I have a pair of Rti a7's.One of them has a bad driver-it's not bad but it sometimes crackles at higher volumes.I think I know what driver it is but I really can't tell without swapping the suspected bad with one I know is ok.The drivers look like they take allen wrenches in the front.I have sets of both metric and english and nothing fit.Today (while at work)Polk support emailed me that it needs a 3mm hex so I ran down to the hardware store ,got home and still no luck.What am I missing here?I can't seem to find a service manual anywhere on the net.I just hope this isn't one of those "doh" moments coming up.

    It's 9/64, standard for Polk these days. Not sure why someone told you 3mm.

    IIRC my A7's used a Torx (star) screw on the drivers.
