hfnoutstanding.pngKEF says 1000+ changes have gone into its new R Series, so how does this translate to the only standmount loudspeaker in the lineup? We listen to what the R3 has to say...

Who needs shifts in the weather when you can judge the time of year by hi-fi launches? Those of us who exist in the twilight world of hi-fi reviewing, and are strangers to Vitamin D, didn't need a chill in the air and the first signs of yellowed leaves swirling around to know it was autumn – instead, a flurry of press releases announced new or revamped speaker ranges, as the big names prepared for another season of long evenings and hunkered-down listening.

KEF’s statuesque Reference 5 embodies an overwhelming amount of research and development – it employs various techniques that are really quite new, but puts together many more that have emerged from earlier design work. The 125mm/25mm driver developed for this new range is the 11th generation of KEF’s Uni-Q designs, while the four 6. 5in bass units are placed as close as possible to this midrange/treble unit to minimise lobeing and interference dips at the crossover point. But rather than having a conventional cone, the bass diaphragm is a shallow aluminium disc, which gives the driver a lower profile and ensures a minimal effect on the frequency response of the midrange and tweeter.

hfnoutstandingIf there was anything wrong with the Kii Audio Three, it's fixable at a stroke by adding the BXT extension module

As the moving-coil loudspeaker approaches its centenary you could say plus ça change – much about it has changed, but some things remain stubbornly the same. For instance, for a large slice of the loudspeaker's lifetime, designers and enthusiasts have argued over how sound should be radiated into the room. Should a speaker 'beam' its sound towards the listener, thereby quelling the room's contribution as much as possible? Or should it fire sound in all directions, engaging the room as much as possible?

hfnoutstanding.pngIf the BeoLab 90 wowed you with its tech but daunted you with its size and price, here’s a pint-sized alternative

Kii Audio’s THREE is an exemplar of what can be achieved when the hi-fi industry’s, and hi-fi buyers’, lingering obsession with passive loudspeakers is set aside and a 21st century approach – active operation in conjunction with digital signal processing (DSP) – is adopted instead. In short order we’ve experienced the B&O BeoLab 90 [HFN Dec ’16], the KEF LS50 Wireless [HFN Oct ’17] and now the Kii (pronounced ‘key’) THREE.

hfncommendedWith a heritage that can be traced back over 60 years, and still now only in its fourth generation, the Heresy is manna from heaven for the nonconformist audiophile

American loudspeaker marque Klipsch has a longer history than many, something emphasised by its new 'p***ing off the neighbours since 1946' slogan. And its Heresy model itself dates back to 1957, when company founder Paul W Klipsch first developed a compact three-way floorstander to act as a centre speaker within a stereo installation. It has remained part of the Klipsch stable ever since, undergoing revisions first in 1985 and then 2006. Now it has been relaunched as the Heresy IV, priced £3500 per pair and forming the entry point to the Klipsch Heritage range.

hfnoutstandingProducing monumental SPLs from next-to-no-power, this refreshed American behemoth is no brick in the PA wall. Prepare to be stunned by the La Scala's scintillating sound...

Efficiency, sensitivity and coverage pattern – all attributes that are hard to beat,' says Klipsch's Principal Engineer Roy Delgado. 'The benefits of horn loading have not changed.' He's quite right, of course, but neither have the caveats, not least because attempts to deliver realistic bass typically requires gigantic horns and speakers the size of the average British garden shed.

hfnedchoiceRedesigned from the ground up, Klipsch's all-new Reference Premiere series leverages over 70 years of loudspeaker history. We audition the largest of its bookshelf trio...

With no shortage of standmount loudspeakers vying for our attention, any newcomer needs to stand out from the crowd. And few stand out as boldly as Klipsch's £625 'Reference Premiere' series RP-600M, arriving from a company with an auspicious portfolio of exciting-sounding horn-loaded loudspeakers [HFN Jun '19], all dating back to the first ever Klipschorn model launched in 1946.

hfnoutstandingArguably the most durable model in the Kudos catalogue, the C20 has witnessed a graceful 12-year evolution

As is so often the case, last time I was at a hi-fi show – c'mon, you remember shows – I was amused by the reaction of a visitor. Having listened to a fully active system using Naim electronics and a pair of Kudos Titan speakers, 'Hmmm,' he said to no-one in particular, and with deadpan seriousness, 'Not bad for a stand company…'. Well, stands may have been the beginnings of Kudos, but it's come a long way since then.

hfnoutstandingActive or passive? Exposure's new outboard crossover allows you to experience both with the Kudos Titan 707

As divisive audio issues go, few get the battle lines drawn more steadfastly than the matter of passive versus active loudspeakers. It's not so long ago that we were hearing about tiny monitor speakers with onboard amplification said to be good enough to have dyed-in-the-wool enthusiasts abandoning five-figure systems of conventional amps and speakers. Forget valves vs. solid state, or analogue vs. digital: when it comes to the topic of active speakers, tempers seem to flare among the keyboard warriors.

Not many audio companies, to my recollection, have made the transition from manufacturing speaker stands to making the boxes atop them, but that’s the journey undergone by Kudos Audio. Its stands are still winning awards but today the marque is as well known for the five-model range of Cardea loudspeakers, ranging from the compact C1 – joint winner of our group test last year (HFN Nov ’08) – to the recently introduced, top-of-the-range C30. Slotted beneath the latter and previous alpha male is the C20, a two-way floorstander that uses the same cabinet and bass-mid driver as the lesser C2 but is equipped with a superior SEAS Crescendo tweeter and higher-grade crossover components. Included in the latter are the bespoke silver-wired capacitors that also feature in the C10 – the cut-above version of the C1.

In 2012 Kudos introduced the £3500 Cardea Super 10 [HFN June ’12], a go-for-broke ‘supercharged’ version of the company’s 12 litre two-way standmount. Now the company has followed up with a ‘Super’ version of its Cardea C20 floorstander. Kudos has worked extensively with SEAS in developing specific drivers for its various speaker models, the Super 20 employing the 29mm ‘Crescendo K2’ soft dome tweeter first introduced in the £13,000 Kudos Titan T88 flagship. The bass/mid driver in the Super 20 is a newly-developed version of the SEAS 18cm unit with hand-treated paper cone.

Smallest of Leema Acoustics’ six-model speaker range, the Xero really is tiny at just 220x140x205mm (hwd), its front baffle having only about half the area of this magazine’s front cover. The moulding that houses the two pairs of input sockets for the split crossover occupies much of the rear panel, with just room for a small reflex port beneath, while the minuscule bass-mid driver at the front has an effective diameter of only about 80mm – little more than three inches. So this is a speaker for people with small listening rooms or who insist on their speakers having the smallest possible footprint. To this end the Xero can be wall mounted although for best sound its manufacturer rightly recommends using sturdy floor stands.

hfncommendedDesigned and handcrafted by the father and son team at Lu Kang Audio, the Spoey230 is the heavyweight flagship standmount of this artisan range from Taiwan's Taipei City

The last time you bought a television you probably came across no more than five or six different brands. But what about the last time you bought loudspeakers? It's one of the joyful aspects of hi-fi: the industry is very broad here, supporting a diverse range of manufacturers with different design ideals, resulting in an equally diverse choice for enthusiasts.

The use of ceramic materials in loudspeaker diaphragms can’t be described as novel because every anodised aluminium cone or dome has a surface layer of alumina (aluminium oxide), allowing it to be described as a ceramic-metal sandwich or similar – as at least one speaker manufacturer has indeed done. But pure ceramic diaphragms are a rarity, and loudspeakers that use them exclusively, as the Lumen White Silver Flame does, are rarer still. All five drivers in this arresting-looking three-way design have white ceramic diaphragms in the form of everted (concave) domes. As explained in the box-out, the attraction of a ceramic diaphragm material is that it can be lighter and stiffer than common metal equivalents, which promises higher bending wave velocity and hence higher breakup frequency for a given diaphragm size and shape.

hfnvintageMartin Colloms hears KEF's no-holds-barred flagship speaker, the R109

In late 1995 an idea began to take shape at KEF Audio. The company had already produced some fair-sized 'reference' models, culminating in the well-regarded Reference Four. But even this powerful and accomplished design lacked the necessary weight and presence to make a major impact at the highest quality level of world loudspeaker sales. So research began to define the key elements of what was intended to be a much larger speaker system, a definitive engineering expression of the company's knowledge.
