Dome
The L1V2 starts with an impregnated fine silk cloth dome diaphragm for a linear tonal character, with
a treated silk surround to damp edge modes and resonances. The L1V2 is efficient, exhibits low
distortion, and has a wide dispersion. The dome is of extremely low mass and is much less
susceptible to mechanical deformation than other designs, and yet yields a smooth response over the
extent of its range.
Motor
The motor assembly of the L1V2 is conventional dynamic, with a
φ 19.5 × 3 H NdFeB neodymium
magnet to ensure a small footprint size and shallow depth. The L1V2 tweeter has a resonance
frequency of 1,830 Hz, providing a considerable amount of flexibility for use with Legatia wide-
bandwidth midbass drivers in point-source two-way front stage systems, as well as continuing to be
the tweeter of choice of point-source Hybrid Audio Technologies three-way and four-way front stage
kits. The power handling was doubled from the original L1 tweeter, and the L1V2 has a nominal
resistance of 4 ohms.
Grille
As mentioned previously, the dome is a fine silk diaphragm that has an acoustically transparent,
perforated steel grille to protect it. A major upgrade over the original L1 is a fully-machined aluminum
body and mounting flange to effectively damp dome and edge modes, reduce dome resonance, and
edge distortion. The mounting flange accommodates three screws for surface-mounted installation;
black anodized Alan-head screws are included with each tweeter kit. The L1V2 tweeter comes in two
colors to ensure cosmetic integration with the vehicle’s surroundings: natural (silver) aluminum, and
anodized black (there is no cost difference between the two colors).
Terminals Cap and Spring-Loaded Terminals
Another upgrade over the original L1 tweeter is the inclusion of an extruded polypropylene cap with
integrated high-end nickel-plated spring-loaded push terminals at the rear of the tweeter’s motor
assembly. The spring-loaded terminals give the end-user flexibility in direct connection with large-
gauge tinned wiring, without the need for crimp terminals. The overall dimensions of the driver are
very amenable for use in the car audio environment, boasting a depth of just 20mm, for the ultimate in
mounting flexibility.
Summary
The Legatia L1V2 tweeter is an excellent step-up in performance over the Unity/Clarus U1/C1 tweeter
driver offered in the Unity and Clarus kits, respectively, and is the bench-mark high-resonance
tweeter in Hybrid Audio’s complete product offering. Equally at home in two-way configuration paired
with a wide-bandwidth midrange or midbass, or as the dedicated tweeter transducer in a three-way
application, the Legatia L1V2 is an exemplary performer, and is eclipsed in performance by only the
Stage VI Legatia pro-series L1, and the Legatia L1 Pro Ring Radiator (R2) tweeters.
