Legatia L6V2 Wide-Bandwidth Midrange/Midbass
History
The Legatia L6V2’s topology is an enhanced “version 2” 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. When it came time to
enhance the L6, we were very cognoscente of the L6’s midbass abilities, and had three general
project objectives: 1) enhance the L6’s ability to effectively reproduce a wider frequency spectrum for
possible application as a dedicated full-range driver in a two-way application, or as a midbass in a
wide-bandwidth three-way application, 2) to enhance the L6’s distortion and inductance
specifications, and 3) to improve power handling, sensitivity, motor strength, and impulse response
through more displacement and lighter moving mass and the inclusion of a proprietary opposing neo-
ferrite motor system. The L6V2 joined Hybrid Audio Technologies’ Legatia L1V2, L8V2, and L3V2 as
the fourth driver in the Legatia series to be enhanced with performance eclipsing the first iteration of
each design. To this end, the L6V2 development began in January 2011, and the first prototypes
were developed by company founder and lead designer Scott Buwalda.
By early Summer 2011, a beta prototype pair of Legatia L6V2’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 for real-world evaluation, including Todd Luliak, MECA champion.
After countless hours testing on the speakers under various circumstances, both as a dedicated
midrange and as a wide-bandwidth full-range driver, final approval was given. Production refinements
were late Summer of 2011, to incorporate features inclusive and proprietary to the Legatia line, and
final production commenced September 2011. The Legatia L6V2 was launched in October 2011 and
is the reference 7.1-inch driver in Hybrid Audio’s product category known collectively as the Legatia
Series.
Attributes
The Legatia L6V2 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 L6V2’s design attributes:
Basket
The basket of the L6V2 is a shared design with the Legatia L6SE for easy upgrade potential; the
L6V2 and L6SE 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 76mm (3-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.
