DESCRIPTION

Woofer | 300 W Peak Power | 165 mm (6.5 in.) | 4 ohms
The Audison VOCE II AV 6.5 P II woofer is engineered to deliver exceptional sound clarity and precision. It naturally rolls off at off-axis positions, eliminating the need for a low-pass filter in most door installations and reducing phase shifts common with other filters. It can employ a gentle 6 dB/Octave filter to enhance low and mid-bass tones, further enriching sound quality. The woofer's OEM-style connector, compatible with FASTON terminals and designed for seamless integration, features a unique T-shaped pole piece with an aluminum ring to minimize distortion and enhance frequency response.

Give Sound Its True Voice
Audison Voce II, the second generation of our iconic VOCE speakers, challenged us—to rethink how we design, test, and manufacture speakers. We've revamped materials, supply chains, assembly techniques, and packaging. Our goal was to "unlearn" to innovate and to "reinforce our expertise" where we knew we were on the right track. This dedication ensures that every aspect of VOCE II not only meets but exceeds the sophisticated demands of today's car audio enthusiasts.

AV 6.5 II mid-bass
AV 6.5 II delivers uncompromising power and control in reproducing bass and mid frequencies. Designed to handle up to 150W RMS, this woofer is perfect for those seeking an extended frequency response with powerful dynamics free of distortion.

Powerful motor for better performance
AV 6.5 P II features powerful magnetic motors, known for releasing large amounts of energy while maintaining exceptional thermal stability. The motor reveals a T-shaped pole piece incorporating an aluminum ring. This innovative addition minimizes distortion during high excursions and linearizes the frequency response for superior clarity and precision. The geometry of the magnetic assembly was optimized using FEM (Finite Element Method) simulation software, allowing the magnetic field to be concentrated in the voice coil, improving efficiency and the precision of the sound response. This allows the drivers to deliver dynamic, distortion-free sound, even during complex and rapid musical variations.

Minimum Inductance for an extended frequency response
A key area of ​​research focused on reducing voice coil inductance modulation. By magnetically saturating the motor pole and using a copper short-circuit ring for mid-range and an aluminum short-circuit ring for mid-bass, greater extension towards the midrange frequencies was achieved.

40 mm CCAW voice coil
With the powerful magnet and a 40 mm CCAW (copper-clad aluminum Wire) voice coil, the AV 6.5 P II guarantees linear response across the entire low- and mid-frequency spectrum. Its versatility allows it to work seamlessly with the DSP, optimizing sound performance in any condition, always ensuring natural and dynamic reproduction.

OEM and faston connectors for perfect integration
AV 6.5 II P is equipped with both an OEM-style automotive connector and traditional Faston connectors. This option allows the installer to choose the connection method best suited to the specific project's needs. The availability of both connections simplifies and streamlines the installation process. Thanks to this feature, installers can work more efficiently without constraints, ensuring optimal results in both sound performance and vehicle integration. The dual connection option represents another step towards customization and adaptability, meeting the needs of every car audio enthusiast.

Die-Cast Aluminum Basket: Engineered for Optimal Aerodynamics
Aerodynamic efficiency was a primary goal for both components. The die-cast aluminum basket, with four pairs of spokes, was designed to provide a rigid structure while minimizing airflow resistance around the cone. This allows the cone to move freely, improving response and reducing unwanted resonances in the mid frequencies. Multiple holes prevent air compression under the spider, eliminating harmful resonances and further improving midrange clarity. Additionally, the opening ensures optimal decompression of the air column inside the voice coil.

Semi-Pressed Pulp Cone for Superior Sound Performance
The cone, made from semi-pressed pulp with cotton fibers, was selected by the R&D team for its excellent acoustic and mechanical properties. Its low density and high mechanical damping contribute to an exceptionally smooth frequency response in all listening positions, delivering natural and detailed sound reproduction. Using innovative finite element calculation methods, the research team obtained an extremely rigid structure. This design allows the cone's vibration modes (the frequencies where the cone deforms, causing response irregularities) to be shifted towards higher frequencies, leaving the entire midrange free from distortion and irregularities.
