@jsalerno277 "The reason is that an effectively larger diameter has less inductance since it has a larger cross-sectional area” - more important is how close positive and negative wires are, the closer wires are (twisting helps), the lower loop inductance of speaker cable is.
If Bi-Wiring is an option, should I choose Bi-wiring over single banana with free jumpers
Hello All!
Newbie here : ) I have a pair of speakers (MartinLogan Motion 40i) that have, according to the website, "dual five-way binding post speaker terminals which allow bi-amping or bi-wiring." As you can see in the top right photo of the speaker terminals in this link, the speakers came with free jumpers (the jumpers look like just a sheet of conductive metal) between the 4 terminals.

So when purchasing speaker cables, placing the best quality connection over cost, should I:
1. (Cheapest) Get single banana plugs and use the included free jumpers, or
2. (More costly but will it be WAY better?) Get Bi-wire speaker cables and remove the free jumpers.
3. Get single banana plugs, and find some high quality jumpers to replace the free included jumpers.
If it doesnt matter much to sound quality, it seems option #1 is best as its cheapest. However my goal is to get the best/most efficient connection so i suspect options #2 or #3 might be the way to go?
Many thanks for any advice!

@steve_a001 Kimber-Kable 12TC speaker cable, 8ft long, has 0.006 Ohm resistance and less than 1uH loop inductance, which makes interconnect between amp to speakers terminals “invisible”. If cable is too long (high R and L), then there will be some improvements of bi-wiring. Jumper/SPKR-terminals/SPKR-internal-wiring-crossover quality can be very bad quality, many folks will be surprised to see 0.5Ohm LPF (bass) SPKR inductor resistance, and very tiny wires inside SPKR cabinet. |
