    Agreed, it displaces the sound, it doesn't produce it, which is why the tweeter itself still produces sound when the "dome" is removed, sil vous plait?

    But that isn't what I wrote, I wrote that "it displaces the air"; "displaces the sound" doesn't mean anything, sound is the result of the displacement of air.

    But, in essence, it does - though the voice-coil and magnet are required to cause it to physically move. The varying music signal passes through the wound voice-coil, this causes the voice-coil to move backward and forward within the fixed magnetic field created by the magnet and pole-piece. The dome is attached to the voice-coil and as it moves backward and forward it acts upon the air in the room, producing a wave that arrives at your ear and is perceived as sound as that fluctuating air pressure acts upon your ear-drum.

    How do you imagine the sound waves are actually propagated?

    The voice-coil moving on its own may produce some output, but it will be far from the response that the manufacturer intended. Once you have cut the dome out of a tweeter you have effectively rendered it scrap. Cut the cone out of the matching woofer and see how that works for you (however, the dome in the centre of most woofers is more of a dust-cap).

    Unfortunately I can't afford to hack my speakers at the moment I do follow your point about the woofers, but with tweeters surely the higher frequencies aren't in need of so much reverberation to make their sound? But i'm not going to argue the point about something i know little about other than from some ancient youthful past experience

    I think you are talking about a cone tweeter with a centre dust dome Yes I agree that if you removed the dust dome it'd still work & probably not sound too much different.

    Do the same thing to a dome tweeter & it'd be to put it politely f*cked

    Well done Bob - glad you got it sorted out in the end.

    I was worried it might turn into a situation like this:
