Loudspeakers

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.

These days we could probably name no more than 11 or 12 manufacturers of TVs, but ask us about loudspeakers and you'd fall asleep before we'd got as far as companies beginning with the letter 'D'. The industry appears to be in rude health, with models to suit all tastes and budgets, and there are plenty of options that you might not have come across before. Kroma Atelier's Stella Xtreme perhaps being one of them.

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.

Drop in on Derbyshire-based speaker company Living Voice at any hi-fi show, and it's hard not to be mesmerised by its Vox Olympian flagships. With styling somewhere between the brass section of an orchestra of several centuries ago, and a steam-powered Victorian imagination of a Dalek from Doctor Who, these £200,000+ models – £435,000 with the optional Vox Elysian subwoofers – are a riot of horns, tubes and 'trumpets'. Even in a high-end arena not known for its understated looks, they stand out. Moreover, once experienced, they are never forgotten.

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.

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.
