Tekton Double Impacts

Not aware of and cannot find this NEW WE cable you say is being sold?

@thompsontechs Congratulations on experiencing "magic".......

The DI and [2170] are magic, I sat there last night grinning like a fool

The Zero Fidelity youtube guy has another video on the DIs. He mentions that they have semi recently had a minor voice change. I believe it was something like a 2db drop around 1000hz. He had a resistor on an alligator clip guessing was sent by Tekton. Anyone know anything about this? 

Yes. Add a 15 ohm resistor across the two 6 inch midrange drivers. . One 15 ohm resistor placed in each speaker. It needs to be placed in parallel to the 68uf shunt capacitor. The resistor should be at least 10 watts.

You will need to access the crossover board behind the tweeter array and solder it in parallel to that 68uf electrolytic Capacitor. Not easy.

Newer DIs have this resistor already. Not sure the date the builder starting adding these parallel resistors. My speakers were made in August and did not have them. I very much liked the result finding the speaker was more cohesive and smooth. Smoothness and a wonderful cohesiveness was readily noticeable. My wife did a blind a/b with the resistor in and out and MUCH preferred the sound with the resistor in place. Same with me. Not a slight difference, but one you will hear right away. My crossover is outboard so I could easily compare with the resistor in and out of the circuit. The sonic improvement was so enjoyable for us that I soldered in the Duelund 15 ohm resistor in short order. 

Dont use a cheap sand cast resistor IMHO. Parts in parallel crossover positions also matter. I used a nice Duelund CAST. You could also use Mills MRA12 resistors at just $4 each.

I want to share that Eric at Tekton was kind enough to share the value of this resistor to me. This is a very worthwhile upgrade and points to the fact that the builder is passionate about continuously extracting the very best sound possible out of his design without raising the price!

The two junctions points to solder in the resistor are easy to locate and that is good news. Since it is soldered in parallel to the small black and white 68uf electrolytic cap start looking for it.  It is located in between ( almost centered)  between the three inductor/coils. This cap is actually connected to the largest inductor/coil of the three. The point that they both meet the parts are twisted together and soldered. One end of the resistor is soldered here. The other end of the 68uf cap is the junction point for all the black (-)wire negative leads from the tweeters and midrange drivers. Easy to spot as you will see many solder connections here with black (-) wire leads from the drivers. The other end of the resistor goes here.
