>>Thank you all for valuable information. I guess bi-amp is not really practical for home use.

Probably not worth the hassle. The other point is that if you have a sub and are running your mains as "small" then you are already doing "enough" bi-amping, ie you are peeling off the lowest frequencies and keeping them out of the amplifier which handles the rest of the frequencies.

I imagine bi-amping on M60-size speakers would have caught on more in the home audio space if powered subwoofers and 5.1 recording hadn't caught on. Once you strip out the very lowest notes and route 'em to a separate sub amp there is very little benefit from doing anything more.
