There are many ways to approach building transducers, but Precision Devices follows just one: an unremitting desire for excellence.
Their quest for excellence ensures that all Precision Devices' transducers are imbued with quality from the first computer simulations by the Research and Development team to the final product off the production line.
Precision Devices transducers are individually hand-built in England to 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. From some of the world's most powerful bass units to the most intricate high-frequency devices, each Precision Devices transducer is carefully crafted to give the highest levels of reliability, performance and tonal distinction.
With roots firmly in the touring sector, it is not surprising that PD is 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.
The world wide reputation for high quality performance, reliability and ruggedness is no accident - it is the result of a no-compromise approach to delivering quality, commitment to providing world class customer service and an unceasing quest to ensure that the products are at the forefront of engineering development in the audio industry. They are dedicated to providing clients with complete product satisfaction and are proud to have their products used by many of the world's premier loudspeaker companies
What makes a Precision Devices transducer special?
THE PRODUCTS
All loudspeakers and compression drivers are designed using the finest materials, with no compromise on cost. They are all made in the PD factory in the South West of England by craftsmen who take the utmost pride in producing a perfect product.
CHASSIS
The unique twelve-sided chassis are manufactured using die cast aluminium alloy with added sectional strength, often twice as thick as that of most other 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 means that should the cabinet be dropped there is far less chance of splitting between the holes and the bafflle.
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
CONES
The cones, also made in England, are carefully inspected prior to use to ensure they are within fine set tolerances. This ensures that a consistent sound quality will be found throughout the series.
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
-
The 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
The voice coil is the heart of the speaker. We produce 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 great strength and to maximise its energy transmission abilities.
-
Laminated construction for maximum strength
-
Wet wind process used on all coils, a key process in which component integrity has been chosen over production speed
-
The proprietary coil design/process, 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
SUSPENSIONS
-
Poly cotton material for maximum strength and longevity
-
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 requiring soldering.
DUST CAPS
All models use a solid composition centre dome and work as an extension of the cone, giving a greater cone area.
ASSEMBLY
At the end of this chain is the vital step which guarantees that all the effort 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.
-
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 a custom built facility which was designed by the team from a blank canvas to optimise all aspects of production
