Kef 101's VS LS3/5A
Kelly
and the LS3/5A's.?
Don't most LS3/5A speakers use Kef drivers, and aren't the dimensions
very close? Are the Kef 101's concidered to be good speakers?
Anyone who's had or has the Kef 101's like the sound from them?
Thanks

Many iterations of the LS3/5A use KEF drivers, but not all. The
dimensions are close, but not identical.

I've repaired a couple, and owned a pair for a while. It is a sealed
box monitor of relatively low efficiency, with smooth response, but
fairly low power handling capability. In addition, the woofer has a
fairly high mass, which to some results in bass that lags a bit. The
parts quality, both drivers and crossover, is excellent, however, as
is the cabinet. You should try listening to a pair if you get the
chance, before making a decision.

I like both and currently use a pair of LS3/5A's; these are musical,
involving, exceptionally nice sounding little speakers with the right
music (vocals, acoustic piano, guitar) and the right amp (ARC Classic
60), when used within their design limitations. The KEF 101's are
probably more accurate, with flatter response and more extended bass
and highs. Both designs use the same tweeter and bass driver, but
the crossovers and enclosures are different. Both are good quality
designs, both produce good sound, both are good values.

I love my old KEF 101s -- no bass to speak of, of course, but love
the imaging. I think I paid around $600 for them back in the late
'70s/early '80s (can't quite remember), got the ones with the cherry
cabinets. They were certainly hot-stuff at the time, though I don't
know how they stack up with today's technology. Took em off to
college and through multiple moves over the past 15 or so years and I
still like them a lot.

This is absolutely NOT true.
The LS3/5a was designed as a near-field monitor for use in the field
by BBC engineers. It was and is one of the (perhaps THE) tightest
specified speakers ever to see mass-production. Except for minor
adjustments along the way (one major mentioned below) they have
remained in production essentially as designed for longer than any
other speaker I know of.
The LS3/5a has ALWAYS used KEF units which were VERY close to
production versions of the B110 bass-mid and the T27 tweeter. They
had different labels for the LS3/5a production because these were far
more closely specified than normal production spread of tolerances.
BBC did not wish to enter into loudspeaker production so they made the
design available for licensing allowing a number of speaker
manufacturers to build the LS3/5a over the years. The reason (at
least one of them) the specifications were so strict was that BBC
wanted to be able to take any two speakers from a shelf and still have
a balanced stereo pair. So in production each pair had to be tested
to the quite stringent specifications otherwise the manufacturer would
quite quickly lose the license.
Manufacturers included Spendor, Chartwell, most well known Rogers and
finally after a good many years KEF.
For many years the speaker was a nominal 15ohms speaker through the
use of an autotransformer. This was changed (I think when KEF entered
into production) to a nominal 8ohm load. Of course this was approved
by the BBC. Another design modification included at this point was
bi-wiring ability.
A good many speaker designs owing much to the LS3/5a have been put
into production over the years, some of them very good indeed, but
none of them will ever have the longevity and fame of the LS3/5a.
I took out my 20 year old Rogers the other day for a spin and while
you can certain pick some nits (the somewhat spitty treble and the
famous 130Hz bump) they remain a very impressive design after over 25
years in production.
