I did not remove the tweeter grilles. Not only 'cause I'm not into advanced "tweaking" but also because of the risk of damaging them. (Over)Enthusiastic guests are bad enough already ("what's this? a karaoke microphone? Can I try it?") So far no harm done and I intend to keep it that way :).
No loose screws either - BTW - how long does it take before one needs to tighten them, if at all?
