The Audison Voce II AV 6.5 S II is a 6.5" slim woofer set rated at 125w RMS, part of Audison's Voce II range and designed for 2-way door installations.
Key specifications
- Size: 6.5"
- Power handling: 125w RMS
- Voice coil: 1.4" (36mm) CCAW (Copper Clad Aluminum Wire)
- Basket: Die-cast aluminium with magnet cover
- Cone: Semi-pressed pulp with cotton fibres
- Surround: High excursion butyl rubber
- Connectors: OEM-style and FASTON terminals
The AV 6.5 S II delivers smooth, natural sound with strong tonal balance and easy integration. Its electro-acoustic design ensures a controlled frequency response and consistent off-axis performance, supporting a coherent sound stage in typical door applications. It works well with simple crossover solutions, including gentle filtering slopes, enhancing low and mid-bass response while preserving clarity. The OEM-style connector is compatible with FASTON terminals for seamless integration into factory systems. The optimised motor structure minimises distortion for clean, controlled performance, making the AV 6.5 S II a reliable and flexible choice for high-quality 2-way systems.
Features
- 1.4" (36mm) CCAW voice coil: maximises excursion capability and heat dissipation, allowing the driver to handle 125w RMS with powerful bass free from dynamic compression at high volumes.
- Low inductance design: optimises upper midrange (2–3 kHz) reproduction for clearer vocals and instruments, via an aluminium shorting ring built into the motor.
- Oversized magnetic assembly: provides thermal stability and optimal dynamic reserve in any listening condition.
- FEM-optimised magnetic circuit geometry: concentrates the magnetic field on the coil for precise, dynamic sound.
- Semi-pressed pulp cone with cotton fibres: combines rigidity and lightness for wide frequency response and clean midrange reproduction.
- Die-cast aluminium basket with magnet cover: enhances heat dissipation, reduces turbulent airflow, and ensures maximum rigidity during prolonged use.
- High excursion butyl rubber surround and optimised spider: ensures linearity and cone control, reducing distortion during intense excursions.
- Installation flexibility: OEM-style and FASTON connectors included; comes with two adhesive Audison logos.

About the Audison AV 6.5 S II
From our tech experts at CEN
The Audison Voce II AV 6.5 S II is a 6.5" (165mm) slim woofer rated at 125w RMS, from Audison's Voce II range and designed for 2-way door installations. It runs at 4 ohm with a CCAW voice coil and semi-pressed pulp cone, covering 50–5500 Hz at 91 dB sensitivity. A separate tweeter is needed to complete the system.
Who it suits
This woofer suits drivers who want natural, detailed bass and midrange in door positions where mounting depth is tight. Its slim profile and OEM-compatible connectors make it a straightforward upgrade. Those who prefer a complete 2-way kit with tweeter and crossover included may consider the Audison Prima APK 165.
Our tech experts advise
The AV 6.5 S II fits a standard 165mm cut-out and operates at 4 ohm, so check your amplifier's impedance rating before fitting. Both OEM-style and FASTON connectors are included, easing connection to factory wiring. A crossover point in the 2–3 kHz range suits this driver well. Installation is priced per vehicle; visit our Nottingham fitting page to arrange.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: What is the power handling of the Audison AV 6.5 P II?
A: The AV 6.5 P II is rated at 150 W continuous (RMS) and 300 W peak, with a 4 ohm nominal impedance and 3.1 ohm minimum impedance.
Q: Do the AV 6.5 P II woofers need a low-pass filter?
A: Often not. The woofer rolls off naturally at off-axis positions, which removes the need for a low-pass filter in most door installations. A gentle 6 dB/octave filter can be used to enhance low and mid-bass.
Q: What connectors do the AV 6.5 P II woofers use?
A: They have both an OEM-style automotive connector and traditional Faston connectors, and a plug and play cable is included in the box along with a fixing kit and Audison badges.
