Anyone know whether or not the early (1978) Danish Peerless tweeters (KO10DT?) contained ferro fluid?

I have searched the forum, but find only conflicting or ambiguous information.

    Nope on Danish or USA made ones. If you were to open one up just to look you could lose the voice coil positioning.

    I have never experienced that with a tweeter with a removable faceplate? There are usually tabs that position the voice coil? With an inner frame

    Is the peerless different

    In the Peerless the dome/voice coil are glued to the faceplate and there are 4 oversized screw holes that allow centering of the voice coil in the magnet assembly. No tabs. No alignment pins or anything.

    Interesting.

    I hope it doesn't use ferro fluid then 😬

    No ferrofluid in the Peerless.
