The stock (PAS?) speaker in my Basic Black has some voice coil rub. I'm leaning towards getting a new speaker, getting a proper recone seems like a bit too much trouble. The cabinet is rear ported (about a 5" circle port), the cabinet volume is appx. 2.8cf (18" high, 20.5" wide & 13" deep). The stock speakers measures 4.0 ohms on my multimeter, which in my experience is more consistent with an '8ohm' speaker. From looking at the Eminence site and specs, it looks like the Legend CB158 is the most obvious choice, and most places seem to sell them for $117-$129 shipped which doesn't seem bad at all. Any other speakers I should consider? Maybe the Eminece Beta15A? -thanks!
