I have been using the Bose L1 Compact since the first week it was for sale. I have always used the two into one connector. I tried single cables and there is a difference using the two cables.

Also, the idea of lugging around two speakers is a bit silly. I actually did own two Bose L1 Compacts and did use both of them on gigs for nearly a year and just got tired of the extra equipment which really added nothing to the gig situation.

Unless you are playing extremely large venues the single Bose L1 is good enough.
