I am supposed to install two Wiis in a sports bar soon. They will be feeding two LCD flat panels mounted side by side with the Wiis on a shelf on the other side of the wall. Now, I have used the Nyko wireless sensor bar on another install (a single Wii) with no problem. I will be using that here as well. But given that all the sensor bar is for is to provide a point of spatial reference for the controller during menu operations, is there really any need to have two or can I just install one between the two screens?

you need 2 because you are hooking it up to 2 tvs.

Technically he could get by with one.

They only thing that might be a bit weird is that the aim for the pointer would be a little off to the side, between the TVs, instead of right at them.

It depends how far the TVs are from each other.

If they're literally side-by-side, you could probably get away with one sensor bar, but the aiming may be a little skewed.

If they're any distance apart, however, you'll probably need one bar per TV.

They will be about 12" apart. So I'm thinking that just one in the middle would work.

try it and see if it works, if it doesnt it is easily changed and you only waste a trip to a store
