Напольная акустика — Magico M6

The M6 is a three-way tower of the M Series by Magico, the California maker, which also includes the smaller M2 and M3 and, more recently, the M9 at the top of the series. It was priced at USD 172,000 per pair on its introduction. Five drivers sit in a sealed enclosure that mixes solid carbon fibre walls with machined aluminium panels.

Key specs that matter

The M6 carries one 1.1 inch diamond-coated beryllium dome tweeter, one 6 inch XG Nanographene cone midrange and three 10.5 inch XG Nanographene cone bass drivers. Sensitivity is 91 dB and nominal impedance is 4 ohm, with a minimum recommended amplifier power of 30 W. Height is 143 cm, depth 66 cm and width 51 cm tapering to 38 cm toward the back, and each speaker weighs 177 kg.

Engineering and use context

Magico builds a six-sided monocoque cabinet whose tapered sides are made from solid carbon fibre about 13 mm thick. The baffle, the narrow back plate and the top and bottom panels are machined aluminium, and the top and bottom plates are about 51 mm thick with compound curves. The curved form avoids flat parallel surfaces and sharp edges, which reduces internal standing waves. The midrange has its own reverse horn-shaped sub-enclosure in a proprietary carbon fibre composite. Its cone uses a graphene-based material that Magico rates as 30% lighter and 300% stiffer than earlier cones, and it is driven by an underhung neodymium motor with dual magnet structures that produce a stable field of 1.7 Tesla in a 15 mm gap. The tweeter dome is beryllium with a vapour-deposited diamond coating. Drivers and the finished speaker were modelled for acoustic, mechanical, electromagnetic and thermal behaviour using finite element analysis. The Elliptical Symmetry Crossover topology links the drivers with parts from Mundorf of Germany and is intended to keep phase linear across a wide bandwidth. Instead of spikes, the rounded bottom panel rests on MPod feet in a tripod layout.

Pairing

With the high sensitivity the minimum recommended power is a workable starting point, yet the low nominal load and three large woofers per side need an amplifier that delivers generous current into low impedance, such as a high-power stereo or monoblock solid-state design. The sealed bass loading means no port needs clearance from the rear wall, although the deep cabinet still takes up floor space. Given the weight of each speaker, the floor must carry a concentrated load on three contact points.

Alternatives

A more compact tower from the M Series is the Magico M3, fitted with three 7 inch bass units in a 145 kg cabinet.
