The Legatia Pro L1 SE is a limited-edition, super high-end mobile audio tweeter based upon the architecture of the original and highly-acclaimed Hybrid Audio Technologies Legatia L1 Pro transducer. At the onset of the Legatia Pro-Series program, Hybrid Audio wanted to be sure that the Pro-Series tweeter could be listened to for long listening sessions with no noticeable listener fatigue, and the Pro L1 answered the call. The Pro L1 SE is an advancement of the original Legatia L1 Pro design, boasting a radiator ring diaphragm for exceptional polar response and an even broader frequency response, and lower resonance frequency than the original L1 Pro.
The Legatia Pro L1 SE is ring radiator tweeter that has superior damping and extended frequency response. The Pro L1 SE is a light and transiently fast tweeter in a 25mm body that doesn’t suffer from typical “heaviness” in tonal quality, typically associated with damped, large-diameter dome tweeters; the L1 Pro SE can be used for the reproduction of upper midrange and treble frequencies in dedicated two-, three-, and four-way front stage systems. The Pro L1 SE has exceptional polar response, and remains small enough to install in typical locations within a vehicular environment. The Pro L1 SE is the new benchmark for radiator ring diaphragm tweeters.
The Legatia Pro L1 SE is a 25mm (1-inch) ring radiator-type tweeter which has an extended linear response and exceptional transient response. The design offers a wide dispersion pattern to make for flexible on- and off-axis installation and speaker location.

The Pro L1 SE is the new benchmark for radiator ring diaphragm tweeters.
The Legatia Pro L1 SE is a 25mm (1-inch) ring radiator-type tweeter which has an extended linear response and exceptional transient response. The design offers a wide dispersion pattern to make for flexible on- and off-axis installation and speaker location.
The L1 Pro SE has several unique features that ensure performance is superior to all other designs in this category. The ring radiator geometry is notorious for delivering a flat, extended response, but many radiator designs have suffered historically from poor off-axis response. The main L1 Pro SE criteria was to have a ring radiator that could work exceptionally well in a car environment, with an end-user’s choice of either on- or off-axis operation with good polar response. The geometry of the wave guide was paramount to achieving this result and was the subject of a concerted effort by Hybrid Audio Technologies engineers. The wave guide also prevents phase cancellation for uniform frequency response and uniform polar radiation. The addition of the wave guide is an improvement over a conventional dome tweeter design simply for the fact that the diaphragm is terminated not only at its edges, but also at the center of the diaphragm as well. This feature improves the damping of modal distortion and resonance. In concert with the wave guide is a treated fine cloth diaphragm to ensure smooth frequency response.
The Pro L1SE is efficient, exhibits low distortion, and has a wide dispersion; the L1 Pro SE has a slightly heavier moving mass than the L1 Pro, which in turn has afforded more damping character, while the resonance has been lowered by 120 Hz over the L1 Pro (580 Hz). Nominal and thermal power handling has also been improved over the original L1 Pro transducer; the Pro SE tweeter has a very high power handling with proper filtering, and the L1 Pro SE diaphragm is much less susceptible to mechanical deformation than other designs, and yet yields a smooth response over the extent of its range.
