Bi-Wiring

All of our 1723 speakers (except 1723 Height S) can be run in Bi-Wiring.
For that, you just have to remove the jumpers between the terminals.
It has no real sonic benefits, provided you already have a good wire gauge cable, but you do not have to re-terminate or switch the cables you might already have. 
Some people also prefer the looks of having a Bi-Wire cable.
