There are many ways to approach
building transducers, but Precision
Devices knows of only one: an
unremitting desire for excellence.
Our quest for excellence ensures that
all Precision Devices’ transducers are
imbued with quality from the first
computer simulations by our Research
and Development team to the final
product off the production line.
Precision Devices transducers are
individually hand-built in England
to our exacting specifications
and no compromise to quality is
made in the interest of facilitating
ease of assembly. A Precision
Devices transducer is the product
of assiduous care in all stages
of manufacture from the initial
blueprint to the end product. Each
Precision Devices transducer is
carefully crafted to give the highest
levels of reliability, performance and
tonal distinction.
With our roots firmly in the touring
sector, it is not surprising that we
are a firm favourite with many of the
world’s finest touring companies
providing both front of house and
monitor sound equipment for
internationally renowned artists and
performing venues worldwide. In a
market in which rugged reliability
is prized as an essential selection
criterion, Precision Devices are built
to thrive, not just to survive,in the
most demanding of environments.
We welcome the opportunity of
working with OEMs and –subject to
quantity – offer a custom service of
bespoke transducers built to your
exacting and demanding design
brief. Our skilled technical staff and
dedicated engineers are available to
manufacture custom units that are
correct first time, on time and with
the least variation from your original
specification.
The world wide reputation for high
quality performance, reliability
and ruggedness is no accident: it
is the result of our no-compromise
approach to delivering quality, our
commitment to providing world class
customer service and our unceasing
quest to ensure that our products
are at the forefront of engineering
development in the audio industry.
We are dedicated to providing
our clients with complete product
satisfaction and we are proud to
have our products used by many
of the world’s premier loudspeaker
companies.
Precision Devices,
The Professionals Choice.
.Precise Performance
All our loudspeakers are designed using the finest materials without compromise.
They are manufactured in our factory in the North of England by our skilled team that
have many years of experience in building high quality audio components.
Chassis
Cones
Our unique twelve sided chassis
are manufactured using diecast
aluminium alloy with added sectional
strength, often twice as thick as most
manufacturers. The result is a range
of drive units that won’t fail even
under massive physical shock.
The cones also made in England
are carefully inspected prior to
use to ensure they are within fine
set tolerances. This ensures the
exact sound quality will be found
throughout the series.
The unique design, ensures that
the fixing holes used to house the
speaker into the cabinet are a good
distance from the baffle hole in the
cabinet. This ensures that should the
cabinet be dropped there would be
no splitting between the holes and
the baffle.
• Thick section chassis to ensure
maximum heat transfer away from
critical areas
• Many chassis feature additional
“hidden” mounting holes to allow
maximum flexibility of installation
• Extra wide flange prevents
unwanted pressure from out of
position fixing from distorting the
chassis
• Long fibre designs for improved
internal damping and extra tear
resistance
• Air dried for optimum tonal
qualities
Magnet Assembly
The magnet assembly is the engine
of the speaker and only the finest
materials are used. The plate sets
are precision machined in Sheffield,
England using top quality low
carbon steel selected for its magnetic
properties.
The anisotropic ceramic magnets
are tested to exacting tolerances
to ensure the highest BL factors. All
magnets are tested to withstand the
extremes of working temperatures
without loss of flux. This is very
important where speakers can be
used in freezing temperatures and
also be driven to extremely high
temperatures.
The fine machining tolerances of
the plate sets ensures the strongest
possible bond between magnet
and plate set further increasing
the magnetic strength. The tight
tolerances used in the magnetic
gap also increase the cooling for the
voice coil.
• Precision CNC machined for
closest possible tolerances which
minimizes variation
• Strongest adhesives available
are utilised for maximum shear
strength, selected for their bond
properties and never for speed of
cure
• Magnetized using our 100K
Joule magnetizer to ensure total
magnetization
Voice Coils
Suspensions
Assembly
The voice coil is the heart of the
speaker. We are producing a range
of voice coils from 38.1mm (1.5”)
to 152.4mm (6”)using both copper
and aluminium wire. The wire is
coated with high temperature
enamel, and precision wound onto
an epoxy resin-impregnated woven
fibreglass former. This is then cured
in a precise temperature controlled
oven to ensure a rigid assembly that
is essential for greater strength and
to maximise its energy transmission
abilities.
• Poly cotton material for maximum
strength and longevity
At the end of this chain is the vital step
which guarantees that all the effort
we’ve put into the design is reflected
in the manufacturing quality.
• Material properties selected for
optimum strength, adhesion and
longevity
Terminals
All models use metal push terminals
as standard to ensure a perfect
termination without the requirement
of soldering.
Dust Caps
• Laminated construction for
maximum strength
All models use a solid composition
centre dome and work as an extension
of the cone, giving a greater cone area.
• Wet wind process used on all our
coils,a key process in which we
have chosen component integrity
over production speed
• Made from long fibre pulp and
on processes optimised for sound
quality and never for speed of
production
• Our proprietary coil design/
process, which we have developed
in-house, is carefully optimised
to give maximum strength and
longevity. No compromise has ever
been considered just to deliver
short-term gain
• Close tolerance wires are sourced
for minimum unit to unit variation
All components are assembled by a
modular process, and each module is
then individually tested before being
assembled into a complete unit.
The result is a more accurate natural
sound and improved reliability,
through precisely-designed and
manufactured components.
• All processes and adhesives are
chosen for their thermal and
mechanical properties and never
for speed of cure
• Built using a carefully controlled
blend of operator controlled and
automated processes with in-built
operator inspection at each key
stage
• All units are produced in our
custom built facility which was
designed by our team from a blank
canvas to optimise all aspects of
production.

1. AES Standard (40 to 400 Hz) Program 1200 Watts.
2. Sensitivity is derived from the sine wave response between 60 - 450 Hz at 5W/2M using
Zmin. It should be noted that not all manufacturers’ sensitivity figures are based on this AES
Recommended Practice.
3. In less demanding applications, the crossover point may be higher.
4. Thiele - Small Parameters follow a 600 Watt preconditioning period.
*1 Power compression is the reduction of sensitivity at the specified power. Higher
power ratings do not necessarily give a proportionate increase in SPL, therefore the
maximum SPL of the PD.1550 may significantly exceed that of other manufacturers
with high published power ratings.
*2 Distortion is measured at 10% of the rated power (AES standard)

achieved with other, more conventional, 15” transducers.
A popular choice for stage wedges when a faster mid range
attack is required.
Also suitable for bass guitar.

PD.123ER
Perfectly suited to either direct radiating or popular horn
loaded mid/high applications, the extended frequency range
makes this unit an excellent choice where a small format
high frequency unit dictates a higher crossover point than
would be achievable with other, more conventional, 12”
transducers.
A very popular choice for stage wedges when a faster midrange attack is required. Also suitable for vocal performances
as the PD.123ER covers the critical vocal range in a single,
highly effective unit.

PD.122
Medium resonance 400 WRMS bass driver with a smooth
response down to 40 Hz in a reflex enclosure, the PD.122 is
an ideal selection when building/re-furbishing stage wedges.
Well suited for use in small compact full range systems in
combination with 1” or 2” compression drivers.
An excellent choice for compact/portable systems where the
powerful bass response eliminates the need for a dedicated
sub woofer where circumstances do not allow for a separate
18”, 21” or 24” unit.

*1 Power compression is the reduction of sensitivity at the specified power. Higher
power ratings do not necessarily give a proportionate increase in SPL therefore the
maximum SPL of the PD.2450 may significantly exceed that of other manufacturers with
high published power ratings.
*2 Distortion is measured at 10% of the rated power (AES Standard).

Delivers faultless low end performance in applications in
which others fall by the wayside. Perfectly at home in new
or refurbished horn loaded sub bass systems this unit also
delivers powerful lows in reflex designs.
An outstanding drive unit since it allows designers
considerably more freedom with enclosure design and
specialised loading techniques without having to allow for
physical characteristics or power handling limitations which
are typically the result of more traditional designs.

1. AES Standard (30 to 300 Hz) Program 2000 Watts.
2. Sensitivity is derived from the sine wave response between 50 - 350 Hz at 5W/2M using
Zmin. It is then scaled to represent 1W/1M. It should be noted that not all manufacturers’
sensitivity figures are based on this AES Recommended Practice.
3. In less demanding applications, the crossover point may be higher.
4. Thiele - Small Parameters follow a 1000 Watt preconditioning period.
PDN.2151
The PDN.2151 is a unique high power, high efficiency cone
transducer designed specifically to provide powerful and
accurate sub bass frequencies with minimal distortion and
power compression.
power ratings do not necessarily give a proportionate increase in SPL, therefore the
maximum SPL of the PDN.2151 may significantly exceed that of other manufacturers
with high published power ratings.
*2 Distortion is measured at 10% of the rated power (AES Standard).

PDN.18SB40
Designed to provide faultless performance when used in
either horn-loaded or bass reflex enclosures where fast
accurate lows are demanded.
Neodymium technology ensures superb versatility in
situations in which a conventional ceramic magnet
transducer is unsuitable on grounds of portability or ease of
installation.
An exemplary choice for upgrade or replacement situations
where the capability of the PDN.18SB40 to “drop in” and
provide outstanding bass response makes this a versatile and
highly effective unit.
Well suited to use with PDN.10MH25/ PDN.12MH25 and
complimented with 1” or 2” compression drivers in direct
radiating/horn loaded systems where the double suspension
system allows it to thrive in the demanding touring sector.
