It also depends on the type of speakers and how it was designed. If you have a small two way monitor, then the difference is probably minor.
If you have a three way speaker AND if it was designed such that internally, there is a separate run for the bass driver, and a separate run for the mid and tweeter, then you probably will have some nice improvement. BUT if for whatever weird reason, they combine the bass and mid in a single run, then the tweeter in a separate run, then it sorts of defeats the purpose of bi-wire and you may not get much improvement.
In most cases, it's the big bass driver that is guilty of modulating the rest of the drivers and that is why you need to isolate it be it bi-wire or bi-amp. Better yet, if you could isolate the bass and give it its own amplification, it's even better. I once bi-amp my speaker, and there was a significant improvement in detail, definition, soundstage and pretty much everything.
