Vintage Cerwin Vega 101W2 woofer, from the Cerwin-Vega D-2 and  Cerwin-Vega D-3 model lineup. This woofer is freshly reconed and the impedance is where it should be a 4 ohm. My meter is off by .1 ohms so its really 4.3 ohm which is acceptable and normal for a 4 ohm speaker. Item will be shipped safely. Dustcap and surround were replaced. Tested and working. This 10" woofer would probably work in other models as Cerwin-Vega woofers were very similar but this model is from the D ( digital) series. Any questions please ask. Thanks for looking.
