  If you can't see physical damage, and it doesn't odd, it's probably okay.
  
  BTW, kids aren't the only ones at fault for this. One summer during my early college years, I came home for being out for the evening, and my father was sitting with a glass of wine watching Sports Center. "I was listening to your speakers, and I might have done something to them..." At the time I had a pair of B&Ws with metal dome tweeters, and I go over to find that he had pushed in the dome on one! "They are nice sounding speakers." My father is a very smart and educated man, so I blamed it on the wine, and luckily a replacement dome was easy to source and install...

  The thin piece is just a dust cap.

  If you leave the grills on, the tweeters are out of sight and out of temptation. If you decide to leave them off and someone does something stupid to them you have no one to blame but yourself.

  The phase plug is not a thin piece, I would have described the phase plug as the piece that looks like a nipple. :razz:

  Hi Jim,
  
  Slightly off topic: Been researching my next speakers and like my sub build thinking DIY. In my search I found you had started a pair of Statements. Did you ever finish?
