Biwiring ?
The following is a statement by Robert Harley in the current issue of
"The Perfect Vision". Quote: Connecting your speakers with two runs of loudspeaker cable (if your speakers have two sets of input terminals) provides a small but significant improvement in sound quality. One pair of the speaker's input terminals is connected to the woofer,and the other pair to the midrange and tweeter (or just the tweeter in a two-way speaker). In a bi-wired system, the power amplifier "sees" a higher impedance on the tweeter cable at low frequencies and a lower impedance at high frequencies. The opposite is true on the woofer half of the bi-wired pair. This causes the signal to be split up, with high frequencies traveling mostly in the cable driving the tweeter circuit, and low frequencies conduced by the pair connected to the loudspeaker's woofer circuit. This frequency splitting reduces magnetic interaction in the cable, resulting in better sound. If you have the ability to bi-wire, it's worth the cost of an extra run of speaker cable. You can buy bi-wired cables with a single pair of terminations on the amplifier end and dual termination pairs on the speaker end. Be sure to remove the "jumpers" that connect the pairs of speaker input terminal. Unquote. Is this true about the amp seeing the differences in impedance ? And is it audible ? -=Bill Eckle=- Vanity Web Page at: http://www.wmeckle.com |
