I have Def Tech Powerfield 10" Subwoofer that works great. I couldn't find the impedance online and the manual I found for it online, doesn't list it. So I took it out of the enclosure and measured it with a multimeter & it reads 110. Am I missing something here? Isnt't supposed to be 2, 4, 6 or 8 ohms?? Why the crazy reading\n\nI found an old listing from years ago, of the same Subwoofer, but the 8" version listed online as part of a HT in a box. The speakers in that set are the Procinema 60's & have a 4 ohm impedance listing, the Sub again has no impedance listed.\nProCinema HT\n\nAnyone have the same sub or know why as to the impedance reading?
