redpackman Posted November 21, 2020 Report Share Posted November 21, 2020 Pulled this from an old EPI M250. The ohm meter says it's 4 ohms. All the other speakers in the M250 speakers are 7 to 8 ohms. Here's a photo of the identification number on it. Is this an EPI manufacturer or an addition later. It has a square magnet just like all the others but there are other differences (dust cap diameter etc.). Quote Link to comment Share on other sites More sharing options...
MrPajamas Posted December 2, 2020 Report Share Posted December 2, 2020 Hello red packman, My guess is that the woofer was reconed. and used a voice coil that was close to original but not the same impedance The basket frame and magnet assembly is original. Need a picture of the cone and front of driver to tell more. If you post photo I can tell you more. Hope this helps. MrPajamas Quote Link to comment Share on other sites More sharing options...
