Speaker wiring question

I'm guessing it doesn't matter if the bridging brackets are attached. Just wondering why you would want to do that?

Keep connections as designed on bottom end & you will get much better performance if you swap out those horrible jumper bars for some real cable jumpers...

Not much of a difference. :) Just don't cross the streams.

I would be curious to see if anyone ha measured the resistance (etc) across stock bridge bars compared to jumpers.

Also, for my own benefit, is there any downside to making jumpers out of the same speaker wire I am using? In other words, for my low end system I bought 100% copper, low oxygen 12 awg speaker wire. I guess the questions are 1) Would it hurt anything to use it as a jumper? 2) Is there any chance it would improve anything (in low end Polk Audio 3 way towers)?

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
