I've never heard a three-way and had just assumed a bi-amp was the only possibility with my speakers. At first I saw that they could be bi-wired, but then I figured out (and read) that bi-wiring does little if anything. Then I heard of what I now understand to be passive bi-amping, but learned that apart from adding more amplifier power, it really doesn't do much more than bi-wiring. So I am now trying to figure out whether active bi-amping is worth the trouble. Because it would involve a substantial amount of work and expense, I have ruled out tri-amping, at least with these speakers.
