Magnepan has been manufacturing innovative, world class stereo speakers for 47 years. Jim Winey, the inventor of the Magneplanar loudspeaker, first owned electrostatic loudspeakers and began experimenting to design an improved electrostatic speaker. In 1969, Jim invented the Magneplanar, a thin-film magnetic equivalent to the electrostat and founded Magnepan. Magneplanars are American-made with virtually all American parts. And they are proud to say– “Made in America. Sold in China”.

The Magneplanar 3.7i loudspeaker was conceived and designed by perfectionists, for perfectionists. The 3.7i is a 3-way, full-range ribbon design with a quasi-ribbon bass and midrange, and true-ribbon tweeter.

Ribbon Tweeter

The Magneplanar direct-coupled ribbon tweeter has no equal in high frequency sound reproduction. With its 360 degree radiating dipole design, the Magneplanar ribbon tweeter is found in our award winning 3.7i and 20.7 speakers. At 1/10th the thickness of a human hair, the Magneplanar ribbon tweeter sets a standard for high resolution. You’ll find yourself hearing details in the music you never heard before.

Quasi-Ribbon

The quasi ribbon driver is a deviation from the true ribbon design. A very thin film backing is used to hold the delicate ribbons in place. One of the advantages of quasi ribbon drivers is extremely wide frequency band width and high power handling. The result in the 20.7 is low distortion and seamless ribbon clarity–a sound so clear and effortless that it has changed the thinking of thousands of audiophiles about planar speakers.The use of quasi ribbon technology down into the lower midrange and bass will provide a new level of coherence.

The 3.7i is not big from an acoustical standpoint. However, the bass driver is big. If Magnepan sold the portion of the speaker from 200 Hz up, you could put it in the average apartment. Yes, it is tall, but very narrow. The ideal speaker would be a massless line-source that would look like a pole–from the floor to the ceiling. The 3.7i comes as close to that ideal as is possible with real-world devices.
