any suggestion of (single-driver) speakers that can play both chamber and orchestra music wellTall order for a full orchestra. Either look at spkrs like the Yorkminster or Canterbury (Tannoy) /Pi speakers OR compromise on the full Mahlerian orch & consider Cain&Cain, Zu, etc.
Go for s/thing that's over 95db spl nominal sensitivity so you can reach ~110db spl with yr amp before clipping.
BTW, these spkrs sound marvellous
