Loudspeakers

When the entry-level model in a speaker range costs £70,000 a pair, and weighs no less than 80kg – that's each speaker – you'd rightly assume you're in very serious high-end territory. And yes, imposing though the Prana speaker looks, its two aluminium enclosures mounted on a hefty 'Z-frame' and the whole enterprise standing some 99cm tall, this is the baby of this particular range. Above it sit the Satya speakers, 1.23m tall, 140kg apiece and £110,000 a pair, while the flagship is the 1.47m tall, 180kg-a-pop Samadhi, yours for a nice neat £200k a pair...

We've been here before, reviewing the Scansonic MB5 speakers three years ago [HFN Aug '17]. However, collective amnesia has not set in, for despite the £6249 MB5 B looking near enough identical in its choice of black or white silk finishes, it is in fact a new version of the design, reworked by chief designer Benno Baun Meldgård. Hence the 'B' suffix on the new model.

Constant change is here to stay' as the saying goes. And it's certainly true of ELAC – one of Germany's most long-established hi-fi manufacturers – as the brand has spread its wings over the past few years. ELAC began life way back in 1926 in the coastal town of Kiel, where its main focus concerned the development of sonar systems. It was after the Second World War that it began manufacturing turntables and pick-ups.

Time waits for no one – especially if you're a speaker manufacturer. Focal knows this, and will regularly refresh its ranges to maintain its competitiveness. That said, the popular entry-level Chorus lineup [HFN Jun '08] has held sway for longer and only now is it superseded by the high-value Chora range.

Mention 'omnidirectional' and most worldly-wise audiophiles will remember seeing MBL's remarkable Radialstrahler loudspeakers at one hi-fi show or another. Once seen and heard they are not easily forgotten, but they are also devastatingly expensive! By the same token, affordable omnidirectional speakers have never quite made it into the mainstream of hi-fi despite Sonab being a major player back in the 1970s and Canon's models from the 1980s also finding favour with many listeners.

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.

Of late we've had some speakers through editor PM's listening room only describable as imposing, but nothing quite prepares one for the sheer visual impact of the Duo Primo XDs from Germany's Avantgarde Acoustics. Standing some 1.8m tall by 67cm wide, and weighing 185kg apiece, installing them is a matter of slotting the boxes together rather in the manner of building a PA stack – an appropriate analogy, as we'll discover – while the price-tag is similarly huge, at £79,500 a pair.
