Standing over a metre in height, the Olympica III is imposing without being a room-dominator. Our review example was in natural walnut, with joints in clear maple, while accenting this are leather inlays with highlighted stitching. As standard, the front baffle and back are also covered in natural hide. The construction comprises ‘progressive thickness’ triple curvature cabinet walls, with solid walnut clamps reinforcing the structure.

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.

When the BC III was launched in 1973, Spendor’s ads described it as ‘An extension and refinement of theBC I and BC II’, while Thomas Heinitz, doyen of hi-fi consultants in those days, could not resist using the headline‘Hey, big Spendor’. The BC III was rooted in Spencer Hughes’ work at the BBC: he was part of the legendary BBC research team, working under both D E L Shorter and H D Harwood. It had an 8in driver with 40mm voice-coil, working in its own sealed chamber as a midrange unit while the 12in bass unit was reflex-loaded by a carefully designed port. The crossover point was 700Hz.

Here, B&W has launched a floorstander that extends the CM Series upwards and fits into the price slot vacated by the old 804S. Like the 804, the CM10 uses a separate [but new] tweeter module. A standard 50µm-thick dome with most of the centre removed forms a stiffening ring and on the front of this is stuck a full dome only 35µm thick. This gives a higher first breakup frequency, said to be 38kHz, yet with a similar moving mass, compared to the standard 50µm dome.

The M’inenT range [one standmount and two floorstanders] is new from GamuT. The M5s have a tall and commanding presence yet somehow seem less bulky than their paper dimensions would suggest. The cabinet is exceptionally well finished in a flawless real wood veneer and a wide range of finishes is available at extra cost. The three drive units are configured as a two-and-a-half way design, with crossover points at 500Hz and 2.

Magico has wisely decided to ‘trickle down’ its Q series know-how into a new and mildly more affordable series: the S1 and S5 floorstanders. The latter is a good £11k shy of the similarly-proportioned Q3 [HFN Sep ’11] and yet it offers almost exactly the same sensitivity, an even flatter response but a measurably and palpably superior bass extension. The S5’s body comprises three main sections – a thick alloy baffle plus two curved, 0. 5in-thick side extrusions that increase stiffness while minimising internal standing waves.

Customer and retailer reactions have suggested the need for a new Wilson speaker closer in performance to the universally-acclaimed Alexandria XLF [HFN Nov ’12], but one that swallowed no more real estate than a Sasha. With a footprint close to the Sasha’s, the Alexia hosts only a slight increase in height, due mainly to the necessarily larger woofer enclosure. To provide a goodly portion of the XLF’s adaptability, precision and coherence, the smaller Alexia had to offer adjustability of the midrange and tweeter positioning with to-the-millimetre accuracy, according to room specifics and the location of the owner’s ‘hot seat’. That meant a head section with movable segments, but with a volume akin to that of the original WATT.
