Thiel Owners

Tomthiel, 

Your baffle modifications sound very interesting. I'm excited to see exactly what will be implemented and what the sonic effects will be. I'm planning to keep my CS2.2 speakers and willing to invest in effective tweaks/updates that make a great speaker even greater.

While waiting for my braised brisket to cook, I went to the "Speakers" topic and went to the beginning, hoping to find threads about AR3a speakers.    Found this:    Not much has changed.

Thiel 30 April 2000 thread:

"Looking for advice in driving Thiel 2.2s. I love the clean, detailed sound they provide with $10,000 amps, but my current gear (mass-market junk) doesn't cut it. Advice? I need both an amp and a preamp, and am willing to spend up to about $3500 total."

Vibrations from Both speakers at low hz , could it be the wires ?

I have a CD called Irrational, But Efficacious!  by Ayre and Cardas .
I play this as break-in sound every time I've installed new components  on my amp project. The CD has a track called full glide tone 
that sweeps from 5hz to 20,000hz , my CS2.7s do not start to 
produce sound until 1min. 4secs ( 30hz ? ) .
In the past I played this disc at listening level but the other day 
I had replaced all the power capacitors so I thought that I'd
try a louder setting.  
Both speakers had this vibrating noise that sounded like a metal plate 
or my thoughts speaker wires touching the bass basket .
There wasn't any distortion to the sound , just this added vibration noise 
that would go away as the frequency increased during the sweep .

Have any of you experienced this ?
Do any of you have any ideas about what it could be ?

I plan on e-mailing Rob for information about getting to the crossover
boards ( something that I've been working up the courage to do ) . 

I'd like to thank holco for his beautiful system images that help me visualize the Xover boards .

With both speakers it could be a room mode or other boundary effect. Test it by changing locations in the room.
