ipod and its plugin amplifier, i can now hear a huge difference with
the records/cds he also left. he has used for years a pr of monitor
audio 352s and one of them has recently developed a rasping sound,

suspension sag
over the years has let the voice coil start scraping the magnet.
Though if the woofer has a PVC surround, it is probably hopelessly
