Summary:

When I bought my KEF 107 back in 1987 in England I felt great, as the most important part of my system was brought bck to Athens in Greece.
Speakerwise to my liking there was a thin line betwwen KEF and IMF with the later using KEF's drivers. Great speakers too, but very difficult to place and stricktly monitors. My vote went for KEF.
To mate these speakers you need at least 300 watts at 4ohms. Once you tackle this problem then you've crossed the muddy river! Don't bother with the KUBE it just pusts a veil around the beautiful sound these speakers produce. Another trick is to use top gear in order to fully exploit the potential of these long gone wonders of speakers. You do that and then you'll come to realize that speakers close to their sound would cost you a pretty penny say over 30.. smackers!
My system consists of : Pluto turntable 12R,pluto arm special 5A with a Koetsu Urushi cartridge,cd player:cd7reference by Audio ResearchTape:Dragon Nachamishi. Mark Levinson 25 Phono stage.Mark Levinson 26 Preamp.Mark Levinson 23.5 amp. The entire system is cabled by NBS master series. Power conditiner: TICE block III Singature Series.

Strengths:
I woud say the bass wich goes down to almost below 20 Hertz! I have tested those twin 10 inches woofers with every possibe test cd from Stereofile test cd's to perhaps the best one by Granite Audio. They're just amazing.
Midrange is equally good all the way to the top when the paper tweeter takes over!
If you could get hold of some Tomas Koner and Jascha Heifetz cd's then you'll see my point.

Weaknesses:
None

Summary:
I have been looking for these speakers for almost ten years, and when I finally found a pair in mint condition, the desicion was easy! My system is: meridian 501 pre, 504 tuner, 508 ca and 2 meridian 605 monoblocks. After a few seconds, I realized that I am never going to let these speakers go! The bass is DEEP with 100% control, even on very loud passages. The dynamics are excellent, even at low level. The midrange is smooth as silk, and makes female voices sound very lifelike. And the treble sounds like ripples in a clear mountain lake! Although they are quite big and heavy, they look good in my medium-sized livingroom. They are quite a difficult load for the amplifier, so make sure that you have enough power! I'm dreaming of a surround-system with 3 pairs of 107/2, so if anyone's selling, I'm buying!

Strengths:
Bass, overall sound, dynamics, looks. Everything!

Weaknesses:
None

Summary:
When I acquired the 107.2's without the matching KUBE bass equalizer, I felt that the bass was weak and I really had to look for that KUBE to maximize their potential as full-bodied speakers. The 107's then were driven by a combination of Audio Research SP9 MK2 preamp and Quicksilver 8417 monoamps and Rotel 1072 cd player. While in search of the KUBE, I tried biamping using the 60wpc tubed monoamps on the mid/high and a Quad 606 amp on the low frequencies. With this set up, I noted an improvement on the bass output that is deep, tuneful and adequately complimenting the mids and the highs. For now, I'm holding on this pair of audio masterpiece that is an all around performer, be it classical, rock or jazz. Biamping is an option that does away with the KUBE and rewards the listener with a well-balanced sound that comes close to the original.

Summary:
Suprised to find no reviews for kef r105/4 loudspeakers. Anyone know of these ? Head assembly like the kef r107 T33 treble b110 mid two forward facing 8" drivers in the lower cab , protection s stop ect. I used a pair of these before purchasing kef r107 , still using the 105/4 in my second system , superb little speaker though protection i found intrusive , operating when using high power amps ect . I also found that the imaging and soundstaging of these speakers improved substantialy when they were rewired with audioquest cable , and fitting a concrete base improved the bottom end . Seems like another overlooked superb kef product .

Strengths:
Superb punch and drive , Imaging,soundstage depth n width. Brilliant head assembly.

Weaknesses:
Internal wiring as all early KEF, Intrusive protection circuit, Castors , remove and fit spikes. Head assembly ,as all kef ref ,could be more innert,with a more secure spigot arangement.

Summary:
I use KEF R107 MK1 rewired with chord cable , no kube as I found this curtailed treble detail and added hiss , I thoroughly recomend rewiring the speakers if possible , can also benefit by being bolted to a granite or similar slab , improving bass definition , imaging , depth , detail ect . I bought these to replace a pair of KEF R105/4 loudspeakers which had been heavily modified by removing the protection circuits , fitting a concrete base and rewiring with audioquest cable , These were exceptionaly good loudspeakers , but I was completly floored by the demo given with the KEF R 107 , the walls and ceiling melted away , the bottom end was frightening , dynamics stunning , a soundstage that completly surounded me . Sadly though I lost a lot of the speakers performance when I moved to my present location , these speakers revel in a good large solid enviroment , concrete floors and ceiling with brick and plaster walls , plaster board and suspended floors do them no justice . I still enjoy using these speakers ,though the treble and mid are slightly lacking by todays standards they bring a wholeness to music , an almost organic quality that brings performances to life . I find these speakers to be extremly revealing of amplifier performance , if there is hiss or hum from your amp these may highlight this , I loved the musical fidelity Nu Vista 300 power amp through these but couldnt live with the valve noise , same with a bat VK3I pre amp I used . I think a Tact Audio 2.2 or Music First Passive would do wonders ? Time to start saving again .....

Strengths:
Constantly show improvements with equipment upgrades , stage depth , bass , full range , child proof .

Weaknesses:
Dont quite disapear like Martin Logans or the 105/4 , bottom end and room placement can be tricky , treble and mid performance .
