My first PF115 had very bad voice coil rub and so I sent it back. The two cabs I have since that one are just fine with no issues. I ported one of them to give it a little more low end, and I added side handles and side mounted speakon jacks as a nod to the old B15's. The handles make it easier to lift the top cab when running a stack configuration, and the side jacks do bypass the internal crossover built into the stock jackplate - but my intention of having the side jacks was really just cosmetic.
