Dayton Audio PS220-8 8″ Point Source Full-Range Neo Driver

Dayton Audio PS220-8 8″ Point Source Full-Range Neo Driver Quick Overview:The Dayton Audio PS Series drivers do it all: true bass, articulate midrange, and balanced, extended highs. An intensive program of design and testing has yielded full-range speakers that feature high sensitivity and smooth response, both on- and off-axis. Although an ideal match for lower powered Class A and Class T designs, the PS220-8 8″ driver’s superb resolution and natural sound quality make it a viable option for an even wider variety of applications. The PS Series’ audio performance is complemented by the speaker’s striking appearance—they look great in dipole and other open back designs, too! Product Highlights:High sensitivity/minimal distortion—an ideal match for lower powered amplifiersParasitic HF cone and carefully engineered phase plug extend on- and off-axis responseSolid bass performance, thanks to usefully high excursion capability (5 mm Xmax)Optimized neodymium magnet provides high motor strengthLow-mass copper clad aluminum voice coilCopper cap and copper ring on pole piece reduce inductance and distortionKevlar reinforced paper cone is lightweight yet rigid and well controlled Product Specifications:Nominal Diameter8″Voice Coil Diameter1″Power Handling (RMS) 40 WattsPower Handling (MAX) 80 WattsImpedance8ΩFrequency Response40 to 25,000 HzSensitivity96.5 dB 2.83V/1m Thiele-Small Parameters:Resonant Frequency (Fs)56.5HzDC Resistance (Re)6.2ΩVoice Coil Inductance (Le)0.73mHMechanical Q (Qms)5.73Electromagnetic Q (Qes)0.40Total Q (Qts)0.38Compliance Equivalent Volume (Vas)3.19ft³Mechanical Compliance of Suspension (Cms)1.41mm/NBL Product (BL)6.15 TmDiaphragm Mass Inc.
