CNO-T25 Based on response from the CNO construction, a few people think the T29 tweeter prices are a bit steep - and they are indeed, thus this T25C003 version. The obvious question is: How much better are the T29 versions? Hmm....that is a tough one. I do think the T29s are better, but if I had to pick either in a blind test, I'd probably be in trouble. If I had to point out some difference, it might be that the T29s are better handling large sound volumes, i.e. they can play louder before compression. At moderate listening levels, the differences are more subtle. I won't do a lot of writing on this one. For more comments on drivers and construction, please read CNO mkII article.
Crossover
The crossover in many ways resemble the CNO, being a series construction - and including some modest equalisation to the midband. This caused some controversy with the CNO and I strongly dissagree the equalisation "kills the sound". It is very easy to fool the ear (our brain) by rising a specific frequency band that will spew out details - if the musical source allows - but basically it's low-fi and not how the reproduction was meant to be.
