Dayton Audio PC83-4 3″ Full-Range Poly Cone Driver

Dayton Audio PC83-4 3″ Full-Range Poly Cone Driver Overview :The Dayton Audio PC83-4 3″ full-range driver features a poly damped woven glass fiber cone, damped rubber surround, and high energy motor. The addition of a copper cap on the extended pole improves cone control, lowers inductance, and decreases distortion allowing for improved high frequency response. Offering great full-range performance, controlled off-axis response, and high efficiency, this driver will provide impressive output for its size. Perfect for use in line arrays, sound bars, portable speakers, or even car audio systems, the Dayton Audio PC83-4 will deliver high fidelity and low distortion from compact applications for an amazing value. Product Highlights :Copper cap to keep inductance under control and extend high frequency responsePoly damped woven glass fiber cone controls cone break-up and provides a smooth roll-offSmooth response with true full-range reproduction for simple speaker designsHigh energy ferrite magnet increases BL for higher efficiency and more outputGreat for MTM bookshelves, car audio, or line arrays Product Details:BrandDayton AudioModelPC83-4Unit of MeasureEachWeight1.15 Product Specifications:Nominal Diameter3″Bolt Circle Diameter3.64Power Handling (RMS)30 WattsPower Handling (MAX)60 WattsImpedance4ΩFrequency Response80 to 20,000HzSensitivity86.8dB 2.83V/1mVoice Coil Diameter1″ Thiele-Small Parameters:Resonant Frequency (Fs)78.7HzDC Resistance (Re)3.9ΩVoice Coil Inductance (Le)0.38mHMechanical Q (Qms)3.41Electromagnetic Q (Qes)0.64Total Q (Qts)0.54Compliance Equivalent Volume (Vas)0.07ft³Mechanical Compliance of Suspension (Cms)1.47mm/NBL Product (BL)2.9T·mDiaphragm Mass Inc.
