George & prof - I think the low-pass 3dB down point should be @ 45Hz, the natural 3dB down point for the 2.7. There is no high pass / low cut filter in the XO, so the sub crosses to the woofer at the natural bottom rollin of the woofer.

Hope you enjoyed the holiday weekend in full. How are developments going in your Hot Rod garage?  Happy Listening!

J.A - Thanks for asking. Good progress re comparative listening and measuring tools. Great appreciation for Jim's component choices within his budgets. I'm presently testing various mechanical upgrades: cabinet stiffening, stiffer driver mountings, XO panel isolation, etc. Advantages of hindsight include location of cabinet resonances via reviewers and more sophisticated instrumentation. I can address some of them, others are baked in. Many electronic components are chosen, but no crossovers yet. pm to you.

Thanks for that info re 2.7 and subwoofers.  I've saved it!
Cheers!
