No criticism was meant, David; searching can be difficult(impossible?)at times. Another comment that can be added is that, contrary to the statement quoted from the manual, removing the connecting bars doesn't make the high and low sections of the crossover separate; they already are separate and have to be to send the high and low frequency drivers the right frequencies in normal operation. The reason for removing the connectors is that the power doesn't know that it's supposed to go only into the speaker, and if the connector was still there when "biamping" it would also go through the connector, up the other speaker wire and into the opposite channel, probably damaging the output transistors there.
