Kef 105/3 Reference Series Speakers; Black - Mint!

These classic speakers are in absolutely immaculate condition. These are coming from the original owner who had an entire system professionally installed 20 years ago. These speakers and all of the amplifiers and even the big screen television were built into the walls of the home so that everything was either hidden or flush with the wall. The system was a cost-no-object affair that was even featured in the pages of a AV magazine of the day. The speakers have literally been untouched since new. They were rarely used and are in perfect operational condition. Under very close examination, I can not see any cosmetic signs of use. They literally look brand new.

I am rating these as 8/10 only because of age. Includes a copy of the owner's manual. See photos for details.

Shipping for these will be by FedEx freight. We would never consider trying to box these for ground shipment - they are too big, too heavy and too valuable to subject them to that. We will carefully load them on a pallet and then protect them inside a custom "crate". We can ship them anywhere in the Continental USA for a flat rate of $199. Normal cost is usually more than this, but we will cover the difference to keep shipping affordable.

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.
