Thiel Owners

I recently spoke with Rob G. about the same issue re my 3.7s. He said that the grill cloth is an integral part of the speaker design in all models except the 3.7, where it is entirely cosmetic.

I always believed that too.  I haven’t discerned any downside so far but I’ll listen to them this way for a while and then put the cloths back on. 

Tony - what model do you have?

CS6.  I bought them as demos from a dealer in 2005.  They are beautiful speakers in a light oak finish. 

   Would my and unsounds observations of a more relaxed sound from fully coherent box and cone speakers also apply to full-range panel speakers like Martin Logan CLS, Quad ESL? 
   And for that matter all the single driver cone and box speakers like Zu, Dayton, Tannoy, and many small companies making simple efficient speakers for the SET market?
   There must be a reason I've been a headphone junkie since forever...
