What is Bi and Tri Wiring?

Bi-wiring involves running two separate speaker cables per channel between the amplifier and the speaker. Tri-wiring works in a similar way, using three cables per channel, but requires a three-way loudspeaker with three pairs of rear terminals per speaker. Some audiophiles suggest that separating the signal paths can help reveal finer details, although the evidence for this is not conclusive.

If you plan to bi-wire two-way speakers or tri-wire three-way speakers, make sure to remove the metal links on the back panel. For tri-wiring our three-way speakers—where one set of cables serves the tweeters and midrange, and another set serves the woofers—remove the bottom link but leave the top link in place.
