bi-wire cables on single binding post, sonic loss?

I was just wary of negative effects that anyone might have experienced to be a show-stopper.

Absolutely no negative effects. You can wire this up and it will work great provided you don't mix +/- or red/black on the four spades at the speaker end (which could short out your amp if you are not careful).

Using bi-wire cables on a speaker with one pair of terminals, does not give you bi-wire benefits.

On bi-wireable speakers the highs (tweeter) and low (woofer) terminals are completely separate inside and outside the speaker. If you only connected cables to one set of terminals, the other speaker driver would not operate; it is not getting any signal. Some manufacturers do it because there is sometimes a benefit in how the crossover works when the two speaker drivers are separate. There are actually Tri-wire 3-way speakers out there as well.

Some people goes as far as to customize the sound further by using different brand/type speaker cables on the higher and lower terminals on bi-wire speakers. Others don't care and just use the jumpers that come with the speakers, allowing you do use a regular pair of cables.

There was no confusion, it doesn't matter if you double up spades or otherwise, there's zero difference over a SC run. Bottom line, go ahead and enjoy.

btw, above I was talking about the highs and lows for the bi-wire cables I have, the speakers (Focal Alto Utopia Be) have a single pair of binding posts.

Bananas degrade the sound
