Shashi,
I do not believe it is self contradicting. There IS am implication that using multiple drivers allow more SPL over the the entire driver range, but the issue is the driver headroom now allows you to lower the crossover frequency without risk of overdriving the tweeters.

I think my point is not made clearly.
The point I am making is from the Paul McGown example of lowering the crossover point of tweeter from 4K to 2K by aggregating multiple tweeters. In such a case, is it not reasonable to assume the Fs of the tweeter is somewhere around 3K? So, the sensitivity at about 2K would be about -10dB below the tweeter sensitivity. If the 2K frequency is raised by 10dB, the normal sensitivity of the aggregated tweeters (in acoustic domain) would also raise by 10dB. That's not a good thing even if ignore the distortions the tweeter generated by running at frequencies outside is designed range.
Tom,
Ofcourse, Fs of 500Hz and Crossover at 2500Hz is not an issue.
I am considering something like Fs of 2000Hz and Crossover of 2500Hz.
