    They're worth anything from 50 to 200 depending on condition including cabinets and electronics.

    I don't think ferrofluid was used on that generation of Audax tweeters.
    Mr. Tact!

    Main system: MMs/ADCs/Low output MC's/One rare Japanese SUT/One scarce British phono stage/various tonearms/hefty Japanese DD TT and hefty Japanese BD TT and small British BD TT. 4 CD players/2 jitter buster/2 DACs/Valve buffer. TVC stepped attenuator or valve pre-amp or solid state pre-amp. Current dumping power-amp or either of two Class A SS power-amp or Class A EL34 valve monos or big Japanese (part Class A) integrated. Big dual concentric speakers/Smaller dual concentric speakers/Two way British compacts and full range speakers, amongst others. And too much more to list!

    Quite possibly. After all, you have nothing to lose by trying it out.

    Id say whatever you are willing to pay on a refurb, go to a shop and listen to new speakers at the same price. If they are better than yours it's probably a no brainer what to do. I'd heavily bet that whats possible now at this price is much more than you'd get in the 80s with economies of scale in production now etc.

    My incling would be you'd probably be throwing good money at bad by refurbing them. If you want to improve sound I'd buy new ones.
    Speakers : PMC Twenty5 23's

    Cyrus Gear : DAC XP Signature / PSX-R, Mono X200 Signatures, Stream X Signature, CD-T transport

    Chord Cables : Signature Tuned Array XLR, Epic Reference Speaker Cable, Anthem tuned array and Clearway digital coaxial

    By the way, I used to sell the full range of Audiomaster speakers and have taken many of those tweeters apart.

    Hmm. I'm assuming these are an HD100 D25 variant. If so, I see no mention of ferrofluid in the spec. This model dates back to the seventies and ferrofluid was not in general use then. (which is why I like old tweeters)

    I'm talking about Martyn's MLS4's by the way.

    Walpurgis - you are incorrect. Apart from my previous comments, I still remember the original blurb published in the press announcing the MLS4 which incidentally was launched after the MLS5 and which used the same tweeter.

    By the way, there were 2 variants of this tweeter - one with and one without ferro fluid. Audiomaster, along with many other box stuffers of the time, used the ferro fluid cooled variant.

    Could be. I wasn't aware of that though.

    I might take the front plate (+ dome) off my last pair of HD100 D25 units that I still have tucked away and see what they have in the coil gap.
