Loudspeakers

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?

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.

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.
