Just a simple question; If your speaker is biwireable and you choose to do so with a pair of biwire cables, does that change the the speaker's efficiency versus a speaker that is wired with a pair of jumpers?
No.
Would using two different sets of wiring (one going to each speaker terminal on a biwreable speaker) also effect efficiency?
No.
I am wondering if the differnt topologies of how current could get to the crossover would effect the efficiency of a biwireable speaker. Thanks.
First, loudspeaker efficiency does not depend on current.
Second, even if it did, biwiring would make no significant difference;
Using normal wiring there's a junction at the speaker.
Using biwiring there's a junction at the amplifier.
As long as the gauge of the original speaker wire is large enough, biwiring should make no practical difference in the current (or much else, for that matter).
Biwiring is simply moving the junction a couple meters from the speaker to the amplifier. I'd be surprised if you can find a reference that measures this movement of junction position as something that has a consistently audible effect on the final sound of a loudspeaker system.
