Tuning with a drain wire? Who'da thunk it?
Chris (and Alan Maher) both contend that the gauge of the earth/ground wire from the TI-Shield definitely makes a difference in the sonics, with both claiming that the thicker you go toward 10 or even 8 AWG, the thicker the sound that results.
I figured that the 3 individual 14 AWG wires (each about 3.5" long), that terminate the 12 AWG drain wires (total 35') from the TI-Shield on the speaker R-Cs into a star at the ground pin of the AC plug, would equal about a 10 AWG wire if totalled together. So I did that to see if Chris was right (as Alan had suggested too) that the gauge of the end of those grounds would determine the leanness or heaviness of the sound.
What I did was simply to join all of them together with one wire nut. About the only difference would be that the star point would be 3.5" from the ground pin and the effective gauge would be much greater.
I'll be damned if it didn't add real weight to the mids! Then I noticed that it was also beefing up the bottom end. So I was trying to critically listen to see if any of the detail and clean sound had gone south. So far they don't seem to have. Overall it's thicker, but as Chris suggested, more "musical". Can't say as I prefer this yet, but it's different enough to warrant an extended test.
I now have a choice of 3 effective gauges: with one 14 AWG wire (terminating each of the 12 AWG drains), or with 2 together making it more than 12 AWG, or with all 3 together making it around or greater than 10 AWG.
Why wouldn't I now experiment with the in between value and report that to all of you? Well, my wife has been staying home this evening making lots of noise, so critical listening is dead for tonight. But you can be sure I will do this quick and dirty experiment and settle on a final configuration.
Who'da thunk it? Not me for sure!
