I meant do not use the tweeter adjustment binding posts located higher-up on the speaker. You can biwire the speaker to the same amp. You can not biamp the speaker to 2 separate amps to the 2 bottom pairs of jacks. You can use the 2 bottom pairs of jack for biwire only though.
The reason is because the top and bottom jacks on the bottom of the speaker are both wired to the entire speaker. You will short your amps out by biamping these 2 pairs of inputs, but bi-wiring with one amp is fine. There's no example of anyone using the much higher located tweeter adjustment input jacks, that I know of. You are more than welcome to ask Eric directly if you so wish, but he's very busy and previous requests have gone unanswered.
