Legatia L6SE Wide-Bandwidth Midrange/Midbass
History
The Legatia L6SE’s topology is an enhanced Special Edition version of the massively successful
‘original’ first-generation Legatia L6 transducer, which was launched in January 2007 to an
enthusiastic reception of car audio competitors, enthusiasts, and car audiophiles. In the years since
its inception, the L6 midbass/midrange has been included in several national- and world-
championship vehicles and was the midbass of choice for five consecutive years of International Auto
Sound Challenge Association (IASCA) domination by Hybrid Audio competitors from 2007 through
2011.
By winter 2009, a beta prototype pair of Legatia L6SE’s had been refined after hundreds of hours of
testing and development; these highly-evolved drivers were sent to various national- and world-
championship competitors, notably including John Sketoe, multi-USACi and IASCA champion, for
real-world evaluation. Even before any official launch or announcement of the L6 Special Edition
program, John Sketoe competed the Legatia L6SE’s as a wide-bandwidth midbass driver in his 1987
Buick Grand National, and went on to win his class with the highest sound quality score of the entire
2009 USACi World Finals event. Before even being released, no less mention of there being an
official Special Edition program, the L6SE was already crowned championship-caliber product.
Production refinements were complete and the L6SE’s were delivered to an enthusiastic reception on
March 18, 2010. Design tenets incorporated features inclusive and proprietary to the Legatia SE line,
and the L6SE became the reference 7.1-inch driver in Hybrid Audio’s product category known
collectively as the Legatia SE Series.
Attributes
The Legatia L6SE is a 181mm (7.1-inch) wide-bandwidth midbass/midrange driver to compliment
both two-way and three-way system designs, where a point-source midrange and/or dedicated
midbass driver is required. The following are the L6SE’s design attributes:
Basket
The basket of the L6SE is a shared design with the Legatia L6 and Legatia L6V2, for easy upgrade
potential; the L6SE, L6V2, and L6 are interchangeable in mounting topology. The basket is a high-
quality cast aluminum design, and contains a 181mm flange providing for the mounting of the driver
via four screw holes (the use of 4mm cap head screws is ideal). The overall dimensions of the driver
are very amenable for use in the car audio environment, and in locations typical of the standard “6-
inch” driver, or in custom locations at the discretion of the end-user, boasting a depth of 78mm (3.07-
inch). The basket features large openings behind the cone to eliminate chuffing and other
aerodynamic-based noises, as well as provides adequate communication to the back of the cone for
acoustic suspension and proper operation.
Motor
The motor of the L6SE is paramount to the performance of the driver, providing for a flat and wide BL
curve (as a learning note, BL is the equivalent of torque in a car; a car with a flat and constant torque
