WillistonAudioLabs Posted February 20, 2012 Report Share Posted February 20, 2012 Most of you old schooler's will probably remember this.... 1992'ish Polk Audio C4 Subwoofer: Original MSRP was around $500. Not exactly a bass head's dream sub, but nice, clean hard hitting bass in a very small enclosure. I just picked this up off CL and it is in near MINT shape. Very cool design. Specs: Driver complement - Four 6x9 drivers monted in a isobaric push pull configuration Enclosure type - 4th order bandpass Frequency response - 25 to 150 Hertz Sensitivity - 94 db @ 1 Watt @ 1 Meter Recommended amplification - 25 to 200 Watts per channel Impedance - 4 Ohm stereo, 2 or 8 Ohm mono Dimensions - 8" H x 26.25" W x 17.125 D Weight - 26 pounds Pictures: Video: Quote See my videos on YouTube http://www.willistonaudio.com Many tests and demos of OLD and NEW SCHOOL car audio gear!
