    How to replace ferrofluid in ADS Tweeters & Midrange

    I've been on the hunt for a comprehensive video guide on replacing the ferrofluid in ADS midrange and tweeters. Recently, I purchased a pair of Braun L810 and L780 speakers. The L780s, while cherished (I'm trying to be polite to the previous owner(s)), show their age (see photos). My goal is to...

    KEF 105/3 Tweeter Ferrofluid Replacement - NT25 SP1240

    Acquired a pair of KEF 105/3 a couple of months ago. The mid and bass sound fantastic, but not the highs. It feels kind of dull and not as lively as the 107's tweeter (T-33) - I AB'd the two speakers. After reading a lot of postings from the internet, I suspect the FF may be the culprit. I...

    Beginner ferrofluid question.

    Alright so I got some PSB image 4t towers used and noticed right off the bat that they sounded terrible contrary to all the fantastic reviews. I ended up tracing the issue to the tweeters. Seeing that stock replacements aren't available and if they are are far more than I want to pay I was...

    Where to buy replacement foam w/o a full kit?

    I have a pair of EPI A70s I got for free (!) because the bass drivers need refoaming. I have glue & other supplies for the task, just need the foam.

    DA PS-10 Low Tweeter Output

    Hello fellow AKers! I’ve got an odd one right now and I need help. I managed to get my hands on a pair of DA PS-10s after reading good reviews on them. I love their design, very unconventional. I gotta say, these speakers have been nothing but trouble from the very start (hooray for COVID, I...

    Kef T52B - 1072 - Ferrofluid?

    Hi, Been doing research, can't find a definitive answer, but I think the answer is no, it does not use ferrofluid. I pulled the tweeeter, removed the dome, "cleaned" the voicecoil gap looking for ferrofluid and saw no gunk or discoloration. It also appears that the former on the voicecoil is...

    EPI 100V Ferrofluid Tweeters

    Long time lurker, first time poster. I grabbed a set of EPI 100Vs for a steal of 25$. The grills are darn near perfect (one is missing the EPI wave logo). The veneer is in great condition, save for some sliding scratches on the bottom. I pulled the covers and the woofers foam surrounds...
