you slid the side rails off, right? Once that's done, the bottom grille should be just stuck on with double sided tape... unless previous owner(s) did something to keep them from sliding down.
I can't get anything to move. I've really just tested a nudge here and there tho really. Just got them a couple weeks ago and a woofer is blown so I wanna break them down and clean them up. The upper panels are in good shape but they've been stored a while. Which way SHOULD the sides slide off?
