Legatia SE Carbon Speaker Design Considerations
The Legatia SE Carbon-series component speakers are electrodynamic drivers that are comprised of
a diaphragm that is set in motion by a motor system that has both electrical and mechanical
components. The Special Edition Carbon midbass designs boast several key elements which
enhance the driver’s performance in vehicle-specific applications, notably applications which require a
shallow-depth midbass driver, such as typically found in numerous German-manufactured
automobiles (Audi, BMW, Porsche, and etc.). Likewise, the Carbon midbass’ can be used at the end-
user’s discretion in a variety of automobile settings where a shallow-profile, long-throw midbass is
required. The Legatia SE Carbon midbass differ vastly from the Legatia SE-series wide-bandwidth
drivers, as follows:
• Considerably shallower mounting depth;
• Considerably smaller motor profile;
• Inclusion of a “double-S” treated cloth surround for enhanced excursion, restorative force,
compliance, and edge-mode damping, for authoritative midbass operation;
• Narrower recommended bandwidth operation, as compared to the wide-bandwidth Legatia SE
series, but with enhanced midbass and lower midrange authority;
• Inclusion of a composite carbon fiber cone and dust cap for exceptional strength, while
balancing moving mass and resonance frequency;
The following design tenets are similar by comparison to the Legatia SE-series wide-bandwidth
drivers:
• Same basket diameter, mounting hole, and bolt circle diameter as its sibling Legatia SE wide-
bandwidth driver (but with considerably shallower depth and motor diameter, as described
above);
• Incredibly low inductance;
• High thermal power handling by AES standard;
• High thermal power handling with suggested crossover;
• High compliance of motor system;
• Use of woven dual tinsel lead spider for mechanical balance, improved radial compliance, and
to eliminate tinsel lead slap;
• Inclusion of nickel-plated, spring-loaded binding post terminals for enhanced connectivity;
• Inclusion of high-energy opposing double-stacked neodymium cup and motor for increased
motor performance and smaller diameter motor;
• Inclusion of aluminum radiator for heat dissipation and increased thermal power handling;
• Inclusion of rose-tinted, laser-etched back plate cap with Hybrid Audio Technologies logo and
Special Edition nomenclature.
The following design tenets are typical of all Legatia SE Carbon-series midbass drivers:
Motor
The motor of the Legatia SE Carbon midbass speakers are paramount to the performance of the
drivers, providing for a flat and wide BL curve. The BL curve is flat and extended in all models,
yielding exceptional two-way linear excursion, resulting in the Legatia SE Carbon midbass drivers
being able to accurately track the input signal. Reduced distortion and greater dynamics are the
