Thiel Owners

Beetle - I'm not sure how much of that is correct - coming from different sources over time. I said mechanical crossover, but was enlightened to the contrary. Also the carbon diaphragm idea was countered by machined aluminum / beryllium alloy. And the sealed bass might have been my speculation based on my knowledge of Jim's fundamental bias. I never spoke with him about it, and my input comes from three sources with their own reads on the prospects. Even though his illness was kept secret from all of us, he knew he was dying; so the 7.3 may have been mostly speculative. But it seems it was what he was working on at the end.

Sorry for the confusing post. Other than the mechanical crossover, the rest of my post was intended as fantasy. And now you clarified that the crossover bit is also imagination.

Happy Thanksgiving 

Sorry I missed your humor. Let's call it a CS4.

Have you ever considered writing a book about
Jim and the Thiel speaker company ?

I owned a pair of CS7's several years ago. The dynamic "slam" I got from them in some pieces of music was absolutely amazing. An upgrade from Thiel at the time was supposed to improve the high end but it never happened, IMHO. I sold them because they sounded too bright for me, even with good tube amps.
