drivers for a 2 way that sound as a sonus faber concertino

hi, i have a sonus faber grand piano that i've benn using since 2005, it sounds great, but they are now a bit damaged by the time, i listened to some sonus faber concertino, i liked the sound, since i love making my speakers since i started at 20, i tought that i could do it "more professionally" but on parts express and audioimports there were to many speakers to choose from, so i'd like to hear you're opinion, i like warm sounds and deep bass, i listen to jazz, can you help me find somthing good for some 2 way speaker under 600$ (only drivers)
