Thiel Owners

@tmsrdg, It was a long time ago, but when I lived in NYC one my favorite dealers carried amongst others both Spectral and Thiel. They often rotated both in and out. I think this was up to the 2 2’s and 5’s time period, but pre co-ax. 
My recollection was that the combination demonstrated both of their attributes, but the Spectral while capable of handling the low impedance of say the CS 5’s, was happier with the above 4 Ohm and above Thiel’s.
 The Spectrals were admirably lighting fast, very detailed, smooth, with no electronic smear what so ever. Ultimately I found them a bit thin, threadbare and bleached. I can imagine them having their admirers though. 
 The Spectral’s were said to be rather particular about matching pre’s and speaker cables, with their own pre and MIT cables being very strongly recommended!
 Hope this helps.

Keep in mind when you compare the bass response of different speakers, it is hard to eliminate the room response of the different speakers. Several times I was ready to replace drivers of my 3.5 only to find out with near field measurement that the drivers were perfect but bass nodes and boundary effects caused the distortions. When I replaced the 3.5 with the 3.7, the room effects also changed significantly.

it seems that the 2.4 crossover upgrades are pretty well finalized now and that a lot was learned regarding upgraded components and the effects on how the speakers sound. 
Since I own 3.6s, I’m interested in learning how much of the info gained from the 2.4 upgrades will be able to be applied to a 3,6 upgrade. Will it be necessary to start from scratch in designing the 3.6 crossover upgrades, and is it realistic to hope to be able to actually buy a completed crossover package from Rob G. In the near future? 
Thanks!

tomthiel,

Have you already had some experience with the Jantzen Wax coils?

Holco - Thiel used Jantzen and ERSE wire coils as equivalents.I have ERSE foils on hand and some Jantzen Wax on order.I will compare them directly, but not yet.
