I get a woody just looking at that quarter-sawn oak thru-tenon frame.

If I remember Mr. Larson from metal shop correctly then "chubby" is the right term.

Congratulations!

With these big panels, I'm sure you can do a lot lower than 70hz.

You are right, they do go lower than 70 Hz, but I have my subwoofer (4-18" woofers in an infinite baffle) set for 70Hz. I may play with that crossover point though.

Many important considerations in the choice of the crossover point. Claiming several decades of experience, here are some.

1. With a steep crossover and a pretty clean system downstream of the crossover, no directionality confusions with music even as high as 140 Hz... when tested blind*.

2. Somewhere around 80 Hz and below your sources start demanding substantial power. So you want to keep sounds needing power in the subs so your ESL system isn't challenged too much. Don't try pushing the ESLs into a range where cone drivers are OK. (The old Janzen speakers with a 1000 Hz crossover were quite ESL in their sound quality.)

Ben
*when tested with subs visible, people will swear they can "hear" directionality of music influenced down to 5 Hz.
