Bi wire with one set of speaker terminals?

Bi-wiring comes in handy when you have two different cables to use for tunning the tweeter separate from the mids and lows.
Other that that, a single cable with matching jumper will work just fine.

It also works well where you can use Silver for the top/mids( highs and mids ) and copper for the bottom ( lows ),from the same manufacturer..I did it years ago using Audioquest Argent for the highs and Midnight for the lows..Great combination and to me this is the best way to bi-wire where you use can both silver and copper under the best situation.......

Use a jumper cable that is at least equal in quality to the SC's.

Samhar is correct. The jumper is as critical as the cables.
