I just purchased two Polk RTi8 towers to be used as front speakers. The description for these speakers mention that they have 5-way binding post terminals. I realize that bi-amping is running two seperate amps into each speaker (one to power the low end, and one to power the high end). Though, I am only using one amp, so my only option would be to "bi-wire". Now, I am not totally sure that I know what this is. Does it mean running two wires from each '+' and '-' terminal; one going to the low end (woofers) set on the speaker and the other going to the high end (tweeter)? Is this very advantageous over conventional wiring (only using one set of +/- terminals on the speaker)? My guess is that I would be powering the tweeter seperate from the woofers, thus not utilizing the speaker's crossover, but I still do not know why, if at all, this may be better than a traditional hook-up. My receiver is a Sony 100X5 DD ( if that matters). If anyone can recommend how they think I should proceed with the hook-up of these speakers, I'd appreciate some help. Also, all information regarding advantages and disadvantages of this type of connection would be great.
