Magnepan MG1.7i

The Magnepan MG1.7i is a remarkable full-range planar-magnetic loudspeaker that builds upon the legacy of the highly regarded MG1.6. Released as an updated version of its predecessor, the 1.7i enhances the overall performance while retaining the signature characteristics that make Magnepan’s speakers so beloved by audiophiles—transparent, open, and incredibly detailed sound.

Magnepan’s planar-magnetic technology utilizes a thin, flat diaphragm suspended in a magnetic field, which is different from traditional dynamic drivers. This design allows the MG1.7i to produce sound with far greater efficiency, delivering a more natural and coherent soundstage than conventional cone speakers. The MG1.7i is particularly known for its expansive soundstage, transparency, and precise imaging, creating an immersive listening experience. These speakers are well-suited for those who appreciate a more “live” or “realistic” listening environment, often described as “the closest thing to hearing live music.”

Design & Build Quality

The design of the Magnepan MG1.7i is sleek and minimalistic, with a frameless, rectangular panel that is typically mounted on sturdy stands. The front panel houses the speaker’s ultra-thin diaphragm, while the rear features an aluminum honeycomb construction that reduces resonance and increases rigidity. This attention to detail helps reduce unwanted distortion and ensures accurate sound reproduction.

At 6 feet tall, the MG1.7i has a significant presence in any room, but its slender design doesn’t dominate the space. The speaker’s unique planar-magnetic design requires precise placement for optimal performance. While not the most room-friendly option for small spaces, these speakers shine in medium to large rooms where they can be positioned away from walls to allow their wide soundstage to fully develop.

Performance & Sound Quality

The Magnepan MG1.7i offers an exceptional balance of deep bass, clear midrange, and shimmering highs. The low-end performance, often a challenge for planar speakers, is impressive for its depth and precision, despite the speaker’s relatively compact size. The midrange, where much of the music’s emotion and energy resides, is rendered with remarkable accuracy, giving voices and instruments a lifelike presence. High frequencies are airy and detailed, free from harshness or distortion, even at high volumes.

Reviewers have consistently praised the 1.7i for its transparency and expansive soundstage. According to The Absolute Sound, “The Magnepan MG1.7i delivers a sound that’s difficult to match in terms of naturalness and fluidity. Its ability to reproduce a wide soundstage, while remaining balanced in all frequencies, is exceptional.” Stereophile also lauds its imaging: “The speakers are able to place instruments and vocals with pinpoint accuracy, drawing listeners into the performance.”

However, like all planar speakers, the MG1.7i’s best performance is achieved when the speakers are given ample space to breathe, and they benefit from proper amplification. The speakers pair well with high-quality amplifiers that can provide adequate power, particularly for handling the complex demands of the low-end.
