Help a newbie out please.... I just bought Def Tech BP2006TL's and they are very narrow speakers. It seems that there are 2 plastic "outriggers" that came with them for attaching either spiked feet or simply improving stability. The problem is that when I line up the "outrigger" in the groove on the bottom of the speaker, there are 2 holes in the outrigger but nothing to screw them into in the base of the speakers. It almost looks like to attach them I need to drill into the base?? Which I am certainly not about to do. They have a fairly decent manual I cant believe they didnt explain or illustrate anything about this.. Thanks!
