Hi Henry,
I would like to underline a couple of things,
1-
for some reason I believe tangential arms are more sensitive to res-freq than pivot arms, perhaps because the cantilever also has to support the burden of the lateral mass ?? I'm not sure. As I noted elsewere it was an amazing improvement in sound quality when I rised the res-freq from about 5Hz to 9,5Hz, in my old T3F.
2-
I do agree with those than think the cantilever will overflex with too low res-freq.
3-
Finally, what about speakers ? I personally cannot listen to to closed-box speakers. I prefer panels or OB desings like Siegfried Linkwitz & John Kreskovsky.
Electronicaly EQ-subs are not possible to be used when res freq goes under 6Hz, even if LP is perfect as the mere touch of the stylus in the first 5mm will send the woofers to bottoming ... but not only. When I had the Apogee Full Range the woofer-panel went into crazy/over excursion even if the Krell Elec-XO did not used any EQ. OTOH when you stick to the righ res-freq. nothing bad happens.
Regards,
