Thiel Owners

How wide is the slot and how deep from the inside / back to the start of the flare? Is the inside edge eased / rounded in any way?

For the visually inclined among you I have posted some photos on the diy audio forum.

I found an image of a supposedly CS6 xover for the midrange. Based on the image, it seems the xover employs an all-pass filter for the midrange.

My CS2.4 serial number 384X, the last digit faded out unreadable, this is xover photo taken 5 years ago before modding.

When I completed building the xover boards, I let it run for 24 hours with a dummy load for the components to settle then hook it up to the speaker drivers. At first, it sounded like a AM pocket radio, after a few hours play time, sound quality keep improving until about 100 hours then the SQ become stable and the sound open up with a holographic sound stage... YMMV!

I think that makes sense. The Thiel sensitivity is about 6dB higher than the Kef (90.7dB vs 84.5dB according to Stereophile’s meansurement).
