Here’s a little catch-up report. During the summer I got snatches of time to evaluate outboard crossovers and internal wiring. I have added some stunning KimberKable solid silver 3-braid to the mix. Some may remember awhile back when some of us compared single-polarity runs vs +/- paired-polarity runs. We were comparing amp to speaker runs and the main problem with singles was variable wire to wire distance causing transmission anomalies. But we were all enamored by the quick, uncomplicated sound of the parallel configuration.
I spoke with Ray Kimber, who wholeheartedly recommended the single polarity solution, which is now included in my trials. In the cabinet, each run can be stuck to the wall with butyl rubber goo. What a sonic treat - from the point of view of ease and lack of dynamic congestion. Kimber’s samples of AGSS 3-Braid (stranded) and AGSC(MST) 3-Braid (solid) employ 3 conductors in a braid for each separated polarity run. MST stands for Magnetic Stealth Trio. Insulation is teflon. I’ll be getting copper samples soon.
The CS1.5 is my current workhorse, having 4 relatively short runs from the outboard XO to the drivers.
