Sometimes you get a surprise, and sometimes, even when it’s bad, it works out. A couple of years ago I bought some used JBL subs. We had been renting them for Rocket 8 gigs, once a month for several months, so at some point I decided it would make more sense to just buy them outright from the owner. Problem was, we were not the only ones renting them. When I took delivery, it didn’t take long to realize one driver had gotten blown since we last used them. My friend owns a pro-sound consulting and install firm, and he hooked me up with an original JBL recone kit for a very nice price – free, as it had sustained minor damage in transit, Nothing critical, but it could not be sold as “new”. Of course I accepted the terms. Here’s what happened next, in fast-forward motion. The key to a good re-cone is to get the coil centered perfectly and make sure everything is nailed down and consistent. Use a current-regulated variable power supply to check for rubs as you go. Oh, and take your time, be patient and work with an eye for detail.
