This driver suffered a magnet shift. It was in a set of Polk RT5s shipped to me without proper packing. I bought a nice replacement driver for the RT5 and set this driver aside. Later, I got ambitious and decided to repair it. The repair turned out reasonably well, but I don’t have a need for it.
I don’t want to oversell this driver. It appears to have been worked on before. You can see the residue from that work on the cone. That work seems fine but I’m not sure why it was undertaken. At any rate, after the repair I installed it in the RT5 cabinet and listened to it for a few days and I can’t tell that it sounds any different from the others.
I paid 60 bucks and shipping for the replacement driver mentioned above. I’m thinking perhaps half that for this one given its history. Mostly, I like to see it go to a good home. As you can see, it’s good enough for the garage speakers but otherwise I’d probably leave the grill.
Check the photos carefully. The adhesive you see is the prior work. I removed the dust cap but I did not separate the cone from the surrounds. The excess epoxy you see around the magnet is intentional as it’s there to help lessen the chance of another magnet shift. In my book that’s considered a good idea on any Polk driver. I used Arleene’s tacky glue for the dust cap and to attach the surround to the basket. Devcon epoxy to reattach the magnet.
