Loudspeakers

Oh to live in a trendy warehouse conversion overlooking the Thames. Imagine the acres of glass, the polished floors and the designer furniture with the Habitat labels peeled off. One’s loudspeakers would need to offer equally stunning visual splendour, exude an air of bespoke affluence and leave your friends (probably called Tarquin and Jemima) green with envy. Clearly you would need Jamo’s sumptuous R 909s or if your City bonus has been a little credit crunched this year, perhaps the smaller but equally lush R 907s reviewed here.

Perhaps because Audioplan is more than just a loudspeaker manufacturer – it makes cables, Sicomin isolation and damping products, and mains conditioners as well – the German company offers just three models of speaker. Each is a two-way design, although the costliest Konzert III incorporates three drivers: two forward-facing and a second bass-mid driver firing rearwards from the back of the cabinet. The bottom of the range Kontrapunkt IV B, on review here, has no such elaboration but still sports some unusual features. First of these to catch the eye is its – for want of a better term – cabinet stand.

The LS80 speakers by JBL are no shrinking violets, standing tall in the room at just over a metre high and weighing over 35kg each. The veneered sides are gently curved, as is the front. The wood finish for the side panels looks a bit dark for my taste and, as Henry Ford offered, there are lots of colours – provided you choose Dark Ebony, which is polished to a high gloss finish. The front, top and back are all in dark grey to black, so these speakers are quite sober in appearance.

Like Audio Physic’s Sitara model recently reviewed in these pages [see HFN June ’09], the latest incarnation of the Audio Physic Tempo – the sixth, no less – catches the eye by being notably slim, deep and tilted back at 7º to provide time alignment of its small midrange driver and soft-dome tweeter. As the grilles on either side of the cabinet hint, a pair of opposed bass drivers handle the low frequencies, an arrangement which facilitates the narrow front baffle and reduces vibration through cancellation of their magnet reaction forces. The only puzzle is why Audio Physic didn’t take the opportunity to mount the two bass units at the bottom of the cabinet, a disposition pioneered by Roy Allison to help reduce low frequency power output variations caused by interaction with the room boundaries. Its narrow footprint makes the Tempo cabinet relatively unstable, so Audio Physic provides aluminium outriggers which screw to the bottom of the cabinet to carry spikes outboard of the base at either side.

Along with the Spendor A6, Dynaudio’s Focus 220 – now in Mk II guise – is the most conservative looking speaker here. Whether you consider that a merit or demerit will depend on both your taste and your décor. Also like the Spendor it is a two-way, although in this case the soft dome tweeter is accompanied by twin bass-mid units operating in parallel. In common with all the other speakers here the 220 II is reflex loaded in the bass, with a port venting on the cabinet’s rear panel.

If you haven’t heard of PSB before it’s not because the company is a young one – it was established as long ago as 1972, when founder Paul Barton was still at high school. But PSB’s products, well respected in its native Canada and elsewhere in North America, are only now coming to our attention in the UK, with the Armour Group (responsible for NAD and many other brands) having been appointed UK distributor. As an emissary, the Synchrony One is impressive even given that it is the most expensive speaker in this test. Almost as tall as the Pioneer but broader, it also features five drivers but in a three-way configuration: a 25mm titanium dome tweeter, 102mm cone midrange and no fewer than three 165mm bass drivers (effective diameter about 153mm) positioned at the top, middle and bottom of the cabinet.

Vienna Acoustics was established in 1989 by Peter Gansterer in, believe it or not, Vienna. The city has some of the finest concert halls in the world, and may be considered as the birth-place of Classical (or Western Art) music. Peter lived in Vienna whilst studying acoustics… So no prizes for guessing how this ends up: a fine range of speakers named after classical composers, most of whom worked in Vienna. At the top of the Grand series is the Mahler, followed by the Beethoven Concert Grand, the Beethoven Baby Grand, the Mozart Grand and, finally, the Bach Grand.
