    Hey!

    In the process of coaxing a Ragin' Cagun out of a Pro Junior, I pushed in the dome. Will it change
    the sound?

    And is there a way to pull the dome back into shape without damaging it more?

    Thanks!

    Is there a tape sticky enough that could stick and pull it out?

    You could try the good old vacuüm cleaner trick.

    Thos big screen domes will do that. Take a sharp pin and stick the tip carefully in the dome, pry the dome out. The tiny hole will disappear. You may have to do this a couple places. Will it stay out though? maybe. Screen domes or "H" domes tame the ultra highs a bit.

    All I can add is that I've had a few speakers with bent domes, and they still seemed to work fine. My guess is that it may affect the dispersal of high frequencies if you were into measuring such minutia.

    I don't believe it will affect the sound. I have had a couple of spkrs like this and they sounded fine.

    Be careful with vacuum cleaners, things can go wrong in an instant. I've had luck putting a thick sock or two over the end of the vacuum hose, to prevent a tight seal that could wreck the cone in a flash.

    Tape usually works. Start with scotch tape or electrical tape, something not too aggressive. Duct tape is the last resort, but watch it, it can stick to the cone savagely enough to damage it. Wrap a loop of tape, sticky side out, around a finger and take your time, gently working the dome back into shape.

    On the other hand, It really does not affect the sound or performance of the speaker. The dome is mostly to keep dust out of the voice coil.

    Edit: I have to learn to type faster! Looks like you fixed it while I was writing. :)

    The sock idea is a good one. Wish I'd done it!

    The vacuum hose was a little dirty and left a ring. The dirt cleaned right off, but that's a step I could've skipped if I'd thought of using a sock (or cleaning the hose).

    Next time . . . .

    wow, that's the second one today!

    i've done the pin trick and it worked fine. i was too paranoid to do the vacuum but i can see it might be safer with the sock.

    play music!

    Glad the vacuum worked. It didn’t for me. The glue one intrigues me, but I didn’t have the guts.

    Needle worked really well.

    1st - I have a pair of 8" studio monitors and one has a pushed in dome, amazingly it doesnt seem to affect the sound at all.

    2nd - I tried the pin trick sometime back and the plastic dome was too thick/hard to be popped out by a pin.

    Maybe I will try the vac and sock. Good tips.
