Magnepan Magneplanar MG-1.4

The Magnapan Magneplanar MG-1.4 is a loudspeaker that uses planar-magnetic technology to produce high-fidelity sound reproduction. Unlike traditional dynamic speakers that use a cone membrane, planar-magnetic speakers use a flat diaphragm made of a thin, lightweight material, coated with a conductive layer, and suspended between magnetic poles. This design minimizes the mechanical deformations that cones can have, reducing distortion and improving transient response.The MG-1.4 is part of Magnapan's Multigraph series, which feature multiple diaphragms to produce a wider soundstage and more detailed imaging. The MG-1.4 uses four such planar-magnetic panels, each optimized for a specific frequency range, to produce a smooth, natural sound across the entire audible spectrum.Some notable features of the MG-1.4 include:- Sensitivity: The MG-1.4 has a nominal sensitivity of 85 dB at 2.83V/m, which makes it relatively efficient for a planar-magnetic speaker.- Impedance: The impedance of the MG-1.4 is rated at 5 ohms, which isn't too low, but it doesn't require a highly-capacitive amplifier to match its load.- Crossover: The MG-1.4 features a four-way crossover network designed to separate the incoming audio signal into four analog outputs for each panel, minimizing the electrical and mechanical interaction between panels and reducing coloration.- Construction: The MG-1.4 is constructed using high-quality materials such as high-density birch plywood, Rohacell foam, and heavy-duty steel frames, to ensure sturdy construction and minimizing vibrations and resonances.Overall, the Magnapan Magneplanar MG-1.4 offers outstanding sound reproduction quality and is a great choice for audiophiles looking for a high-end loudspeaker with a planar-magnetic technology. Its four-panel design ensures a wide soundstage and detailed sound imaging, while its efficient sensitivity and convenient impedance make it easy to drive, making it a top contender among high-end planar-magnetic loudspeakers.
