You can try the tape method to pull out the tweeter, or, with the speaker disconnected try sucking it out. I advise against the vacuum cleaner idea since vacuum cleaners have been known to rip the whole thing off...
It depends on how badly creased it is, but generally I'd tell you to change it. they're not expensive. If your daughter is likely to make the mistake again, you can talk to Totem about getting grilles for the Sttafs. One of the screws on the main drive unit undoes and is replaced with a special one with a tube on the end that allows you to clip the grille to it. Same for the tweeter unit.
I'm not sure how they sound with grilles on, but out of sight should hopefully be out of mind? And you can always take the grilles off for critical listening.
I was demoing Forest not long ago with pushed in tweeter. I have called totem - Nico (very nice and knowledgeable tech person). He told me that poke (not hole) would be only detectable with good quality meter. It does not affect frequency just a bit of dispersion. But it would be virtually not possible to her this. Replacement for Forest was $140can so for Staff would be under $100 I imagine if you really want to do it.I have 6 year old son and I've placed strategically flower pots and some statues... in front of Arro's to block direct access. But of cause woofer and tweeter have clear space in fron of them, flower pots are smaller. Pablo
Hmmm, my brother-in-law is coming along with wife, 10-year-old son and 4-year-old daughter for a couple of nights. I think I'd like to remove the turntable armtop and cartridge (easy to do with an ARO), but I wonder if my wife would take offence at that...
Hmmm, £3000 cartridge versus 4-year-old and 10-year-old. May need to talk to the wife. Not worried about the speakers - the tweeters have a metal grille on them, but the tonearm is very delicate...
I'm reminded of something a football fullback said to me during pre-season camp as I was wrapping bags of ice on both shoulders, elbows, knees, and his low back -
As for the kids, they're well behaved (turns out 4-year-old is actually 6-year-old, hey what do I know?) so I'm not that worried. Art, the wire mesh grill on the RainMakers should be strong enough to withstand most kids' probing fingers. Then again...if they're not in sight, they're not in mind.
My speakers will not be moving. Too heavy and I'm too old.
