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 L8SE’s performance and clarity by deflecting delicate midrange and
treble tones forward of the driver, while minimizing distortion and improving bandwidth.
The L8SE uses a copper shorting cup. The shorting cup consist 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
(IMD).
Tinsel Leads
The tinsel leads for the L8SE are terminated on one side of the voice coil, with a second, unused set
of tinsel leads exiting the opposite side of the termination. Having two sets of tinsel leads reduces the
rocking of the system under high stroke; the spider is mechanically balanced. Additionally the tinsel
leads are bonded directly to the former and brought out to the terminals, which keeps tinsel lead slap
to a minimum and does not compromise the structural integrity of the cone.
Terminals
The Legatia L8SE comes equipped with heavy-duty spring loaded brass core terminals that are nickel
plated to optimize contact, and give the end user flexibility in tinned wire or binding post terminations.
The terminals are designed to accept up to 10-gauge wiring.
Summary
The Legatia L8SE is the ideal multi-purpose super high-end speaker driver. 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 L8SE allows it to be mounted in typical “8-inch” midbass 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 L8SE is Hybrid Audio Technologies Legatia SE high-end
large-format midrange/midbass offering, boasting exceptional performance and a design philosophy
that goes hand in hand with true high-fidelity playback.
