I bought a pair of second hand RF3 bookshelf speakers. However I discover that their cross-over has some problem making them sounds different from each other. And when I check them further I discover that the crossover is not original. After testing, the speakers units are normal. Can anyone provide the circuit for its cross-over and the figures of the components? Besides do anyone know the 'dividing point' for the Hi & Low frequencies? Please kindly send the reply to the below mail: andra886@yahoo.com.hk
