Audiophiles have been debating the merits of speaker wire since the days of mono hi-fi. A heavier gauge of speaker wire is certainly desirable if your runs are going to be long, and usually the stuff that gets packaged with computer speakers, even the Logitechs, is marginal on a good day.
Personally, I'd go to a good hardware store and by a bunch of 14 gauge zip appliance cord if you can find it, standard 16 gauge lamp cord if you can't, and be done with it. If you were pushing hundreds of steady-state (RMS) watts through it, something heavier and more finely stranded might be worthwhile. But over a shorter run, with relatively low power, the series resistance and capacitance of standard zip cord is negligible and
in my opinion any benefits of getting something like Monster or AudioQuest cable has more to do with pride of ownership than any actual sonic differences
Just my $.02 worth. Wars have been waged over this subject and I ain't gonna get into one
