Biwiring make any sense?

@84xfirez-51 , I am not saying that is not correct, because I don’t know; and I am not saying it wouldn’t work, because if the runs of cable are identical pairs I see no reason it wouldn’t work; I am just saying that I was always under the impression that speaker cables were routed from amp binding posts to speaker binding posts as per usual, and then another speaker cable came out of the same amp binding posts and went to the same speaker but connected to the other (unused) binding posts.

But no biggy, if it works it works. As I typed, assuming all the cable runs are identical, I cannot see how it would make any difference which method you used.

With the cables I was using, I would have been unable to do it the second way. I was using one grade of Kimber Kable to hook to my tweeter binding posts, and then I was using the next grade up of Kimber Kable to hook to my woofer/midrange driver binding posts. Thinking about it, I guess I could have used the smaller grade of Kimber for the grounds on both sides, but still, I had one of the pairs made with spades on the ends for the speakers and bananas on the amp end, therefore I wouldn’t have to double any of the spades up on top of each other at the amp end. (In other words, at the amp, the woofer pair of cables was connected via spades, and then the tweeter pair of cables was connected to the amp via bananas.

True biwiring was made if you wires from the internal Xover had a separate wire from the Xover to the loudspeaker  terminal,  upgrading many speakers 

most biwiring on the terminals is fake ,a selling point 

get rid ofthe stock jumpers  if they are metal straps pure junk. You want agood quality wire and quality connectors copper is far better then cheap Brass which most are unless you have say WBT connectors  ,I have found if you connect the Speaker cables to the bottom you get a bit more if-you

I posted a link to an image for bi-wiring. Yes, my cables were the same for each pair. Using the same cables I had for many years, I immediately noted the difference and improvement listening to music I have been very familiar w like 

Famous Blue Raincoat - Jennifer Warnes

Brothers in Arms - Dire Straits

That is what compelled me to try newer tech cables like the Shunyata Venoms. I have Venoms for my interconncts.

I saw your link, @84xfirez-51 , and that was what I based my reply on.  I am pretty sure I understand what you reconfigured your biwire to.

If your speaker’s crossover design and terminals are true biwiring, yes biwiring helps. But the value decreases with increase in amp power. That means, if your amps not very powerful wrt speakers, biwiring will be very useful. The audible gains are high. E.g A low power 30 watt class A amp to drive a regular 88db speaker will love biwiring. But if your amp is a 200 watter, for the same speaker the audible gains are much lower. 
 

Richard Vandersteen has nicely experimented and explained the reason biwiring works (only in true biwirable speakers). He said the bass frequencies typically ride on the outer layer of the speaker wire and highs ride in the inner layers. In a speaker with strong bass and lot of driver excursion the bass signals are very strong and they interfere with mids and highs signal riding in the cable. That cause muddying of highs and mids. Hence biwire cleans it up. The better the amp controls the speaker, the more controlled the signals ride in the wire too

I have personally experimented and found this to be true.
