Important Notes:

VOCE II System Integration Required: This crossover is specifically designed for use with Audison VOCE II speaker components. Optimal performance achieved when paired with AV 6.5 P II mid-bass, AV 3.0 II midrange, and AV 1.1 II tweeter. Using non-VOCE II components may result in impedance mismatches, frequency response irregularities, and suboptimal sound quality. Professional installation and system tuning recommended for proper component integration.

Bi-Amplification Capability: High-current switch enables independent amplification of woofer and tweeter sections for maximum control and power handling. When bi-amplifying, ensure amplifier channels are properly gain-matched and time-aligned. Mono-amplification (single amplifier driving all components) is also supported. Verify amplifier power ratings match speaker power handling specifications before connection.

Contour Controls Require Tuning: Mid-Contour and Hi-Contour controls must be adjusted based on speaker placement, vehicle acoustics, and listening position. Incorrect settings may cause frequency response peaks, dips, or poor imaging. Start with neutral settings and adjust incrementally using test tones and music reference tracks. Professional tuning with RTA (Real-Time Analyzer) recommended for optimal results.

High-Current Wiring Essential: Premium passive crossover requires high-quality speaker wire with adequate gauge for power handling. Use minimum 14 AWG (preferably 12 AWG) oxygen-free copper wire for all connections. Poor quality or undersized wiring increases resistance causing power loss, frequency response degradation, and potential component damage under high-current operation.

Proper Mounting and Heat Dissipation: Crossover components generate heat during operation, particularly resistors and inductors under high power. Mount crossover in well-ventilated location away from heat sources. Ensure adequate airflow and avoid enclosing in sealed compartments. Excessive heat degrades component performance and longevity.

Frequently Asked Questions

Q: What speakers is the AVCX 3P designed to work with?

A: The AVCX 3P is specifically engineered for Audison VOCE II component speakers. The optimal configuration pairs the AV 6.5 P II mid-bass (250 Hz low-pass), AV 3.0 II midrange (50 Hz - 2.5 kHz band-pass), and AV 1.1 II tweeter (2.5 kHz high-pass). The crossover's frequency points, component values, and contour controls are precisely matched to these drivers' characteristics. Using non-VOCE II speakers may result in impedance mismatches, frequency response irregularities, and suboptimal performance.

Q: What is bi-amplification and should I use it?

A: Bi-amplification means using separate amplifier channels for different speaker sections - in this case, one amplifier/channel for the woofer and another for the midrange/tweeter combination. The AVCX 3P's high-current switch enables this configuration. Benefits include independent power allocation, reduced amplifier stress, improved dynamic headroom, and better control over each frequency band. However, bi-amping requires careful gain matching and time alignment between amplifiers. For simpler installations, mono-amplification (single amplifier driving all components through the crossover) is fully supported and provides excellent results.

Q: How do I adjust the Mid-Contour and Hi-Contour controls?

A: Start with both controls in neutral position. The Mid-Contour adjusts the mid-bass response based on woofer placement - use the alternate position if woofer is door-mounted or requires frequency response compensation. The Hi-Contour adjusts the tweeter's high-pass crossover point based on tweeter position and angle - adjust if tweeter is significantly off-axis or requires integration refinement. Make one adjustment at a time, listening to familiar music tracks with strong mid-bass (kick drums) and high-frequency content (cymbals, vocals). Professional tuning with RTA measurements provides the most accurate results.

Q: What wire gauge should I use and where should I mount the crossover?

A: Use minimum 14 AWG oxygen-free copper speaker wire, with 12 AWG preferred for high-power systems. Keep wire runs as short as practical, maintaining consistent gauge from amplifier through crossover to speakers. Mount the crossover in a well-ventilated location protected from moisture and physical damage - common locations include under seats, in door cavities (if ventilated), or behind kick panels. Ensure adequate airflow around the crossover as passive components generate heat under high power operation. Avoid mounting near amplifiers, heat vents, or in sealed compartments.

Q: Can I use this crossover with active (DSP) processing?

A: The AVCX 3P is a passive crossover designed for use without active DSP processing. However, it can be integrated into systems using DSP for time alignment, equalization, and level matching, as long as the DSP's crossover functions are disabled or set to pass full-range signal to the passive crossover. Some advanced users employ DSP for bass management and overall system EQ while using the AVCX 3P for the three-way component speaker integration. For systems requiring active crossover control, consider Audison's bit amplifiers or processors with full active crossover capabilities instead.
