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.

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.

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.

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.
