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.
