Yes, I know that...

Yes, I know that the usual 2.5-way uses identical woofer-mid and woofer drivers; the difference is the inductor on the low woofer.

But (even though it was about 25 years ago) I think I remember that because they were making their own 7-inch drivers, Wilson Benesch had the luxury of being able to specify different compliances for the upper and lower 7-inch drivers surrounds. IIRC.

One thing I forgot to mention was that in the 2.5/TMM DIY kit I recommended, another function of the lower woofer is to raise the efficiency or sensitivity of the woofer function as a whole which means that the very efficient ribbon tweeter has to be padded down less radically in the crossover.

IIRC, the Fountek NeoCD3.0 ribbon tweeter is 93dB sensitive, and it is very hard to find a conventional woofer that is that sensitive.

atb,
