I am Not hurting anything right ??

No harm to leaving the jumpers in (unless as some people say, you will benefit from replacing them with a small length of speaker wire). I doubt seriously that you need to reterminate your cables. If your speakers are bi-wireable (because thats what the market wants), it cant hurt to take the jumpers out and use them that way. You may even find you like them better bi-wired. But if you prefer the sound with the jumpers in and all four cable ends attached (belts and suspenders), use them that way and dont worry about it.

Sqjudge, I'm confused. Regardless of whether bi-wiring is or is not beneficial (and I bi-wire in my main system), I just don't understand how the signal, current or whatever can be different, coming from the same source. Doesn't the amp send the entire signal to whatever crossover is at the other end of the circuit? And isnt the circuit completed at the crossover, which sees the entire signal regardless of what it passes on to the driver?

Sean, some speaker makers include bi-wiring terminals because the retail market demands it, even though the designer/maker doesnt think it does any good. Some people just won't take a speaker seriously unless its bi-wireable and some people have already invested in the cables they want to use with their new speakers. I wouldnt call it an afterthought or marketing gimmick.

Thanks Sndsel, that makes it a little clearer, I think. I do prefer my own speakers bi-wired and think people should just try it both ways and see if it makes any difference to them.

It was a recommended tweak to try, by Jon Risch at AA, which I mentioned previously. Doesnt work for me. My speakers sound better to me with no jumpers. But some people report that they like it. I dont know why.
