hi all. recently asked for help to change and upgrade my speakers. seems i need to keep these speakers as system unusually configured. occurred to me i could have the tweeters replaced, maybe midranges too, when i get system serviced in the near future, possibly at hy-tek in dalston london, unless anyone has any other suggestions. any thoughts on a tweeter that might be softer and less harsh at top end when really pumping the volume that might do the trick so worth me looking in to? thanks v much.
