This speaker definately should be bi-wired, as it makes a big difference in the sound. The manufacturer clearly believes that this speaker sounds way better bi-wired.
I would agree.
I had a pair that I just sold because I wanted to change to Maggie 3.6R's (I hope I did the right thing!).
Anyway, I had Synergistic Research custom make a set of Resolution Reference .5 X2's by making the speaker ends longer than stock. What makes these cables somewhat unique, is that I had Synergistic custom make these with the 4 speaker ends (on each of the right and left cables) a little longer than standard so that they can reach between any speakers that have 2 seperate cabinets, in my case it was for the Von Schweikert VR4 Jr's.
These were pretty expensive (IMO) but they were awesome! I have them for sale on AG right now as the guy I sold the speakers to didnt buy the cables too.
The distance between the top cabinet and the bottom one does present some issues for an internal bi-wire.
There are several options.
* Buy mine ;-)
* Shotgun with 2 seperate sets of cables (excellent idea)
* Utilize the "Data Link" (not the best idea)
* Order your own custom made wires similar to the ones they were using at the HE2004 Show that feed the top cabinet and jump down to the bass cabinet, as somone has alreadt mentioned here.
