Thanks randyraven.. I shall have a peek at the Bose ones.
Cado - I did ask a Q recently about getting rid of some of my other *antique* hi-fi separates (amp, deck etc) and one kind AB user mentioned Freecycle - I advertised them on there and they were snapped up that evening (they were still working) but at that time I hadn't realised just how bad my speakers were. I only discovered the cone problem this evening. Don't worry, you're not cracking up - it's just that I am now asking about my speakers, not the rest of the gear !
