Bi-wiring
As we’ve already mentioned, some of our speakers are “bi-wire capable.” This means the speaker system is designed to allow two runs of speaker wire from the amplifier.
The rear panel of these speakers includes two sets of connections, each with a “+” and a “-“ terminal. Both “+” terminals are connected with a jumper, as are both “-“ terminals.
If you are using conventional speaker wire and do not wish to bi-wire, do not remove these jumpers. Simply choose one set of terminals and connect the speaker to the amplifier as previously described . You can pick either High or Low terminals. Because they’re joined by the jumpers, it doesn’t make a difference.
If you want to bi-wire, first remove the jumpers.
If you’re making “home-brew” bi-wire cables, measure two identical lengths of dual conductor wire. At the amplifier end of each pair, strip about ¾” of insulation from each conductor. Then connect the “+” conductors together by twisting or soldering them. Do the same with the “-“ conductors.
Do not do this at the speaker end!
Observing proper polarity, connect both “+” conductors (now joined) to the “+” amplifier terminal. Then connect the joined “-“ conduc- tors to the amplifier’s “-“ terminal.
At the speaker end of each wire run, connect one length of speaker wire to the Low termi- nals. Remember to observe proper polarity by connecting the “+” conductor to the “+” termi- nal and the “-“ conductor to the “-“ terminal.
Now do the same thing with the other length of speaker wire but this time connect the conduc- tors (“+” to “+” and “-“ to “-,“ of course) to the High terminals.
