Magnepan 20.7x Floorstanding Speaker (Pair): Flagship X Series Planar Performance

The Magnepan 20.7x Floorstanding Speaker (Pair) brings Magnepan's premium X Series refinement program to the company's flagship single-panel loudspeaker. Its imposing three-way architecture combines an expansive quasi-ribbon bass section, a dedicated quasi-ribbon midrange, and an ultra-low-mass true ribbon tweeter to reproduce music with exceptional scale, coherence, transparency, and dynamic authority.

Unlike conventional loudspeakers that place cone drivers inside an enclosure, the 20.7x uses broad, lightweight diaphragms operating as open-baffle dipoles. The absence of a traditional cabinet helps eliminate box resonance and stored energy, allowing voices and instruments to emerge within a wide, deeply layered soundstage rather than appearing to come directly from the speaker panels.

The Magnepan 20.7x Floorstanding Speaker (Pair) applies the X Series principles of simplification, component betterment, and balancing throughout the electrical signal path. Premium crossover components, optimized wiring, fewer unnecessary junctions, improved connections, and extensive component testing help preserve more of the signal delivered by the amplifier.

Standing approximately 79 inches tall and 29 inches wide, each 20.7x provides an immense radiating surface capable of moving air with remarkable control. Its large bass and midrange panels deliver realistic image height and natural instrumental scale, while the true ribbon tweeter reveals fine high-frequency detail with exceptional speed and delicacy.

Handcrafted in White Bear Lake, Minnesota, the Magnepan 20.7x Floorstanding Speaker (Pair) is intended for reference-grade systems with the room, amplification, and source quality required to reveal its full potential. Properly installed, the 20.7x can create an immersive wall of sound with powerful bass, lifelike dimensionality, and the effortless openness associated with Magnepan's finest loudspeakers.

Highlights & Benefits

• Flagship Three-Way Planar Design — Dedicated quasi-ribbon bass and midrange sections integrate with a true ribbon tweeter for full-range, reference-level reproduction.
• True Ribbon Tweeter — An extremely lightweight, freely suspended aluminum ribbon delivers airy, extended, and highly resolved high frequencies.
• Quasi-Ribbon Midrange — A large planar midrange surface reproduces voices and instruments with outstanding coherence, speed, and natural scale.
• Quasi-Ribbon Bass System — The extensive planar bass section delivers deep, articulate low frequencies without relying on a conventional cone woofer or enclosure.
• Push-Pull Magnetic Operation — Magnets positioned on both sides of the bass and midrange diaphragms provide more uniform driving force and improved control.
• Premium X Series Refinement — Upgraded components, optimized wiring, improved connections, and extensive balancing elevate the established 20.7 platform.
• Simplified Signal Path — Reduced wire length, fewer mechanical junctions, and carefully arranged crossover circuits help minimize signal degradation.
• Precision Component Matching — Crossover parts and completed networks are repeatedly measured and paired to maintain close consistency between the two speakers.
• Open-Baffle Dipole Radiation — Front- and rear-radiated sound creates an expansive presentation with exceptional depth, ambience, and image size.
• Handcrafted in the USA — Each pair is carefully assembled, tested, and balanced by Magnepan in White Bear Lake, Minnesota.

Technology & Performance

Three-Way Full-Range Ribbon Architecture — The 20.7x divides the audible spectrum among dedicated quasi-ribbon bass and midrange sections and a true ribbon tweeter. Each section uses a large, low-mass radiating surface to reproduce its assigned frequency range with minimal stored energy and exceptional transient response.

True Ribbon High-Frequency Reproduction — The true ribbon tweeter uses an ultra-thin aluminum ribbon freely suspended within a magnetic field. Because the ribbon functions as both conductor and diaphragm, it has extremely low moving mass and responds rapidly to subtle changes in the musical signal.

Push-Pull Quasi-Ribbon Midrange — The midrange section places an aluminum conductor on a lightweight diaphragm positioned between opposing magnetic structures. This push-pull arrangement distributes force more evenly across the diaphragm, supporting lower distortion and greater clarity through the critical vocal range.

Large-Area Planar Bass — Most of the 20.7's radiating area is devoted to bass reproduction. Rather than pressurizing a cabinet with a cone woofer, the broad planar surface moves a shallow wavefront through the room, producing low frequencies with speed, pitch definition, and natural timbral character.

Simplification — Magnepan's X Series engineers reduce unnecessary components, excess wiring, mechanical connections, and signal-path mass wherever the design permits. A more direct route between the amplifier terminals and the planar drivers helps preserve low-level information and transient detail.

Component Betterment — Components between the speaker input and the drivers are evaluated and upgraded using higher-quality conductive and dielectric materials. Premium capacitors, inductors, resistors, wiring, and connections help reduce component-related distortion and improve separation.

Precision Balancing — Individual components are measured repeatedly, sorted, and matched before installation. Completed crossover assemblies are also tested to maintain close electrical consistency between the left and right loudspeakers, supporting stable imaging and tonal accuracy.

Optimized Wiring and Connections — Carefully planned layouts shorten wire runs and reduce the number of junctions in the signal path. High-quality copper conductors and permanent soldered connections are used where appropriate to maintain signal integrity.

Dipole Room Interaction — The 20.7x radiates energy from both the front and rear of each panel. When given sufficient space from the wall behind it, the rear wave contributes to a broad, dimensional soundstage with natural ambience and realistic image depth.

Reference-Scale Presentation — The 20.7x's substantial panel area allows it to reproduce orchestras, pianos, drums, voices, and other full-scale sources with convincing physical dimensions. The soundstage can extend well beyond the speaker boundaries while retaining precise image placement.
