Wool Pulp Cone Technology in 6x9" Format

Audiophile-Grade Material Selection

The ADCX6923 represents Audio Dynamics' commitment to tonal accuracy—bringing the same wool pulp cone technology found in their premium component systems to the practical 6x9" coaxial format. After countless listening hours examining materials from glass fiber to Kevlar to carbon fiber, Audio Dynamics chose wool pulp (paper-based) for its unmatched ability to deliver astonishing realism and detailed timbre across the harmonic spectrum.

• Natural Damping Characteristics — Wool pulp's fibrous structure provides inherent mechanical damping, eliminating resonance peaks and metallic coloration found in polypropylene or aluminum cones
• Harmonic Accuracy — Reproduces overtones and harmonics with exceptional fidelity, preserving the natural timbre of acoustic instruments and vocals
• Controlled Breakup Behavior — Progressive cone breakup extends usable frequency response smoothly without harsh resonances
• Warm, Natural Tonality — Organic sound signature eliminates listening fatigue during extended sessions

Why 6x9" Format Matters

The 6x9" driver size provides distinct advantages for rear deck and parcel shelf applications where space and output requirements exceed what 5.25" or 6.5" speakers can deliver:

• Increased Cone Area — 33% more surface area than 6.5" speakers translates to higher output and deeper bass extension
• Factory Fitment — Designed for common 6x9" rear deck locations in sedans, coupes, and SUVs
• Midbass Authority — Larger cone moves more air for impactful midbass punch that complements subwoofer output
• Rear-Fill Efficiency — High output capability fills rear cabin space without requiring extensive amplification

25mm Polymer Film Dome Tweeter

Smooth High-Frequency Extension

The ADCX6923's center-mounted 25mm (1-inch) polymer film dome tweeter provides clear, effortless high-frequency reproduction without the harshness common in budget 6x9" speakers.

• Polymer Film Dome — Lightweight diaphragm material extends high-frequency response while maintaining smooth tonality
• Minimal Protrusion — 1/4" (6mm) tweeter height reduces risk of damage in rear deck installations
• Mylar Capacitor Crossover — High-quality Mylar capacitor in tweeter circuit ensures clean frequency division
• Balanced Integration — Tuned to complement wool pulp cone's natural midrange character without artificial brightness

Dampened Steel Frame Construction

Engineered for Durability & Acoustic Performance

The ADCX6923 uses a dampened steel frame to provide structural rigidity while minimizing unwanted resonances that can color sound reproduction.

• Dampened Steel — Material treatment reduces basket resonance that causes coloration in cheaper stamped-steel designs
• Rubber Surround — Durable rubber surround provides longevity and consistent performance in automotive environments (superior to foam surrounds that deteriorate)
• 25.4mm Voice Coil — 1-inch voice coil diameter provides adequate power handling and thermal capacity for 100W RMS operation
• Shallow Mounting Depth — 3" (77mm) depth fits most factory rear deck locations without modification

Installation Considerations

Factory 6x9" Replacement

The ADCX6923 is engineered as a direct replacement for factory 6x9" speakers commonly found in rear decks, parcel shelves, and some door locations.

• Rear Deck Applications — Ideal for sedans and coupes with rear parcel shelf mounting locations
• SUV Installations — Works well in rear cargo area side panels or third-row locations
• Door Mounted 6x9" Locations — Some vehicles (trucks, older domestic models) use 6x9" door speakers
• Plug-and-Play — Integrated crossover eliminates need for external components; simple wiring to factory harness or amplifier

Power Requirements & Sensitivity

The ADCX6923's 88.44 dB sensitivity provides balanced efficiency—suitable for both factory head unit applications (25–35W RMS) and amplified systems (50–100W RMS per channel).

Recommended High-Pass Filtering

For optimal power handling and sound quality, Audio Dynamics recommends using an electronic high-pass crossover:

• 60 Hz @ 24 dB/octave — Best for deep integration with subwoofers; protects speakers from excessive low-frequency excursion
• 80 Hz @ 18 dB/octave — Balanced approach for most systems with 10" or 12" subwoofers
• 100 Hz @ 12 dB/octave — Suitable for compact subwoofer systems or maximizing midbass output from 6x9" drivers

Use Cases & Applications

Ideal For:

• Rear-Fill Applications — Tonally matches Audio Dynamics component front stages for cohesive system sound
• Factory System Upgrades — Massive improvement over factory paper cone 6x9" speakers without amplifier requirement
• Midbass-Focused Systems — Provides impactful midbass punch to complement subwoofer output
• Sedan & Coupe Rear Decks — Purpose-built for classic 6x9" rear deck mounting locations
