KEF Reference Series Model 107 Vintage Speakers, Fully Restored

$1,699

In the mid-1990's, the KEF 107's and the B&W Matrix 801's were THE speakers to have - if you could afford them!

They both had a similar layout with larger cabinets at the bottom leading to smaller cabinets at the top, thus creating the necessary time alignment.  They differed mostly on how the bass was produced.  While the 801's relied on a single large woofer, KEF chose a more technically sophisticated approach utilizing dual isobaric woofers housed in an internal chamber. 

This allowed for a slimmer lower cabinet and a far better looking speaker, without compromising the low frequency performance. 

We're big fans of both speakers, and thankfully we don't have to chose as we often have both sets in stock to play with. 

This particular sample came to us from a collector that took great care of them.  The woofers on these KEF's usually suffer from rotting of the surround material, as back in the 90's they didn't really know how to make foam surrounds last for eternity.  This set had the woofer surrounds replaced professionally (both surrounds and annulus), and are in perfect working condition.  The tweeters and mids are also in perfect working condition and output evenly and precisely.  The cabinets show a bit of wear but nothing too noticeable.  

Sound quality is superb with a tinge of vintage sound, while still being able to provide the dynamics of a modern speaker. 

Really no compromises are evident unlike some other vintage speakers from this era.  

More details from the KEF Museum website:

"This innovative model provided quite outstanding performance with an unusually high degree of user convenience. This was achieved by combining many of the tried and tested Reference Series features with a new concept in active low-level equalisation, KUBE (KEF Universal Bass Equaliser). The result was a unique combination bass extension down to a genuine 20Hz, and good sensitivity, from a surprisingly compact system which is sonically flexible enough to be tailored to its specific surroundings.

Model 107 combined the separate mid/treble enclosure from the 105/2 with the coupled cavity bass loading technique developed for the 104/2 and established itself as one of the world’s finest loudspeakers. The midrange driver was a new polypropylene-coned B110 allowing higher sensitivity with improved strength and durability. As with the 102 and 103/3 the KUBE was an integral part of this system and essential in obtaining its specified performance."
