HIGHPERFORMANCETHROUGHPRECISIONENGINEERING

Founded in1987,England.PrecisionDevicesisregardedglobally asaleadingmanufactureranddesignerofhigh-end loudspeaker transducers.Forover25yearswehavebeendrivenbyapassionand philosophy to create next generation drive units capable of achieving superior levelsofacoustic performancecombinedwithexceptional levelsofstrengthandreliability.Builttobedriventotheirrated specificationandoftenbeyond,Precision Devicestransducersare synonymouswith uncompromising qualityand enviable performance, instantlyrecognizableand highlydesired.Widely recognisedasthe worlds'finest,mostprestigious loudspeakers.

PRECISIONDEVICESINTERNATIONALLINE

Two origins,onevision,bothof very high-end quality.ThePrecision Devices International line isonlyavailable in China;notthe rest of theworld.Providinga unique opportunitywith 100 % focus on the China market.

The PDl product line featuresall new designs specifically for the China market coveringbass,midrangeand high frequency-devicesapplications;nothingcopies orduplicatesthe‘Madein England'product line.The twodistinct lines-UKand China-work in synergy with each other,whilst having different character they remaintrue tothePrecisionDevicesdesignDNAofquality,performanceand precisioncraftsmanship.

It's not just our end products that are world-class:our production processesare too.Over the yearswe've made manychanges to ourmanufacturing practices, all of which were implemented to ensure our standardsare nothing short of outstanding.We employ a modular construction processwhereby each and every keystageofconstruction is testedand signed off individually.The result isa thoroughlyaccurateand natural sound,alongwith improved reliabilitythrough precisely designed and manufactured components.These standards,among others,have helped usbuild strong,lasting relationshipswithour supply chain partnersand customers.

HIGHFREQUENCYDEVICESOVERVIEW

INTERPRETINGOURDATA

POWERRATINGS

We measure all of our drivers according to the A.E.S.standard protocols.Each driver is tested for 2 hoursat rated power over the drivers working bandwidth,after which the driver should show no appreciable signs of damage.Mechanical properties are also taken into consideration when classifying power rating even though the electrical properties of the voice coil can often exceed the drivers' isted power rating.

THIELESMALLPARAMETERS

Fs Resonance frequency of the driver's moving mass (in free air).
Re DC resistance of the voice coil, measured in ohms.
Qms Mechanical Q of the driver at Fs.
Qes Electrical Qof the driverat Fs.
Qts Total Q of the driver at Fs.
Le Voice coil inductance measured in millihenries.
L2 Para inductance measured in millihenries.
R2 Eddy current resistance measured in ohms.
Vas Volume of air equal to the compliance of the driver's suspension.
Mms Movingmass of the diaphragm includingair load.
Sd Effective surfacearea of the diaphragm.
Cms Compliance of the driver'ssuspension,in metres per Newton (the reciprocal of the units stiffness).
BL The product of magnetic field strength in the voice coil gap (Motor unit strength).
Xmax Maximum linearpeak excursion of voicecoil travel.
Vd Volume displaced by the driver'scone.
