PMC GB1i Transmission line bass loading distinguishes this compact floorstander from most of the competition Since its beginnings in the late 1980s, PMC has grown into a major player on the UK speaker scene, focusing on ProAudio customers and the more upmarket hi-fi sector with its ATL (advanced transmission line) speaker systems. Although it’s no larger in width and depth, the £1,525 per pair GB1i is a little taller than the other two-way models that use small bass/mid drivers. The reason has all to do with the transmission line bass loading technique, which squeezes a carefully damped 2. 4m line into the enclosure volume behind the main driver, by folding it twice and terminating it with a large port at the front near the floor.

ProAc Studio 140 Mk2 Substantial floorstander’s twin 165mm bass/mid drivers ensure a very muscular performance with superb headroom array A long-established British speaker brand with roots back in the 1970s, ProAc has only made the occasional appearance on the Hi-Fi Choice review roster. That’s mainly because the company has long been primarily export-oriented, with representation in more than 50 countries worldwide. The three Studio models – two standmounts and this floorstander – are among ProAc’s less costly models and although this Studio 140 Mk2 pricetag of £1,690 per pair is at the top end of our test group, the speakers themselves are as large as any of the others, as well as the heaviest in the group. The dimensions are partly dictated by the twin 165mm drive units that operate in tandem right through the bass and midrange here.

Rega RS7 Rega’s RS7 combines several new developments, in both its tweeter design and its bass loading The RS7 sits at the top end of Rega’s loudspeaker range. First reviewed in these pages during 2009 (HFC 322), the price per pair has increased since then from £1,469 to £1,685 (partly thanks to VAT changes) for the regular cherry or black wood-veneered versions; high-gloss black or white are also available at extra cost. The front view of the sharp-edged enclosure is exceptionally slim, but the RS7 is also unusually deep and quite tall. Fore’n’aft stability is inherently excellent, while moulded outriggers improve the lateral stability and provide reasonably secure spike fixing, though the thumbwheel lock-nuts unfortunately loosen rather readily.

Spendor A3 Spendor’s new compact floorstander has much in common with the company’s successful SA1 baby Spendor’s baby SA1 sub-miniature has already proved quite a hit, commercially and critically (Group Test Winner HFC 334), so it’s hardly surprising that the company should use some of its elements as the basis for this very compact floorstander. There’s much more to it, of course, than simply transposing drivers and crossover network into a larger box. Although the tweeter is the same for both models – the unusual wide-surround unit that Spendor now favours for most of its models – and the bass/mid driver is built on the same chassis, there are substantial changes elsewhere. The very compact, sharp-edged enclosure is set low, with the drivers comfortably below seated-ear height, but the optimum listening axis is deliberately arranged to fire slightly above the horizontal to compensate.

Power towers Roth Audio has moved into loudspeakers. Ed Selley gets to grips with the flagship model from the new Oli range, complete with ribbon tweeter Roth is a youngster in audio terms. From its founding in 2007, the company has produced a wide range of iPod ancillaries and lifestyle products, and has now moved into loudspeakers. The five- strong OLi range has two bookshelf speakers and three floorstanders, the largest of which, the £800 OLi 50, is tested here.

Epic performer The new Epic 5 looks more than a little like Epos models of old and as Ed Selley discovers, it’s a return to form for the much-admired brand Back in the early 1990’s Epos did rather well out of its ES range of loudspeakers. Well thought out and well designed, the ES models were distinctively finished with a wood cabinet and black front panel. Nearly twenty years later the Epic 5, tested here, has more than a little of the ES models in its aesthetic. Like other examples of the current trend for revisiting past designs, the Epic 5 is very much of the moment, internally.

Join the Revolution This brand new member of the Revolution series looks like much better value than its Signature equivalent says Paul Messenger The Revolution DC6T is an impressive newcomer dual-concentric full- range driver, with a 150mm bass-only unit (similar in specs to its sister product, the Signature DC6T, that we reviewed in HFC 314). All this is contained within a compact 30-litre, rear-ported enclosure and the detailing throughout is excellent. The enclosure is tapered so that the back is significantly narrower than the front, helping to spread and distribute internal reflections and standing waves. All this is elegantly wrapped in an attractive dark ‘espresso’ real wood veneer and the overall stability of this model is substantially enhanced by the provision of a black plinth, which significantly increases the footprint.

Fine Dyning Danish-made with in-house drive units, the DM3/7 is one of a dying breed of well-priced 'homemade' speakers says Paul Messenger One of several ranges from this upmarket speaker brand, the ‘plain-Jane’ DM-series loudspeakers are primarily intended to combine Dynaudio’s core technologies within cost-effective suits of clothes. The DM3/7 is certainly no exception, being a straight two-way that combines two 170mm bass/mid drivers operating in parallel and a 28mm doped fabric dome tweeter inside a decidedly plain and understated enclosure. But while the DM3/7 won’t stand out in any fashion parade, it does look neat enough in its own understated way and also incorporates much of the fundamental engineering content found in the company’s more costly models. The DM3/7 is actually the latest of a DM-series that currently comprises three stereo pairs and a centre-front AV model.

Bronze Age High-performance speakers needn’t cost the earth – Ed Selley listens in on the latest evolution of the popular Monitor Audio Bronze Series Monitor Audio has been producing the Bronze series, its entry-level full-size speaker range, for some years now. And the latest update takes the line-up from BR to BX status and features a full choice of standmounts, floorstanders and supporting multichannel equipment. Design refinements include single- bolt driver fixings and HiVE reflex ports borrowed from the more expensive ranges. The £500 BX5 tested here, however, is the smaller of two floorstanding models.

Life partner Audiovector’s 'upgradable' speakers can be improved when funds allow. Paul Messenger investigates a unique proposition from Denmark The Ki-series is relatively new and also relatively inexpensive by Audiovector’s standards. The Ki 3s are the sole floorstanding models in a range that also includes a standmount and home cinema oriented variations. But each Ki-series model comes in three versions – Standard, Super and Signature – with superior engineering features as one moves up the ladder.

Dynaudio Contour S 1. 4 Dynaudio is one of very few overseas brands to become properly established in the UK Based in Denmark and owned by a German, Dynaudio’s particular approach to loudspeaker design has been much more successful at achieving a significant presence on the UK market than most overseas brands. That probably owes much to the company’s distinctive proprietary technology and a consistency in approach which has helped it become well accepted by both hi-fi consumers and ProAudio users alike. Contour ranges have occupied Dynaudio’s middle ground for many years.

Monitor Audio Platinum 100 This baby model in Monitor Audio’s gorgeous Platinum ‘flagship’ range features a ribbon tweeter Founded in 1972, Monitor Audio now qualifies as one of Britain’s longest established speaker brands, especially amongst those still in UK ownership. Although it’s best known for successful ‘mainstream’ models like the Bronze and Silver series, the company took a significant step towards the high end in 2007, with the introduction of Platinum models like this £2,500 per pair Platinum 100 two-way standmount. A ribbon tweeter is the hallmark of all the Platinums and here it’s combined with a 165mm bass/mid driver in an exceptionally solid and beautifully finished enclosure with a decidedly complex shape. The back and sides are formed as a continuous curve, with mildly convex sides, a slightly concave back and quite gently curved edges.

Opera Callas This very compact and exquisitely presented stand-mount has a thoroughly unconventional multi-tweeter Opera and its associated electronics brand Unison Research both share premises near Treviso in north east Italy. And in the best Italian tradition, this standmount looks absolutely gorgeous and is very substantially built too, though it’s not exactly cheap at £2,875 per pair. A solitary and rather small 135mm driver with a 100mm diameter magnesium alloy cone covers the bass and midrange. It has a large (38mm) fixed solid copper ‘bullet’ phase plug and is assisted by reflex loading from twin rear ports.

Spendor SP2/3R2 This speaker might look old-fashioned, but that’s really the whole point of Spendor’s Classic range Spendor arrived on the scene at the beginning of the 1970s, bringing a strong BBC heritage along with a number of interesting innovations that its competitors arguably didn’t fully appreciate. One of the most significant among these was a radical approach to enclosure design. The theory goes as follows: building an exceptionally stiff structure might serve to reduce the amplitude (ie relative loudness) of cabinet vibrations, but it also increases the frequency at which they occur, so that the enclosure coloration tends to occur in the midband where human hearing is most sensitive. The alternative Spendor approach, originally inspired by the BBC’s desire for accurate speech monitoring, is the ‘thin wall’ cabinet approach, backed by heavy damping pads, which pushes the cabinet wall vibrations down into the bass region where they’re considered less intrusive.

Tannoy Definition DC8 A very pretty and compact variation on Tannoy’s timeless Dual Concentric theme One of the oldest names in British hi-fi, Tannoy is currently part of the Danish TC Group and is probably best known for its unique Dual Concentric single-chassis two-way drive unit technology, which first appeared way back in 1948. This £2,500 per pair DC8 is a simple two-way design and the smallest of three Definition models. As the name suggests, an eight-inch (200mm) Dual Concentric ‘double drive unit’ is at its heart, firing a 25mm titanium dome tweeter with ‘tulip waveguide’ horn-loading through the centre of a 145mm flared paper bass/mid cone with a conventional rubber roll surround. A bonus of the construction, of course, is that the tweeter is automatically well protected from prying fingers.
