To Biwire or not to biwire

The last three sets of speakers I owned were bi-wireable. I started with jumpers, but soon went to bi-wire and have never gone back to the jumpers(which were good cable too).

I have been very happy with the results of bi-wiring and have no intention of going back!

Bi-wiring can work depending on the cables and the speaker. I have also found that a single wire with jumpers can be just as good for a lot less money.

I have identified one theoretical reason why biwire may be helpful, Forget about the Hot speaker wire: look at the return. The return terminals of the woofer and tweeter are tied together, and then returned to ground through the non-zero impedance of the speaker cable. This provides a mechanism for the two drivers to interfere with each other. Separate return wires would eliminate this.

Another thing that I have done, and which seems to be a success, is to replace the tweeter padding resistor with the resistance of small-size tweeter cable. In my case this is easy to do, because the tweeter padding resistor is externally mounted and its value is easily changed to suit listener preference. With my MG 1.6 I like one ohm. So, I made the tweeter wires so that they have one ohm, round trip. The main advantage of this approach is cost reduction. I was able to biamp three speakers for about $8.50, and I still have some wire left over.

Did biamping help? Don't know. They sounded good before, and they still do.

I've never heard a difference biwiring unless I used dis-similar cables to act as a poor man's tone control, which works by the way, at least until you can afford to by a proper matching amp for your speakers.

IMHO, biwre makes no difference except if you're using very thin speaker cable ( double the band width helps in this case.) Biwire is more for bi-amping and I have not heard any good bi-amping combo in 3 systems. It just doesn't sound natural ( not in sync ) to me. Just make sure you have good connection ( a good pair of jumper cable ) in between the binding posts and concertrate on a good pair of speaker cable.
