Made In England
Model 105/3 was the first Reference Series loudspeaker to incorporate Uni-Q technology.
It was a four-way system, employing six drive units, with very high sensitivity, high output capability and outstanding power handling capacity.
Several design features of the 105/3 were directly derived from the acclaimed Model 104/2. Bass reproduction was handled by development of the 104/2’s coupled cavity system, and the separate midrange enclosure module was also retained and developed – this time to incorporate two dedicated lower midrange drive units and the new Uni-Q upper midrange/tweeter driver array.
Consistent with other the Reference Series loudspeakers, Model 105/3 included conjugate load matching to improve the amplifier-speaker interface and performance was enhanced with the use of the KUBE 200 active equaliser. In the case of Model 105/3 and the Reference Series systems that followed, the use of the matching KUBE was not essential, the loudspeakers were optimised to function in standard passive configuration.
The addition of Uni-Q coincident source technology allowed a major improvement in directivity control, in particular, the removal of the constrained vertical directivity of convention loudspeakers caused by the vertically separated midrange and high frequency drive units.

Review for reference :
After long and painful process of searching the right set of speakers, Kef 105/3 was my final destination. Different people have different preferences, but Kef 105/3 is the answer for those who are willing to listen to music, rather than the sound.
I don't think, dynamic, speed, openness is the word to describe these masterpiece, so if these are the things you are looking for, please look elsewhere.
Also, as other reviews have recommended, this 93db speaker is my no means an easy piece to drive its full potential. Don't be fulled by its spec and the used price. They deserve much more than what is normally expected.
I run them with famous Mark Levinson 23.5 and 26s combination. Mark Levinson ML2 was the reference amp they used to design 105/3 at the first place, so there is little issue with the matching.
For those who are using the 105/3 I recommend Mark Levinson Amps from the similar time period, like ML 2X series(20.6, 23, 23.5, 27, 29 etc), and you will experience true sound of the Kef 105/3 which people often describe as "deep and strong espresso"
totally tonality, vocals specially women sounds unbelievable, Bass reproduction is so accurate that you wonder yourself of the variety. Never loosing the overview , no lack of sound levels . they are very sensitive
