Thiel Owners

jafant , Tom and all 

Thank you , I don't know about the grill on the 2.4 but on 2.7 there is a metal dome over the coaxial speaker and I suspect that this has a lot to do with slight reduction in the mid and treble .  When I left the grills off I heard more definition in voices (like breathing or multiple voices ), I felt that I heard inside a acoustic guitar , listening to a full orchestra it sounded more alive . 

I know this sounds like a lot but as I confessed to prof I'm not very good at describing what I hear .  All I know is that listening now is just a little more work taking the grills on and off but nowhere near the work it takes listening to vinyl  in trying to get every last bit of detail .

I left the grills off my first speakers BIC Venturi 6 and my second set of speakers Image Concept 200 .  When I got the Thiels I started leaving them off but at that time before equipment changes, upgrading and room treatment installation they sounded bright to me , until Tom mentioned it I have been leaving the grills on so once again I have to say Thank You Tom .

Thank You for another Thiel Audio history lesson. Such wonderful information on Jim's design and thoughts for Grill implementation.

Happy Listening!

The CS 2.4 / 2.4SE has a recess section built into the baffle for Grill to fit flush.

Magnets hold the Grill in place perfectly. Your aural descriptors are fine. I will add that One does not have to work to enjoy presentation and sound from Speakers.

Happy Listening!

Rob - the magnets are installed into blank-bottom holes drilled from the back of the baffle. I don't know how many are in the CS2.4. In the SCS4 there are 8. Two pairs about an inch from the top and bottom corners plus another 4 flanking the coax driver. The fields are strong enough to need a tool to remove the perforated steel grille. I'm not a fan due primarily to theoretical considerations of interacting magnetic fields with an electrically conductive aluminum baffle between them. My objection notwithstanding, I'm confident that Jim vetted the implementation and did not object to it. The magnets are probably far enough away to not do any real damage.

However I would rather have a mechanical solution and lose the hypothetical downgrade mechanism.

Thanks Tom

After looking at images of different Thiel speakers I'm guessing that most just have speaker fabric covering them , since the 2.7 and 3.7 have the same design coaxial speaker that are not recessed that they might be the only speakers with a metal honey cone dome covering them for protection .
