I have a set of klipsh promedia 2.1 set of speakers... and does anyone know how the *&@# to get the grill off this thing? I tried opening the metal panel on the side, but all I can see is the bottom end of the screws hold hte sub... but there is no apparent way to remove hte grill. I dented it slightly and sometimes when the system bumps really hard, the area aroud the cone of the sub taps the grill and makes an annoying noise... I'm not turningh it up for now... but I woudl really like to get this thing off so I can take out the dent. Any help would be greatly appreciated! Thanks!
