To the everlasting pleasureof hard core subjectivists, you can never actually, absolutely, prove the absence of something. So you cannot absolutely prove the absence of an audible effect from passive biamping. Appears that in controlled double blind tests folks don't accurately identify a difference between biamped and non-biamped systems, though. Which means those tests did not prove there is a difference. But the nature of the undertaking is such that not proving a diference is different, technically, from proving an absence of difference.
AFAIK biamping cannot hurt anything, but you absolutely will not achieve double power (which would only be 3 dB anyway) and unless you are pushing your amps hard enough to produce audible distortion, the only slim possible benefit (keeping the higher harmonics of THD from the woofer amp inaudible by feeding the tweeter with an amp that's running maybe 20 percent or so as hard as the amp for the woofer) will not appear either.
