"Every pair of these full-size bookshelf speakers is measured and matched to within 1 dB" (from description) Pair matched to what within 1dB? Am I missing the point, I thought dB is a unit to express the ratio?
"the 3-5db channel differences on normal production units are an issue" (from Will) Oh really?! 5dB almost four times the difference in power ratio.

Matched to each other, to ensure the output between both are as close as possible across the frequency range.

"3-5 dB channel differences...." is a range, not a ratio. dB is not expressing a ratio (although I guess it could be expressed as a ratio somehow, but that's not the point here (power ratio?)). dB (decibel) is a measure of SPL (sound pressure level) or loudness. What is being measured is how loud the speaker is at a given frequency. At any frequency within the specified range, if speaker A is more than 1dB louder or quieter than speaker B, then the speakers are not considered to be a matched set.
