Legatia L1 Pro Tweeter
History
The Legatia SE L1 Pro’s topology is an enhanced “low resonance” version of the massively
successful Legatia L1V2. The purpose of the L1 Pro topology was to build upon the success and
efficacy of the Stage V Legatia L1V2, but offer it in a package with considerably lower resonance
frequency for potential use in two-way applications, or where a tweeter with low resonance was
needed. The L1 Pro was launched in February 2008, and was the first product developed and
released in the Legatia Special Edition and Pro Series. In the years since its inception, the L1 Pro
has been used successfully in organized car audio sound quality competition, notably including two-
time Canadian and IASCA North American championship competitor John “Fozz” Myers’ vehicle.
The
Legatia SE L1 Pro is the reference soft-dome tweeter driver in Hybrid Audio’s product category
known collectively as the Legatia SE Series.
Attributes
The Legatia SE L1 Pro is a 58mm (2.3-inch) O.D. “low resonance” wide-bandwidth tweeter driver.
Continuing on in the tradition of exceptional tweeter design and manufacturing by Hybrid Audio
Technologies, the Legatia Pro L1 is an articulate, detailed, and tonally-correct tweeter in a slightly
larger diaphragm than its sibling, the Legatia L1V2. The Pro L1 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 can be used for the reproduction of treble
frequencies in dedicated two-, three-, and four-way front stage systems. The Pro L1 has exceptional
polar response, and remains small enough to install in typical locations within a vehicular
environment.
At the onset of the Special Edition and Pro-Series Legatia program, we 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 answers the call. The Pro L1 does an immaculate job of recreating tones well into the
vocal midrange frequencies, should the user decide to employ an exceptionally low crossover
frequency. The Pro L1 sets the new benchmark for car audio tweeters; it is the best soft-dome car
audio tweeter available today, irrespective of price. The L1 Pro is available in two finishes: brushed
(natural) aluminum and anodized black.
Dome
The Pro L1 starts with an impregnated fine cloth silk dome diaphragm for a linear, smooth frequency
response, with a treated silk surround to damp edge modes and resonances. The Pro L1 is efficient,
exhibits low distortion, and has a wide dispersion; the dome is of exceptionally low mass and has an
extremely high power handling with proper filtering. The Pro L1 dome design is much less
susceptible to mechanical deformation than other designs, and yet yields a smooth response over the
extent of its range.
