Main difference is in the tweeter as pointed out by Audimiata. The CDM 1NT's tweeter carried down from the Nautilus line is more refined and open so I would say the 1NT is overall a better speaker.
B&W CDM 1 SE or CDM 1 NT
Can any one tell me the differences between these 2 speaker: The B&W CDM 1 SE and the CDM 1 NT. Which would be better with the Mcintosh 4100 Reciever for mainly classical music.
