Try reading Jon Risch's website regarding the "technicalese" on bi-wiring.
As to bi-wiring feeding the same signal to both sets of terminals, that is not necessarily so. On a speaker that is TRULY designed to be bi-wired, the two sections are completely independent of each other. Using the factory supplied jumpers simply ties the whole circuit together. Once the jumpers are removed, you now have two seperate frequency selective paths for the signal to take. While this is the type of "bi-wiring" that MAY result in sonic benefits, it would be negated by using an "all in one" type of bi-wired speaker cable. You would literally need a seperate run of cables for the lows and a seperate run for the highs to achieve optimum results.
As to speakers that were designed for bi-wiring as an afterthought or as a marketing gimmick, you might not gain anything other than the lower resistance of using more wire as a conductor. In itself, this is not a bad thing but hardly worth the extra money. Sean
