The Legatia L3SE is a 93mm (3.7-inch) “small format” wide-bandwidth midrange/full-range driver to compliment both two-way and three-way system designs, where a point-source midrange and/or full-range driver is required. The following are the L3SE’s design attributes:

 

Driver specifications are available by following this link.

 

Basket

The basket of the L3SE is a shared design with the Legatia L3V2 and the original Legatia L3 for easy upgrade potential; the L3, L3V2, and L3SE are interchangeable in mounting topology. The basket is a high-quality cast aluminum design, and contains a 93mm flange providing for the mounting of the driver via four screw holes (the use of 3mm 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 “3-inch” driver, or in custom locations at the discretion of the end-user, boasting a depth of just 44mm (1.7-inch), 1mm deeper than its Legatia L3V2 counterpart. 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 L3SE 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 curve provides much better acceleration and performance than a car with a peaky, non-constant torque curve). The BL curve is flat and extended, yielding 6mm of two-way linear excursion, resulting in the L3SE being able to accurately track the input signal. Reduced distortion and greater dynamics are the immediate sonic benefits. The motor of the L3SE includes an opposing double-stacked NdFeB magnet to improve restorative force, compliance, motor strength, displacement, and power handling. The magnet assemblies are fully surrounded by the voice coil.

 

Voice Coil

The voice coil diameter of the L3SE is a large 25.5mm (1-inch), which is the proper balance between size and moving mass in super high-end mobile audio midranges/full-range drivers. The voice coil diameter serves several key functions: elevated power handling, dissipation of heat (thereby lowering power compression), and maximizing the size of the magnet assembly for enhanced motor compliance. The voice coil is high-purity aluminum, which is superior to copper for heat dissipation, as well as significantly reduced moving mass. The result is an extremely lightweight winding with good power handling and low inductance.

 

Suspension

The inverted surround is butyl rubber which is highly consistent and does not suffer the variance of natural rubbers. This rubber surround terminates mechanical vibrations well, having a low stiffness for positive damping of resonances. The spider material was chosen for optimal performance; the spider is a 90/10 cotton/Nomex blend with single-dip low viscosity phenolic. This material provides the stiffness desired without being overly brittle or stiff, where vibrations in the spider are well damped and do not translate into the former or the cone.

 

Cone

Like other Legatia SE midrange designs, you will find no composite or metal cone materials used on the L3SE, as our approach to point-sourcing is to allow the Legatia SE midbass/midrange driver to effectively play into upper treble frequencies. The Legatia L3SE is a cone-type driver consisting of a proprietary hybrid paper diaphragm with extremely low moving mass. Paper is widely acknowledged as the best-damping material, as it provides the near optimum balance of strength and weight. The cone has been treated with a water-resistant element at the rear to accommodate door mounting, or other areas prone to occasional contact with liquid. The cone design offers a wide dispersion pattern to make for flexible installation and speaker location. The Legatia L3SE has an outstanding extended frequency response; the usable frequency range of this driver exceeds seven complete octaves of usable bandwidth on-axis (140 Hz – 18,000+ Hz). Even off-axis, the L3SE faithfully recreates more than five full octaves of information, for the ultimate “small-format” midrange/full-range driver.

 

Tinsel Leads

The tinsel leads for the L3SE are terminated on one side of the voice coil. The tinsel leads are stitched into the spider and bonded directly to the former and brought out to the terminals, which completely eliminates tinsel lead slap and does not compromise the structural integrity of the cone.

 

Phase Plug and Shorting Rings

The L3SE comes equipped with a phase plug pole piece extension at the center of the cone. The phase plug is aluminum and, by design, ensures enhancement of the total inductance profile, providing much of the inductance reduction benefits noted. The phase plug is plated with rose-tinted copper, which by design does not negatively reduce eddy current, and adds thermal dissipation potential, not to mention sleek, class-leading cosmetics. The phase plug extends well down inside the pole vent and acts as a very large and efficient heatsink for any heat that radiates into the pole. The highest frequencies of audio emanate from the area around the center of the cone and the lower frequencies are produced by the area of the cone that is farther from the center. The phase plug pole piece extension improves the L3SE’s performance and clarity by deflecting delicate midrange and treble tones forward of the driver, while minimizing distortion and improving bandwidth.

 

The L3SE uses a copper shorting cup. The shorting cup consists of an optimally sized and placed copper (Cu) cup to create a total inductance profile that is not just low but flat over stroke, frequency, and power. Inductance is the number one limiter of high-frequency extension and modulation of inductance with stroke, frequency, and power, and is the primary source of intermodulation distortion

 

Terminals

The Legatia L3SE comes equipped with heavy-duty nickel-plated spring-loaded push terminals for both positive and negative, which is an enhancement over the L3V2 model. The terminals optimize contact and give the end-user flexibility in tinned wire or binding post terminations

 

Summary

Mechanical and electrical parameters are amenable to a variety of different installations and speaker locations. This driver is intended to be used in an infinite baffle configuration; a simple, solid baffle, solidly attached to the car’s chassis with available airspace at the rear of the baffle is all that is required for optimum operation. The size of the L3SE allows it to be mounted in typical “3-inch” midrange locations within a vehicle, or in custom locations at the discretion of the end-user, as long as there is adequate airspace behind the driver to allow it to maintain proper damping and acoustic suspension

 

At home in virtually any arrangement, the L3SE is Hybrid Audio Technologies Legatia SE high-end small-format midrange offering, boasting exceptional performance and a design philosophy that goes hand in hand with true high-fidelity playback.

Love at first sight.....good customer service and fast shipping....Speaker is Incredible

worth every penny!!

Installed in the dashboard of my dodge ram to bring the soundstage higher up. Clean sound reproduction at any volume. Gives the impression you're front row at a live show

Best full range driver on the planet!
Written by Robert on 27th Feb 2014

I was deciding between a three way or two way setup for the front stage of my Nissan Altima coupe. After speaking with Bob Morrow, I decided to go with the L6v2 and L3se, actively crossed over using a DSP. WOWWW!!! I heard that these drivers could play the full range of audible frequencies cleanly, but I never imagined it would sound like this. Very detailed, no excess coloration, just beautiful music. I decided to stay with this same setup after I sold the Altima and upgraded to the Cadillac CTS-V coupe. I even purchased another set of L3SE's to use for the center channel in my new setup as well. Absolute top of the line drivers. I refuse to put any other drivers in either my car or my wife's. Definitely hooked on HAT!! Thanks Scott , Bob, and the entire HAT team!

Great speakers, great company

An amazing set of drivers from a great company. Their extended frequency range lets you play the whole vocal range through one component, eliminating crossover problems, alignment problems, lobing, etc. Overall the build quality is very high, but one of my drivers had a small issue with a wire terminal. Since I live in Georgia, 12vElectronics arranged for me to ship the driver directly to the Hybrid Audio headquarters. They sent a replacement driver to me via FedEx, and it arrived so quickly that I'm certain they turned it around the same day!
