This four-way, six-driver floor standing system features the world’s first loudspeaker enclosure to combine inner and outer skins of carbon fiber with a revolutionary aluminum honeycomb core. Included with the M9 is a state-of-the-art analog outboard active crossover, the MXO. Designed in-house, this carefully crafted unit handles bass/midbass frequency separation. In addition, the M9 benefits from latest generation of Nano-Tec speaker cones, featuring Aluminum honeycomb cores. The result is a revelation, a loudspeaker that can present intense crescendos with unconstrained power, yet reproduce the most delicate musical passages with transparency and stunning microdynamic detail.
Carbon fiber enclosure with Aluminum honeycomb core
The enclosure also incorporates the latest application of constrained layer damping using aerospace composites, plus familiar features of Magico construction including a baffle board of 6061 T6 aircraft aluminum and front-to-back tensioning rods. Through many rounds of Finite Element Analysis modeling, we fine-tuned the enclosure design to suppress resonances and any possibility of stored energy. We also calibrated the organic shape of the enclosure and machined the front baffle to reduce diffraction effects to near zero. Sound waves from the drivers propagate without obstruction. You can hear the difference. The resulting soundfield replicates that of the recording space. Even though the M9 has a commanding physical presence, in sonic terms, it completely vanishes.
New beryllium-diamond dome tweeter
Magico has long recognized that the bending and flexing of non-pistonic motion in a soft dome tweeter leads to large-scale distortion. That’s why we chose the high strength and light weight of Beryllium. And we went even further, enhancing Beryllium with the incredible stiffness of diamond, carefully applied by chemical vapor deposition. This enabled us to go larger, building the world’s first 28 mm Beryllium dome and improving performance without the weight penalty that diamond normally incurs. Now the M9 raises the stakes with an even more refined 28 mm Beryllium-diamond dome tweeter. The new drive unit delivers high-frequency reproduction of extraordinary accuracy, confirmed by Laser Interferometry testing and by careful listening. You’ll hear microdynamics of even greater subtlety, revealing musical detail with even greater clarity.
Graphene, the hallmark of the Nano-Tec cones, is a hexagonal lattice of carbon just one atom thick. Graphene combines incredible stiffness with the highest tensile strength of any material known to science – some 40 times that of carbon steel. The resulting cone is so rigid that, inverted on the ground, it will not deform after being run over by a sedan.
3, 4 and 5-inch voice coils on vented pure Titanium formers
As a cone driver plays intense musical peaks, voice coil temperatures can climb over 100° F (40° C) in a single second. Heating can double the voice coil’s DC resistance, alter the frequency response curve and compress the music as much as 3 dB – a substantial nonlinearity. Magico drivers overcome these distortions. The M9 cone voice coils are huge – 3, 4 and 5 inches in diameter – for much faster dissipation of heat and greater control over the cone. Vents in the voice coil formers provide another level of heat dissipation. We chose formers of pure Titanium for its ideal combination of stiffness and resistance to eddy currents.
Underhung voice coil and oversized Neodymium magnets
The force that the magnetic circuit applies to the voice coil can drop as much as 50% as the voice coil moves away from the central, rest position. This drop-off can be asymmetrical. Motion does not faithfully track the input signal, generating substantial harmonic and intermodulation distortion. Magico Nano-Tec drivers exercise absolute control over voice coil movement by providing underhung voice coils in a magnetic circuit of tremendous power. We use Neodymium magnets with 16 times the magnetic energy per unit volume of Ferrite. In preference to an array of small Neodymium magnets, we select uncommonly large Neodymium ring magnets. As an extra measure against asymmetry, these drivers deploy a matching magnet on top. The result is prodigious flux density, up to 1.7 Tesla (17,000 Gauss), maintained across uncommonly long air gaps, up to 36 mm. This enables distortion-free output up to 120 dB SPL at 1 meter.
6-inch midrange driver (x1). The new midrange features a remarkable 4-inch voice coil to help maintain linear output all the way to 120 dB SPL at 1 meter. This results in unmeasurably low distortion throughout the driver’s operating range.
11-inch mid bass drivers (x2). This entirely new driver incorporates an N52 grade Neodymium ring magnet of unusual size: 120 mm diameter x 8 mm height, plus a second matching magnet on top for complete control of voice coil movement. It is a new benchmark in linearity.
15-inch bass drivers (x2). The new bass driver features a cone molded by 26,500 pounds of pressure. An uncommonly long 36 mm air gap facilitates tremendous linear excursion, ±15 mm, at high sensitivity. You hear the lowest three octaves of bass with full extension and no mid-bass exaggeration.
From cone materials to voice coils to magnetic circuits, each one of these features improves linearity and reduces audible distortion. Taken together, they represent the literal state of the art. These are the most advanced dynamic drivers ever made.
Magico Analog Crossover (MXO)
The 120 Hz crossover frequency between the bass and mid-bass drivers poses a special challenge. At such a low frequency, a passive crossover would require huge inductors and capacitors. Even if the very best parts were auditioned and selected with care, such large circuit elements would incur unavoidable, substantial losses. To overcome this issue, we created an analog, active 2-way crossover, the Magico Analog Crossover or MXO. This substantial component provides steep filter slopes without any sacrifice in signal quality.
The crossover’s meticulous design features Linkwitz-Riley filters to deliver 24 dB per octave slopes at the crossover frequency of 120 Hz. Designed in-house from own platform, the analog crossover is fully balanced with completely discrete circuitry from input to output. Open architecture accommodates additional filter topologies. Precision step attenuators provide 0.5 dB/step control of each output, using a proprietary technique to ensure purity in the signal path. The external power supply chassis regenerates AC and applies active regulation to every part of the circuitry.
A pair of M9 loudspeakers requires two stereo or four monaural amplifiers.
The M9 tweeter, midrange and mid-bass drivers are controlled by a three-way passive crossover with acoustical target 24 dB-per-octave Linkwitz-Riley filters. Magico’s elliptical symmetry crossover design preserves maximum frequency bandwidth with minimal IM distortion.
