Legatia SE L1 Ring Radiator (R2) Tweeter
History
The Legatia SE L1 R2’s topology is an enhanced “ring radiator” version of the successful low-
resonance Legatia SE L1 Pro. The purpose of the L1 R2 topology was to build upon the success and
efficacy of the Stage VI Legatia SE L1 Pro, but the offer the driver in a radiator ring topology to further
enhance on-axis and off-axis frequency response, increased bandwidth, and lower modal distortion.
The Legatia SE L1 R2 is the culmination of an inordinate amount of time and resources spent testing
and refining this product to the exacting specifications of Hybrid Audio Technologies and our long
heritage of quality speakers. We are certain that this product will provide class-leading performance -
that simply cannot be beat by competing brands – if installed properly.
The Legatia SE L1 R2 is a direct descendant of the massively successful, limited edition Stage VI
Legatia L1 Pro Special Edition (SE) tweeter that was released on November 24, 2009 (please
reference the Hybrid Audio Technologies website for more details on the Legatia L1 Pro SE). The L1
Pro SE was built in extremely limited production and was an evaluative line by Hybrid Audio
Technologies to gauge consumer interest in a super high-end ring radiator design from the company.
The SE tweeters were completely sold out by March 1, 2010. Given the efficacy of the design and its
popularity as the “tweeter of choice” for high-end car audiophiles around the world, the team at Hybrid
Audio Technologies began refining the SE tweeter design in early 2010. Several minor
enhancements were realized to the tweeter’s hard parts during the design process, with the ultimate
goal of producing a driver becoming of the original SE design, but in a permanent, non-limited edition
offering within the Hybrid Audio Technologies line-up.
By late January 2010, beta prototypes had been disseminated amongst Hybrid Audio’s elite group of
world championship car audio competitors, as well as other independent speaker testers, and the
verdict was clear – the Legatia L1 R2 was ready for production. Production refinements included the
Spring and early Summer of 2010, to include features inclusive and proprietary to the L1 R2, and final
production commenced late Summer 2010.
Notably, approximately eight months after launch, using the L1 R2’s as tweeter drivers in his own
sound quality competition car, Scott Buwalda set the highest recorded score of all time in organized
sound quality competition (996 points) at the International Auto Sound Challenge Association
(IASCA
®
) North American Championships on March 19-20, 2011. This achievement has been
memorialized by IASCA
®
in writing as the highest score on record, and it has been noted by IASCA
®
that the score achieved will likely remain the highest combined sound quality and installation quality
score of all time, in any format, in any part of the world.
The Legatia L1 R2 is the world’s finest ring radiator tweeter – bar none. No competing manufacturer
can match the performance of the Legatia SE L1 R2. It is the world’s first and only ring radiator
design that boasts incredible off-axis response, for extreme mounting flexibility in the car environ.
The L1 R2 tweeter is an exceptional super high-end solution for installers, enthusiasts, and car audio
competitors, and provides the tweeter foundation for many of our high-end two-way and three-way
systems.
