However, there appears to be no visible / external 'bridge' between the two pairs on the back of each speaker. IIRC, if I want to use these WITHOUT biamping, there should be an external bridge, right?
If that is correct, it may be easier to simply biamp ( which I can do) rather than try to find or jerry-rig bridges.
Sorry if this question reveals my profound ignorance of all matters bi-amp, it's just not something I've ever dealt with before. I searched the forums here and elsewhere, but no luck. TIA for any guidance!
