Audison APK163 6.5" 3-Way Component Speaker Set

The Audison APK 163 is a 4-ohm, three-way component speaker system designed for upgrading factory car audio while retaining practical OEM-style installation options. It combines a 6.5-inch AP 6.5 woofer, 4-inch AP 4 midbass, and 1-inch AP 1 tweeter with dedicated passive crossover networks. This arrangement is suited to listeners who want greater frequency coverage and separation than a typical two-way component system.

With 125 watts continuous and 375 watts peak power handling, the APK 163 is intended for use with an appropriately matched aftermarket amplifier or a capable factory-powered upgrade. Its specified 50 Hz to 20 kHz frequency response covers bass, midrange, and treble duties across three separate drivers. The system's 4-ohm nominal impedance supports conventional car-audio amplification.

The AP 6.5 woofer uses a 32 mm pure-copper voice coil and a water-repellent pressed-paper cone to provide controlled low-frequency output. The AP 4 midbass extends the system's vocal and upper-midrange coverage, helping place more of the musical range in dedicated drivers. A 26 mm Tetolon-fiber AP 1 tweeter handles high frequencies and incorporates an acoustic lens intended for OEM grille installations.

Audison equips the APK 163 with separate compact crossovers for the woofer, midbass, and tweeter. This design helps simplify OEM replacement installations by avoiding the need to route additional crossover wiring through the vehicle door. The tweeter crossover also provides 0 dB and +2 dB level settings for adjustment based on tweeter position and grille placement.

The woofer and midbass use water-repellent treated paper cones, TPU surrounds, and compact baskets intended for shallow OEM locations. Their Triple Wave surround profile is engineered to support linear cone excursion, while the woofer uses high-current fast-on terminals with dual contacts for flexible connection. Grilles and crossover networks are included, making the APK 163 a complete passive three-way front-stage speaker package.

Key Features

• Three-Way Component Layout: Separate woofer, midbass, and tweeter cover dedicated frequency ranges.
• 125W Continuous Handling: Supports use with properly matched aftermarket amplification.
• Dedicated Passive Crossovers: Individual networks simplify integration of each speaker component.
• Tweeter Level Selection: Choose 0 dB or +2 dB output.
• Water-Repellent Paper Cones: Treated woofer and midbass cones suit vehicle-door environments.
• OEM-Focused Connections: Woofer fast-on terminals support quick, flexible wiring.

Design & Installation

The AP 6.5 woofer and AP 4 midbass use high-density-flux ferrite magnets, water-repellent pressed-paper cones, and TPU Triple Wave surrounds. Their compact baskets have an abrasion-resistant, scratch-resistant coating, while the woofer motor is secured with damping epoxy adhesive. The AP 1 tweeter uses a 26 mm Tetolon-fiber diaphragm and wide-roll surround.

Confirm that the vehicle has mounting positions for a 165 mm woofer, 100 mm midbass, and 26 mm tweeter before installation. Install each included crossover with its intended driver and use the specified passive crossover points rather than bypassing the networks. Select the tweeter crossover's 0 dB or +2 dB setting according to placement, particularly when the tweeter is mounted behind a restrictive factory grille.
