Speaker wiring question

Still just wondering if you're not biwiring does it make a difference if you're using the low or high posts?

Thanks for the replies.  Freediver:  they are actually cable jumpers and not brackets.  Why do you think I would get much better performance if I connected to the bottom (low end) just curious.  All the illustrations for non biwiring do show connections being made on the bottom.  just wondering if there is a sonic difference or to  just to keep things uniform.  Would it then matter if you connected to the high end instead? I am going to experiment but don't think I'll be able to hook things up again for a few days

Both the speakers and integrated were recently purchased (used) and I listened for a couple of hours again today this time connected to the low posts and things did  sound better but I also used different Interconnects and am wondering if that was the reason.  I'll continue to experiment and may give biwiring a shot down the road as well 

I wanted to use the same ones I used the previous time which happened to come with the integrated I just purchased ( Denon pma 2000 IVR - pretty impressive unit incidentally) but forgot where I put them and used my Morrow IC instead   They'll turn up and  Like I said I'll continue to experiment.  The speakers are Platinum Audio reference one's and very impressed thus far with these as well
