Thiel Owners

Some important news was found out from my DRC measurement steps (first step actually).

I want to clarify a point about the slight harshness I was hearing on the CS3.7 top end. I was saying it was not as smooth as the KEF LS50.

The measurements showed that right speakers Coax driver is out of phase with the left speaker Coax (maybe one can say the opposite). There is some harshness on the frequency response due to this miss-wiring. I guess my hearing is good.

Prior to the sale I knew that the previous owner got a new Coax driver from Rob G and soldered the Coax wiring himself. He was a little worried about the wiring since there was a 2 week delay with shipping the driver to Rob and getting the new one. Anyways, the previous owner and I are working to get this fixed, should be an easy job. I will give Rob a call tomorrow to find out the specifics of the job.

So the DRC work is halted until this out of phase issue is resolved. I am going to find some electronics guy/gal to do the solder, since I am a newbie on that and I want it perfect.

BTW - the engineer up in Canada, Mitch Barnett, used to owned Thiel CS3.7 and he loved them.

@jafant My pressing of the SACD is from SME records. I now have my SACD player less than a foot from my seating position. Makes things easy. Getting real lazy with age.

SME is the 1st pressing (1999) 

Happy Listening!

I called Rob Gillum about the COAX installation know what needs to be done to resolve the out-of-phase issue. I have decided to use the services of a local audio store in Santa Barbara. They will send a repair tech to my home next Tuesday to do the soldering. Learning a lot of technical stuff with this hiccup.

I decided to move the Thiel CS3.7 to a new position. I now have them 2 feet from the front wall and about 2 feet from the side wall. The speakers are now closer together about 6 feet apart. The sound now is better than any other prior placement. Even with DRC I will keep this positioning, mainly because I have 3 out of 4 sources that will not use DRC. Only my digital streaming via ROON will use DRC (if I like it).

So next week is when the interesting stuff happens. Enjoying the out-of-phase tunes until then.

I also bought an CS3.7 Outrigger for the speaker feet. My 4 year old first words when he saw the CS3.7 in my office was "I want to climb it".

Nice catch or should I say good ears ,
but strange because the coax speakers polarity are clearly marked
with the red and black wires going from the solder pad to the speaker ,
and  if the crossover is like the 2.7 the negative / black wires from the tweeter and midrange  are soldered together .

I hope that wrong wiring is your problem .
Good luck and hope it's not to big of a repair bill .
