Some feel that each element (woofer or tweeter) needs a specific type of speaker wire, and those who say that are often wire manufacturers. They could be right, but the dude who designed my speakers told me they were "more coherant" single wired, and he was right (tried both ways). I think it has to be a speaker-specific thing, and I understand that one run of excellent single wire is better than 2 runs of mediocre bi-wire…for whatever THAT'S worth. It would make sense to have very good internal wire in your speakers to make bi wiring less of a big deal as a single wire run is split anyway after the crossover (or high and low pass elements) does its thing. Also, cable break in is interesting as it would seem you need to listen to it throughout to determine if it's ready for prime time.
Speaker Break In Question - going from single wired to bi-wired
I own a pair of Wilson Benesch Square 5's and have had them hooked up as a single wire connection for the past year until recently when I had my speaker cables re-terminated to be bi-wired. The question I have and I do realize that the cables themselves need time to break in, but do the terminals themselves and any associated electronics in the speakers also need break in time due to the wiring change ?
