Rogers LS3/5a Repair

Who repairs these speakers? One of my "low" frequency drivers has begun to buzz.
Richard So in Phoenix, (602) 431-3188. Superb work. Ship the driver to him if he agrees to repair it for you.
I know this sounds a bit lame, but have you turned the driver upside down in the cabinet? If it has just loosened up a little around the spider and the voice coil is touching the magnet, this may be all you need to do.
