Despite the small size, this well thought out design has much to commend it As the smallest and lightest speaker here, the Synchrony Two B may seem to be flying a kite in asking £1200 of its buyer. And, indeed, it is significantly cheaper in its native North America. But remember that its sibling, the large, floorstanding Synchrony One, won our group test in Aug ’09 – and take a look at the lab report. It may be diminutive but the Synchrony Two B walks tall: it has one of the flattest on-axis frequency responses here and a waterfall plot so clean that few more overtly prestigious speakers can match it.

Some very sophisticated technology doesn't quite come together as a cohesive whole In loudspeaker cabinet construction, curves are good. Curved panels are stiffer than equivalent flat ones – but more difficult to make than the V-groove and wrap box construction that so many speakers today employ. In creating what is the most expensive model in this month’s group, Mordaunt-Short clearly devoted a good deal of its budget to abandoning the traditional rectangular wooden cabinet in favour of a curvaceous enclosure moulded from a well damped polymer resin. Deeper at the bottom than at the top, in profile it looks positively Falstaffian.

The high-end hi-fi industry is perhaps unique – certainly unusual – in that it continually holds the present to account, against its past. Many audiophiles, often not with nostalgia foremost among their motivations, wilfully divest themselves of the ‘benefi ts’ of modern technology, preferring vinyl to digital, vacuum electronics to solid state and full-range drive units to the meticulously developed multidriver speakers that purport to represent the state of the art. If we think of this as a spectrum of design approaches rather than Montagues versus Capulets, the Aurousal VSx – the new, improved version of the VS that won our group test in HFN Aug ’10 – is certainly not at the extreme occupied by single-ended triodes and re-entrant horns. Although the VSx does turn the clock backwards somewhat: in eschewing multiple drivers knitted together with a crossover network in favour of a pair of full-range drivers supplemented by a dome tweeter.

Forming an enclosure from glass is a costly process. So Waterfall’s floorstander represents fine value with style Peceived wisdom generally has it that a loudspeaker’s enclosure should be inert, so that we hear the acoustic output of the speaker’s transducers unsullied by the additional singing along of a cabinet. As ever in our wonderful world of sound reproduction there are designers who refute this given ideal. The late American speaker maestro Peter Snell, for example, whose Snell Type J and Type E models from the 1970s live on in the guise of today’s UK-made Audio Note speakers.

It might look like more of the same, yet this Q series loudspeaker boasts some new features at front and back The Q900 may be top of KEF’s brand, spanking new Q series – the meat and potatoes of its range – but to look at, inside and out, it appears in some ways to represent a step backwards, certainly in respect of KEF’s rich technological history. The Q900 effectively replaces the previous iQ90, a speaker which bowled me over when winning a group test just over a year ago [HFN Mar ’10]. One of the notable aspects of the iQ90 was its curved cabinet, a feature of more than aesthetic significance since it stiffens the enclosure, whereas the large side panels of a conventional box cabinet are prone to resonance. It was a surprise, then, to find the Q900 has what KEF rather grandly terms a ‘rectilinear’ cabinet – what you and I would call a standard, slab-sided box.

After a long absence, Magnepan's iconic 'room screen' panel speakers are finally back in the UK Firsts linger long in the memory. That first school, first car, first kiss. . .
