" the 1.7s are intoxicatingly realistic. There is something about Maggies that simply sounds like the real thing, particularly in the midrange, particularly on voices." -Jonathan Valin Magnepan 1.7 review
The 1.7i is a departure from Magnepan's 41-year history of using planar magnetic drivers for the bass or lower midrange. The use of quasi ribbon technology down into the lower midrange and bass provides a new level of coherence.
What is a 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 1.7 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 1.7i also boasts a quasi ribbon super tweeter with a wide "sweet spot," and one step closer to the delicacy and detail of Magnepan's true ribbon design.
