My ancient speakers, bought as replacements to very ancient 'separates', sounded like a pigeon was making a bolt for freedom from the cabinet. On investigation I found the cone of one them had gone to HiFi heaven (pic shows rear of it for reference). Although they were bought at the time of the great flood as Goodmans the speakers are Jamo (Danish?) and are 8" diam. Not that I'm tight, honest, but prefer to preserve rather than jettison at the first sign of bother. Anyone know where I can get a replacement for this bit? It's coupled to a DENON PMA255 amp, a JVCXL-V120 cd player, and a Denon deck. Any info would be greatly appreciated because Pink Floyd on only one speaker just doesn't cut it when you want to play along with Mr. Gilmour and give it some welly.
