An impulse purchase on ebay - a pair of KEF Cantata G4s,
very cheap.
Now in the garage so I can listen to the BBC while
tinkering.
But listening to some Thomas Tallis was a very similar
experience to
a visit to the dentist - not actually painful but not
pleasant...

Are the original B139s worth selling on ebay to the
transmission line
enthusiasts?
They have a rubberized cloth surround rather than
neoprene
and lower
power handling
but otherwise similar specs.

B139s are very sellable. There are plenty of
transmission
line freaks
out there who love them. Just as well they haven't
discovered that
more modern speakers are even better suited to the job.
Or
that there
are much better ways to load speakers than transmission
lines.

Don't know about the tweeters though - they are probably
responsible
for the unpleasantness. They may be broken. The
Celestion
HF1300 was a
common match for the B139, and had a very smooth
response.


I would totally agree with that save that I still don't
think I have heard any speaker (save as said the R50, and
I
have both Spendor BCII's and KEF Q55's amongst others)
that
can handle the clarity, detail and natural sound of the
deep
bass - but I am willing to be corrected.

The other mod often made to the Bailey TLs was to fit a
Coles 4001G super tweeter which I found did help a tad
with
the realism of some instruments.

When the time difference has had its way I'm sure Trevor
Wilson will be along soon to give us the benefits of his
experience, and doubtless also some serious abuse and bad
language from Phil Allison! (They are box in Oz.)

The B139 has very nice sounding bass, but its woeful Xmax
(6mm) means
that it can't deliver loud bass.



Totally agree. But anyone who has been to a live concert -
be it orchestral, choral, instrumental, or organ - knows
that the sound is never as loud pro rata as people tend to
play it at home. A reasonable 'mid' volume with good dynamic
range beats sheer loudness in my book any day.

I think the B200 - and its look-alike the Dalesford - were
probably better for unmistakeable brute force!

You are right as long as the bass doesn't go very low. At it's
resonance of 28Hz it is protected by the coupled port from large
excursions, and it does very well. Much lower than that, though - a 64
foot organ pipe maybe, and it runs up against its end stops at very
low volume.

So don't play organ music through it!
