11 of the best KEF products of all time

11 of the best KEF products of all time

KEF is one of the most well-respected British brands in world hi-fi and has been for well over 50 years.

The company’s ethos is based around engineering, design and development which can be seen in trademark technology such as the Uni-Q driver, which still features heavily in its products today.

In recent years the brand hasn’t been afraid to diversify, either, and now covers a wide range of categories, from stereo speakers to custom installation solutions to headphones, wireless speakers and all-in-one streaming systems.

To celebrate British Hi-Fi Week, we’ve rounded-up 11 of the best KEF products to pass through our test rooms since the birth of What Hi-Fi? In 1976. So kick back, relax and reminisce.

KEF Coda III (1985)

KEF Coda III

The oldest model on this list, the KEF Coda 3s originally featured in What Hi-Fi? way back in 1985. At just £99, the Codas were a serious bargain and although they didn’t feature KEF’s trademark Uni-Q driver, they still managed to impress. We noted their “excellent stereo imagery” and “clean, controlled and well-extended bass”, as well as their tendency to sound “slightly dry and splashy” with “high level rock”. The Coda IIIs used a KEF designed and Japanese built 3cm fabric dome tweeter, plus a 20cm paper pulp mid-bass driver which was glued into the cabinet to ensure a solid seal. Proper budget speakers didn't get much better in 1985.

KEF 105/3 (1990)

KEF 105/3

The 105/3s (pictured above, middle) were clever speakers that combined a couple of different KEF technologies. The company's trademark Uni-Q driver was present, but it was also joined by what KEF referred to as its coupled-cavity bass loading tech, which had two drive units actually firing within the speaker’s cabinet. Bass frequencies would then emit from a solitary opening on the front of each speaker. This was done to lower distortion, improve power handling and deliver more bass from a small cabinet. The speakers served a solid, tangible soundstage and rich, textured bass.

KEF Coda 7 (1995)

KEF Coda 7

In the mid 1990s, the sub-£150 speaker market place was a tough place to be. Mission had a stranglehold and were proving difficult to beat. Enter the Coda 7s, KEF’s brave attempt to wrestle back some of that market share. Their 30cm cabinets used an upside-down driver layout with a 13cm coated paper bass driver sat above a 25mm soft dome tweeter. Not the most high-tech design, then, but they still managed to produce an outstanding sound. At the time we said the KEFs “not only throw down the gauntlet to the likes of the Mission 732s, they cock a snook and thumb their nose too!” High praise indeed.

KEF Q35 (1997)

KEF Q35

Small and compact floorstanders have a certain charm and this was definitely the case with the diminutive KEF Q35s, which debuted in 1997. They weren’t keen on being cranked to the max, but if the quality of your recordings was up to scratch, the KEFs were capable of delivering one of the most realistic sonic experiences available at their £349 price point. We described the quality of their imaging as “almost eerie”, and able to “give a three-dimensional, almost tactile effect”. We also strongly advised that you listen to them bi-wired, which we found only further enhanced their resolution, which was “unrivalled at the price”.

KEF Cresta 2 (1999)

KEF Cresta 2

The Coda 7s were always going to be a tough act to follow, but KEF managed to maintain its lofty standards with the arrival of its new Cresta 2 standmounters. At 37cm they were relatively tall for budget standmounters and this extra size was reflected in the exceptional sense of scale and openness. Like the Coda 7s, the Cresta 2s used a simple 25mm soft dome tweeter with a 13cm coated paper cone, but in a more traditional arrangement, with the former positioned above the latter. Tonal evenness and subtlety weren’t their forte, but it was the stunning musicality that won us over.

KEF KHT2005 (2001)

KEF KHT2005

If you want a home cinema icon, then look no further than the KHT2005 from 2001. Affectionately known as the KEF ‘eggs’, this sub/sat system offered not only performance in spades, but a serious dose of style too. The cast aluminium, egg-shaped satellites looked the business and were a welcome distraction from more traditional-looking boxy alternatives. Together with the system’s 150W subwoofer, they combined to produce an exciting, entertaining and cohesive surround sound experience that entertained us for many a year.

KEF Reference Model 203 (2001)

KEF Reference Model 203

KEF completely revamped its flagship Reference range of loudspeakers in 2001. The Reference 3s were four-way baby towers that boasted beautiful curved cabinets, and a time-aligned tweeter sat on top of a Uni-Q driver. The configuration of the speaker meant KEF had five separate drivers to integrate, yet the 203s still managed to produce a “beautifully seamless” sense of cohesion across the board. We said the speakers delivered a “dynamic, exciting performance that gives a crystal-clear view of the music.” Even at £3000 we felt they were worth every penny.

KEF iQ5SE (2007)

KEF iQ5SE

The Q35s evolved over the years and 2007 saw the launch of the iQ5SE variant, which battled it out with the truly exceptional Monitor Audio BR5 and B&W 685 speakers. Like its ancestors, the iQ35SEs were a compact and attractive pair of hugely talented floorstanders. The speakers majored in speed and punch and combined this impressive rhythmic accuracy withn excellent dynamics and stereo imaging, even if they couldn’t quite knock the B&Ws off the top spot.

KEF LS50 (2013)

KEF LS50

In 2013, to mark KEF’s 50th anniversary, the company celebrated by launching the £800 LS50 standmounters. They weren’t a high-end, mega-money pair of loudspeakers, but they still made quite the impression, blowing the competition out of the water and receiving a glowing five-star review for their troubles. The LS50s boasted striking looks and saw KEF use a new DMC (Dough Moulding Compound) material for their curved front panels. They also featured unusually flexible bass reflex ports designed to reduce unwanted midrange distortions. Needless to say the LS50s sounded exceptional, with impressive dispersion, a huge stereo image and big, communicative bass.

KEF Reference 1 (2018)

KEF Reference 1

The price tag might be £5k but the Reference 1s are worth every penny – you won't find a better bookshelf speaker in KEF's entire stable. They're a shining (and shiny) example of KEF's high-end engineering at its best, and set a benchmark that few rivals can match. They look stunning in the flesh, with beautifully finished cabinets that you bolt onto KEF’s matching stands. A simply gorgeous speaker with the sound to match, the Reference 1 speakers are brilliant all-rounders that work superbly across across a wide range of music, systems and rooms.

KEF R3 (2018)

KEF R3

You don’t have to trawl back very far through the What Hi-Fi? Archive to find the KEF R3s. They’re on page 62 of our 2018 Awards issue, complete with the stereo speaker Product of the Year stamp of approval. Such an accolade doesn’t get handed out to any old pair of speakers so you’d be right to assume the R3s are something special. We noted “a level of insight and detail resolution way beyond most rivals” and the fact they deliver "a sound good enough to worry most speakers below the two grand mark". The KEF R3s are the complete package and one of the most talented all-rounders we’ve heard from the brand in recent years. And a fitting end to our round-up.
