Thiel Owners

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!

Tom and Prof

George - thank you for this post. I used the 2.4 spec in error. The germane point is that Thiel's Passive xo does not attenuate the main speaker's low end - in this case a little below 35 Hz.

When I first saw those specs, I noticed the Impedance of 2.4 ohms @ 160 Hz. Thankfully, the 4BSST2 was up to the task.
