>About the tweeters, I already verified this with my dealer before I bought the 1NT: the CDM NT series does not use *exactly* the same tweeter as the N800 series.I've been trying to figure this out ever since the CDM series came out. When I asked my dealer, he told me the tweeters were "identical". However, I never take what a dealer says at face value anyway, and this discrepancy between different dealers is just another example of why.
I'm going to write B&W and get the real scoop.
My guess is the tweeters are very similar. Since the rear of the tweeter is hidden in the CDM series, B&W may have taken steps to skimp on the rear portion of the assembly, perhaps using a shorter tube.
The tweeters within the Nautilus 800 series are "identical" for the most part, with a few cosmetic differences. The tweeters on the Nautilus surround speakers are "identical" to the N805 speakers, but with a shorter tube. The N802 tweeters use a slightly longer tube than the N805 tweeters and are encased in a more glossy and durable mylar material. The drivers are essentially identical, however.
This is what I meant when I said the CDM speakers use the "same" tweeters (I did not say they were identical or interchangeable). One person a while back wrote that the CDM 1NT tweeters were indeed "the exact same tweeters used in the N805", but I would not go about spreading this bit of info without first checking with B&W.
Ultimately, different crossover designs will make the same driver sound different. But I still can't see how the CDM tweeters can deviate so abornormally in sound from Nautilus speakers. Like I mentioned in my earlier post, I haven't detected the alleged "abnormal peak" on the CDM series.
