Thiel Owners

Wow Thanks beetlemania

None yet , that project will begin right after New Year .
Still working on the amp , 32 caps and 3 resistors 
with 2 resistors and 4 recitifiers going in next week end 
leaving just 10 more caps and 8 resistors to go .
I doing this in small groups to see how they affect the sound 
and control any problems .
I've been using Hovland and Nichicon caps 
but for the speakers I think I'll use Jupitor CU caps .

I’m still confused as to what you did when you experienced the resonance.

Ayre recommends playing the IBE at “moderate” levels which I interpret as less than typical SPL for music.

When I did my XO rebuild, I searched for cabinet modes with steady tones (ie, not IBE). At higher SPLs, there were many frequencies that caused distressing distortions. I never determined the cause - amp or speaker - but immediately stopped that exploration!

Thank G*d, actual music sounds sublime!

Jupiter copper is supposed to sound superb. i considered those as bypasses. Of course, you can’t do the whole board with those even if you have unlimited budget (and space). Jupiter Cu capacitance is nowhere near the values on a Thiel XO.

As a general observation, wire management is a big deal. Thiel buried long runs in channels routed into cabinet walls, sometimes used goo to attach to braces and generally made a spiral by rotating the driver as it goes into position. If you've had drivers out, you may have wire rattle.

Thank you Tom

I haven't taken the speakers out yet , not until I start the crossovers upgrad project .

To answer beetemania's question and maybe more insight into the issue.
When playing the IBE cd louder than normal something vibrating 
making a noise like jon-5912's story about sub's virating pan on the oven ( I'm still laughing about that ) . 
The vibration starts at about 30hz and ends about 105hz .
This is not coming from the speaker but from behind it ,
the bass is sound is not affected .
Thanks again for the info about the EBI cd , I printed out the 
freqeuncy and timing chart .

I do have a question for you beetemainia and holco ,
did you change or increase the wiring guage ?
Tom what would be you opinion on increasing the wiring gauge ?
I was thinking of using Cardas 11.5 gauge with WBT fastons .

Until I open the speaker up and inventory componets on the boards 
or I hope Rob can give me info or schematics 
I can only guess at what componts I'll use ,
but I will ask you guys what you used and why .

Happy Monday 
Rob
