The Legatia L3SE

The Legatia L3SE is a 93mm (3.7-inch) “small format” wide-bandwidth midrange driver to compliment three-way system designs, or in two-way designs where the L3SE is earmarked as the full-range speaker (for midrange and treble duties without the use of a tweeter). The Legatia L3SE’s topology has been based off of the massively successful Stage III Legatia L3 transducer, which was first launched in April 2006 to an enthusiastic reception of car audio competitors, enthusiasts, and car audiophiles. In the years since its inception, the L3 midrange has been included in more International Auto Sound Challenge Association (IASCA®) national and worldchampionship vehicles than any other midrange in this period of time. When it came time to develop the SE series, the first product earmarked for production was the Legatia L6 SE midrange/midbass. In Spring 2009, the first prototypes were developed by company founder and lead designer Scott Buwalda, and the concept of an SE series was born.
