Audison APK690 6x9" 2-Way Component Speaker System

The Audison APK690 is a Prima Series 2-way component speaker system designed for vehicles with factory 6 x 9-inch door speaker locations. It combines AP 690 elliptical woofers, AP 1 tweeters, and dedicated APCX TW 690 passive crossovers. This configuration provides a practical upgrade path for vehicles that need separate high-frequency placement rather than a coaxial speaker.

Rated for 100 watts continuous and 300 watts peak power handling, the APK690 presents a 4-ohm load to the audio system. Its specified system frequency response is 40 Hz to 20 kHz, covering bass and midrange output from the wofer section along with high-frequency extension from the separate tweeters. The woofer sensitivity is rated at 95 dB SPL.

The AP 690 woofer uses a 25 mm pure-copper voice coil and a water-repellent treated paper cone. Its cone profile was developed with FEM simulation and optimized with Klippel R&D Scan Vibrometer measurements. A Triple Wave surround is used to support linear cone excursion, while the compact basket is intended to help with OEM-style door installations.

The AP 1 tweeter has a 26 mm diaphragm with a wide-roll surround and an acoustic lens. Audison specifies the lens to help compensate for in-car response effects in the 10 kHz to 13 kHz range associated with challenging OEM mounting locations. The separate tweeter arrangement gives installers flexibility to retain or improve factory high-frequency speaker positions.

Each system uses an APCX TW 690 crossover, which applies a 6 dB-per-octave high-pass filter at 3.3 kHz for the tweeter. The compact crossover includes a 0 dB or +3 dB tweeter-level setting for adjustment after installation. The APK690 can be used as part of a factory-radio upgrade or paired with a compatible 4-ohm aftermarket amplifier.

Key Features

• 6 x 9-Inch Component System: Separate woofers and tweeters support flexible vehicle-specific placement.
• 100W Continuous Handling: Supports systems rated up to 100 watts continuous power.
• Dedicated Passive Crossovers: APCX TW 690 networks manage tweeter filtering and level adjustment.
• Adjustable Tweeter Output: Choose 0 dB or +3 dB tweeter attenuation settings.
• Water-Repellent Paper Cone: Treated woofer cone is designed for door-speaker environments.
• Pure Copper Woofer Coil: 25 mm voice coil supports power handling and cone control.

Design & Installation

The AP 690 woofer uses a compact, abrasion-resistant and scratch-resistant coated basket, with the motor secured using damping epoxy adhesive. Its 90 x 32 x 15 mm woofer magnet and 25 mm voice coil are paired with a treated paper cone and Triple Wave surround. The AP 1 tweeter uses a 26 mm diaphragm, while the compact APCX TW 690 crossover measures 46.5 x 37.5 x 20.1 mm.

Confirm that the vehicle accepts a 6 x 9-inch elliptical woofer and has adequate mounting clearance before purchase. Install the AP 1 tweeters and AP 690 woofers through the supplied APCX TW 690 crossovers; the crossover's fast-on connectors are intended to simplify correct connections. Match the system to a compatible 4-ohm amplifier or speaker channel, and use the 0 dB or +3 dB tweeter setting to suit the final mounting location.
