Proper connection for Snell B Minor speakers

Is there anyone in Audiogonland who knows the proper way of connecting a pair of Snell B minor speakers to a single Amplifier. The connections on the rear of the speakers have 2 sets of connectors. Going from left to right,the first pair of connectors read Low (Presumably for the woofer), The 2nd pair of connectors read high (presumably, for the midranges and tweeters), this is fine for Bi-Amping, (using two Amps). My question is when using a single amp, which pair of connectors are used, High or LOW ? Thanks
