[quote]...drivers are forced to operate right up to the edge of their working ranges in order to meet the tweeter in a moderate-distortion frequency range.
If you lower the crossover frequency, tweeter IM distortion skyrockets , resulting in raspy, distorted high frequencies at mid-to-high listening levels;
[unquote]
You criticising a trade off between woofer cone breakup and high distortion in the treble region, your naive suggestion will result in the woofer meeting the tweeter in high distortion zone, the trade off being 'high distortion' in the treble region described in the paper as 'raspy, distorted high frequencies at mid-to-high listening'. Back to today, looking at the the new 705 speaker, the woofer breakup mode is no longer in the 3-5 Khz region, so the behaviour Lynn decribes is really only applicable to a particular implementation of kevlar.
The truth is what is true, not what you believe.
