page 4 (diagram
2). Specifications for the eyebolt are as follows: A forged steel shoulder-type lifting eyebolt, which meets the
requirements of DIN 580 or ASTM A489, or whatever local, provincial or national ordinances or regulations may
additionally require.
Note: The U-Bracket is a standard accessory, which has been included in the product package.
