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.

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

ChassisOur 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 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.

• Thicksectionchassistoensuremaximum heat transfer away from critical areas

• Manychassisfeatureadditional“hidden” mounting holes to allow maximum flexibility of installation

• Extrawideflangepreventsunwanted pressure from out of position fixing from distorting the chassis

ConesThe 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.

• Longfibredesignsforimprovedinternal damping and extra tear resistance

• Airdriedforoptimumtonalqualities

Magnet AssemblyThe 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 toensure thehighestBL factors.Allmagnets 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.

• PrecisionCNCmachinedforclosest possible tolerances which minimizes variation

• Strongestadhesivesavailableare utilised for maximum shear strength, selected for their bond properties and never for speed of cure

• Magnetizedusingour100KJoule magnetizer to ensure total magnetization

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.

.Precise Performance

Voice CoilsThe 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.

• Laminatedconstructionformaximum strength

• Wetwindprocessusedonallourcoils,a key process in which we have chosen component integrity over production speed

• Ourproprietarycoildesign/process, which we have developed in-house, is carefully optimised to give maximum strength and longevity.Nocompromisehaseverbeen considered just to deliver short-term gain

• Closetolerancewiresaresourcedfor minimum unit to unit variation

Suspensions• Polycottonmaterialformaximum

strength and longevity

• Materialpropertiesselectedforoptimum strength, adhesion and longevity

TerminalsAll models use metal push terminals as standard to ensure a perfect termination without the requirement of soldering.

Dust CapsAll models use a solid composition centre dome and work as an extension of the cone, giving a greater cone area.

• Madefromlongfibrepulpandon processes optimised for sound quality and never for speed of production

AssemblyAt 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.

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.

The ultimate 15” transducer choice for no compromise bass reflex applications in which the light weight benefits of neodymium offer substantial advantages over a conventional ceramic magnet assembly.

A smooth extended mid range to allow easy crossover integration makes this a perfect transducer for applications including studio monitors and high quality AV.

The impressive Xmax ensures that control is maintained at low frequencies. Use of neodymium technology ensures that this is achieved in an extremely lightweight design.
