Thiel Owners

I engaged in an email exchange with Rob last week re upgrading the caps on my 3.7s.  He told me "To upgrade the CS3.7, a 76uf, 151uf, and a 16uf cap would need to be installed in each cabinet." I was unable to find these values. He then suggested "The values I listed are the values for upgrading the CS3.7. It is possible that the capacitors may have to be purchased with the values described (NB: in the catalogs). For example: The 76uf CSA cap may have to be summed from a 75uf CSA and a 1uf CSA cap. The 151uf cap may have to be summed from two 75uf and a 1uf. The 16uf CSA cap may also have to be summed from a 15uf CSA and a 1uf CSA."

There you have it. I'd like to do this, but do not have the technical acumen. If Thiel Service offered this, I'd jump. Also, there a lots of varieties of caps out there, and it's a little scary for me that I might alter the speakers in a way I did not like!

@tomthiel Thanks for the clarification. This pic

shows "Jim Thiel Signature" versions SA 28uF 630V and SA 14uF 630V. I cannot see a 1uF cap in parallel. The values on the woofer section are not evident.

I did not see these values online at Madiscound or Partsconnexion. Maybe I didn't look closely enough?

Also, is the crossover accessed thru the passive radiator or bottom panel?

@dgarretson Thanks for the reply. So, are the CS2.4 values available to the public? I will contact Rob Gillum for more info.

@tmsrdg Thanks for that info. Looking again on Madisound in the Clarity Cap MR 400V (is that enough voltage?), I can get to 28 uF with a 27 and 1 uF in parallel. For 14 uF I need the 12 uF and two 1 uF caps.

But given that I already have the Clarity Cap SA version in the coax, I should start with the woofer section.

beetle, it is likely that my CS2.2 cabinet design persisted to the CS2.4. If so, the enclosure bottom dismounts with screws from the bottom of the base to expose the crossover mounted on the inside of the base.
