thanks to all so far. again, this is why i love this site. i'll consider your recommendations (the penny solution is definitely the most creative). As for whether "i should be using the spikes" i appreciate your take GS5556. I found that there was a noticiable difference when i put my old 3.6s up on spikes so i was just assuming the same would hold for the 6s. Unfortunately, i am limited in terms of speaker placement (they are close to a wall behind them and not far from walls on either side). Perhaps in this situation getting the speakers up on the spikes seemed to open up the sound (at least they did for the 3.6s) and provided a cleaner, less muddy bass).
anyway, thanks again for everyone's help.
