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


I am considering the purchase of a set of bi-wire cables although my speakers all have single wire binding posts (the cables on offer are just irresistibly priced). Since they are finished with spades, technically there should be no problem connecting them. Does anyone have experience whether I am likely to suffer sonic degradation or electric inconsistencies when recombining wires and piggy-backing spades, though? Thanks.

Sugarbrie- I was stating that I (personally) would remove the four spades from the speaker end of the cables, mate the conductors and install only two spades or bananas. This would lessen the chances of the post loosening from cable vibrations(through the extra spade/cable spread), and eliminate a connection. I believe Bar81 missed my point. Is this the confusion you cited?
Thanks for the responses. Just to clarify a few things that led to confusion:
The pair of cables I have in mind has 2 spades on one end (amp) and 4 spades on the other (speaker). I will double up the tweeter and woofer + spades to connect them with the single + binding post of the speaker (and accordingly for the -).
In doing so, I am not trying to achieve bi-wiring benefits with a speaker that sports a single wiring terminal. I'm aware that there can be no separation of the signal.
The thing is I would like to try these particular cables, that happen to be available as a bi-wiring pair only, in my system in a single wiring mode but I'd like to save the cost of having them redone for the moment (the latter would be the better thing to do, surely)
I was just wary of negative effects that anyone might have experienced to be a show-stopper.
Thanks for any additional thoughts.

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.
