From what scott says about these "problem" in June 2003

"First, while we have the highest respect for reviewers, there are times where the methodology they employ in testing produces results that do not provide a full picture of how a product operates. Secondly, just to maintain our own sanity, we asked our engineering team to validate the operation of the crossovers, and they reported that everything does work as it is supposed to."

I only guess what methodoly applied outlaw in these case.
