Dayton Audio DCS165-4 6-1/2″ Classic Subwoofer 4Ohm

Dayton Audio DCS165-4 6-1/2″ Classic Subwoofer 4Ohm Overview:Dayton Audio’s rugged DCS165-4 6-1/2″ subwoofer has all of the performance-enhancing attributes you would expect from a larger high-output subwoofer. With a vented pole piece and 4 ohm, 4-layer voice coil, this driver can handle up 100 watt RMS. The non-pressed paper cone is reinforced with Kevlar to increase stiffness, which promotes linear travel through the limits of its excursion. In addition, the pole piece includes a copper cap that keeps inductance to a minimum. The DCS165-4 driver is ideal for use in small multimedia speakers, portable speakers, or even automotive systems where space is at a minimum. Product Highlights:4-layer VC with polyimide former allows high power handlingVented pole piece and bumped back plate provide plenty of VC travel with minimal compressionCopper pole piece cap minimizes inductanceRigid non-pressed treated paper/Kevlar cone with rubber surroundGreat for home and automotive applications Product Specifications:Speaker TypeSubwooferPower Handling (RMS)100 wattsPower Handling (max)200 wattsImpedance4 ohmsSensitivity87.4 dB 2.83V/1mFrequency Response36 – 1,100 HzVoice Coil Diameter1.51″Weight                                                                                                                                                                                  4.8500 lbs. Thiele-Small Parameters:DC Resistance (Re)3.4 ohmsVoice Coil Inductance (Le)1.43 mHResonant Frequency (Fs)35.7 HzMechanical Q (Qms)6.62Electromagnetic Q (Qes)0.36Total Q (Qts)0.34Diaphragm Mass Inc.
