    Kef ???

    I found those speakers in the bottom of a friends basement... never saw this before, oval woofer made in some kind of thick styrofoam...
    The crossover (mounted outside the box ) says KEF.

    Anybody familiar with those?

    Keep them.

    The three drivers are sought after. ;-)

    Oval flat driver is B139. Great innovative bass driver.
    Mid is the notorious B110, as found in the Rogers LS3/5A, as supplied to the BBC.
    Tweeter is the sweet T33, aslo found in Roger's LS3/5A

    Keff

    This might help http://www.hifiloudspeakers.info/spe...wforum.php?f=1


    Keff are the speaker that really held up the JBL migration into the UK market . IMHO , the sound is the closest to JBL I have heard.

    KEEPERS !

    A very nice collection...

    I have fond memories of the KEF 105... is that a recent photo or from years gone by? If it is recent, I am wondering how the bextrene woofers are holding up... I recall they had aging issues.

    They were certainly near the top of my drool list back in the day.

    Hi Widget. Shots are from 2 years ago. I had four of those B300 drivers and none were sagging. The were rotated once per year. I still have the pair of Cantatas and Calindas. I sold the 105/2 last year.

    The B139 is great in a transmission line tuned to 25Hz

    Tweeter looks like its a T27.
    The B139 does perform well in a TL but dont expect high levels-from any of them.
    Popular in the 70's but low efficiency, a bit soft sounding with silky smooth top end
    made for a British hifi, warm, pipe and slippers sound-as far from JBL as you could imagine.

    There's a review of the new KEF Blade speaker in The Absolute Sound magazine this month (April 2012), that includes a very good history of KEF that's really interesting.

    Wilson Audio used the KEF B139 in their WAMM system and have built up a stock of them (120!) to service their old speakers into the future (the B139 is no longer manufactured). Here's a video talking about it, among other things: http://www.youtube.com/watch?v=cf1-5cGVs8g

    There's also a book on KEF by Ken Kessler, but it's a little pricey: http://www.amazon.com/KEF-50-Years-I...1300001&sr=1-1

    Nice find!

    Ok, got them playing right now.
    First impression was.... bose... oh no! (if there's no highs and no lows it must be bose)

    I realized I had to give them a lot more high and low boost that I would give my old L100s, Once I did give them that boost, they reacted very well to it, no boominess, no harshness, they are quite soft indeed and not hard to listen too.

    But they do need a serious EQ boost.

    All the drivers are working but one tweeter has a pushed in dome. I took it out partially with masking tape but still some creases remains.
