Bi-wiring sells more cable.
Check the electronic theory behind it, that What Hi-Fi? article says bass swamps the delicate treble in the cables, which sorry, Virginia - seems plausible but just doesn't happen. Bass isn't a bully and treble isn't a 98 pound weakling. For proof, look at any professional install (I mean pro audio - not boutique HT) - I've yet to see a biwired install in a professional situation. The closest I've seen is keeping a backup cable from a snake "hot" with signal just in case of cable failure for a quick swap-out.

Bi-amping however, has a use. If your amplification section is insufficient, you can buy another insufficient amp and split up the load a bit. Most of us would just buy an amp that had better handling, however.

Even Axiom themselves have admitted here (quite a while back) that the only reason the big towers are capable of bi-wiring is because of consumer demand. Big speakers have 4 terminals - customers like to see it.
