Many speakers offer a bi-wiring connection option. Bi-wiring means connecting two lengths of speaker wire to each speaker, one to the woofer section and another to the midrange/tweeter section. Bi-wiring a speaker is an inexpensive way to improve sound quality by running two identical lengths of wire to each speaker, or purchasing a set of bi-wire speaker cables.
Bi-wiring reduces the negative effects of the impedance differences between high and low frequencies traveling through a single wire. Bi-wiring speakers with separate wires reduces the interaction between the two and improves sound quality.
How to Bi-wire Stereo Speakers:
Not every speaker can be bi-wired. A speaker must have separate terminals for the woofer and midrange/tweeter. Sometimes they are marked by the designation ‘high’ and ‘low, and sometimes they are not marked at all. Be sure to consult the owner’s manual for further information before attempting to bi-wire your speakers. In addition, the bars that connect the terminals must be removed before connecting speaker wires to prevent damage to the speakers or amplifier.
Benefits of Bi-amplifying Stereo Speakers:
Bi-amplifying a speaker is another way to improve sound quality, but is a more expensive option because separate amplifiers are required for the woofer and the midrange/tweeter section of each speaker. In addition, rather than using the passive crossover built into the speaker to split high and low frequencies, an electronic crossover is recommended to get the best performance. Bi-amplifying a system allows the best amplifiers to be used for the bass and midrange/treble but because of cost is used mostly for very high-end systems.
How to Bi-amplify Stereo Speakers:
Bi-amplifying stereo speakers also requires separate terminals for the woofer and midrange/tweeter on the back of the speaker. Be sure to remove the bars that connect the terminals before connecting the speaker wires to prevent damage to the speakers or amplifier and consult the owner’s manual.
