M40 Tweeter Crushed

At the end of last summer, I passed down my beloved Monitor 40s to my younger brother. Apparently, he loves keeping them topless. I can't say I blame him, but unfortunately someone crushed one of the tweeters.

We have one Monitor 30. Would it be possible to cannibalize the Monitor 30 to replace the Monitor 40's wounded tweeter? I know the face plate only has one cutout for the 30's single woofer as opposed to the 40's two, but can the tweeter itself be swapped out? Would it be cost effective to buy a replacement tweeter instead?

I know these speakers aren't anything really special in and of themselves, but they're a great pair and have some sentimental value for me. They were the first pair of speakers I owned. I'd hate to see them go because of an overzealous cleaning lady after they introduced me to the world of serious listening and even survived countless beer showers and hours of abuse at some really rocking dorm parties.

This just makes me love the dual concentric design of my Tannoy D100s even more! Totally protected behind that waveguide :)

    How were they crushed? It is a soft dome.. should be able to take tape and pull it out

    The only info I have on this is what my brother told me, so I'm not sure just how bad the situation is. I'll be going home this evening, so I'll give the tape trick a shot.

    You could also try sucking it out with either your mouth or very carefully with a vacuum.

    Good suggestions above. If there is no discernible distortion coming from that tweeter, it's probably still fine and either method above will pull it back to it's original shape. Fabric domes get pushed in all the time, by curious little hands or buffoonish, clumsy adults.

    vacuums work good on Mid-woofers or woofers but for tweeters they can destroy the dome. I would shy away from that method personally. VR3 has it sticky tape or I have used small cardboard tubes or straws and my mouth to gently suck them out.

    A little masking tape got the dent out. There are still dimples at the corners of where the dent was, though :/ Not sure if those will be fixed. Thankfully, the damage was merely cosmetic.

    I wouldnt worry bout the dimples. I doubt you could hear the difference. Now tell your bro to put the grilles back on asap.

    We've agreed that the best practice is that if he's out of the room the grilles stay on.
    There doesn't seem to be an audible difference, but it's just kind of an annoying cosmetic flaw.
