Loudspeakers

Still going strong after 20 years, the Venus is nothing if not the ambassador for the room-friendly 'omni'

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.

The updates to this long running range have proved particularly effective Dynaudio’s Focus range was getting a bit long in the tooth so we weren’t surprised to learn when we requested the 140 for this test that it had just been replaced with this new model, the 160. Little has changed externally – if you’re the type who can distinguish Aston Martins at a glance then you’ll note a new light grey paint finish on the drivers and the use of Torx fasteners, only three of which now attach the tweeter – but internally there’s more that’s been breathed on. As before, the cabinet side walls taper a little towards the rear from the narrow bevels at the front baffle edges – a feature which helps tame internal standing waves – but the enclosure has been significantly stiffened. The 170mm bass-mid driver retains its magnesium silicate polymer (MSP) cone, and the voice coil is still aluminium to reduce moving mass.

With a coincident driver array and interport-coupled cavity bass, meet the company’s most radical floorstander in years

Out with the old and in with the new. ELAC is a German loudspeaker company of quite some repute and a great many years’ standing. Yet major changes have been afoot at the company, with its new VP of Engineering, Andrew Jones, indelibly stamping himself on the brand’s products. A former KEF man – there in what were arguably the company’s harvest years with Laurie Fincham, in the late 1980s – he went on to put Pioneer’s luxury brand TAD on the map with some great soundinghigh-end loudspeakers [HFN Jan ’15].

Featuring a concentric mid/treble driver with a difference, ELAC's Concentro range goes 'compact' with the S 503

For those who felt that ELAC wasn't one for adventurous industrial design, the Concentro series has proved them wrong. You'll find some very curvy and organic-looking models in this range, which rises even above the finely crafted and attractive Vela series [HFN Apr '19]. However, the Concentro range still feels more like a disparate collection rather than a real product family. Virtually every model has its own design, from the menhir-like Concentro and Concentro M to the high-heeled S 507 and S 509 floorstanders.

This tall floorstander takes its place as the top model in Elac’s Line 400 series. All use the JET 5 tweeter, Elac’s development of a concept patented by Dr Oskar Heil called the Air Motion Transformer (AMT). In the Heil AMT, the moving element is a very light plastic membrane that carries a fine metal track to conduct the audio signal. Suspended between powerful magnets, this membrane moves when current flows.

The new ELAC Navis 'powered speaker' series is a slick system alternative, whether or not you use it wirelessly

As one of the largest-scale speaker manufacturers around, US/German company ELAC has what can sometimes seem like a baffling range, all the way from very affordable mini-monitors and 'subwoofer and satellites' packages right the way up to very high-end floorstanding designs. And apart from the sheer breadth of the lineup, this diversity allows it to explore a variety of technologies: in this range there's no signs of a 'one design fits all, just in different scales' approach.
