Thiel Owners

Tmsrdg - my knowledge of the SI-1 Integrator is all hearsay from the same sources and reviews as you have. I might add a little more: that Jim and later operatives after his death tried unsuccessfully to develop a troubleshoot-repair operation. Jim was a master intuitive repairman - he could troubleshoot most any circuit in a few minutes and fix it. I don't know what level of effort was put into solving the repair need for the various electronic compontnts. Short answer is that I know very little about the SI situation in particular, but that in general I am working toward a comprehensive repair solution.

One final SmartSub question: if I were to use one of the Thiel SmartSubs with my 3.7s, would I need, foregoing the SI-1 Integrator, the passive crossover "tuned" to the 3.7? Does such an item exist?

All

in my travels and auditions over the years, I can attest, REL is a very nice solution for those looking to add a subwoofer (or 2) in their system.
The older models were not sourced to china. 

Happy Listening!

Todd - the PXO creates an actual designed crossover with the 3.7 etc for a seamless transition. I find it inaudible. Rob may have it. Or if you find any PXO, he can reconfigure for the 3.7 etc

Thank You for weighing in on the SmartSub / SI-1 integrator.
Do you have any of these Thiel products in your Hot Rod garage?

Happy Listening!
