- The magnet pole yoke, designed with magnetic flux analysis software, helps to achieve perfect and homogeneous saturation of the magnetic gap for the benefit of the voice coil stroke. This reduces distortion and increases dynamics.
- A pure copper ring placed in the air gap helps reduce the inductance of the voice coil so that it offers minimal resistance during high frequency reproduction. This means better high-frequency response, enabling the speaker to reproduce high-frequency sounds more accurately. Reducing inductance contributes to better handling of rapid transitions of audio signals. This can improve the speaker's ability to more accurately reproduce transient sound pulses.
- TCA to control the flow of air moved by the cone creates aperiodic damping resistance and dictates that the release of energy accumulated in the movement of the speaker occurs in a controlled and fast manner, without creating persistent oscillations. This contributes to a more precise and faithful response to the audio source and to the accuracy and overall sound quality.
- Main twin coupled neodymium magnets. This pair of neodymium high-temperature resistant magnets are one of the most powerful motor magnet structures for this size of car audio midrange. They are made from a high-grade neodymium and allow the size and bulk of the magnetic motors to be greatly reduced.
- Pole plate CNC machined from a solid piece of ultra-low-carbon steel.
- The built-in, substantial terminals accept large gauge cables and are gold-plated to prevent any loss of power generated by the amp.
- Die cast-aluminum and powder-coated basket offers very low resistance to the passage of air, and its shape (verified by FEM analysis) reduces vibration and resonance.
- Wide, lightweight Nomex voice coil with aluminum winding contributes significantly to the wide bandwidth extension.
- Large balanced Conex™ spider damper device ensures linear excursion in both directions, reducing distortion.
- The cone is made of high modulus carbon molded under vacuum and autoclave, a technology rarely used in speakers because of its cost, but brings enormous benefits in terms of naturalness of reproduction and high transient dynamics.
- The NBL rubber surround has a shape designed to ensure very smooth movement at very low excursion, becoming increasingly controlled as the excursion increases and approaches the limit. This, too, helps to make this speaker extremely dynamic and capable of handling high power.
- The laminated aluminum dust cap helps extend this midrange's frequency response upward, and its shape and size helps equalize and linearize the frequency response.
- The CNC-machined aluminum ring secures the rubber suspension on the edge, ensuring perfect fastening and centering.
- CNC-machined aluminum grille (optional)
