Frequently Asked Questions

Q: What makes DCX 710.3 a "three-way" coaxial speaker?

A: DCX 710.3 features three separate driver components reproducing different frequency ranges: woofer handles bass frequencies (40Hz-midrange crossover), dedicated 60mm midrange driver reproduces critical vocal and instrumental frequencies, PEI dome tweeter extends high frequencies to 21kHz. True three-way design provides superior sound quality compared to traditional two-way coaxial speakers by dedicating separate components to bass, midrange, and treble ranges eliminating compromises inherent in simpler designs. Result: more accurate frequency reproduction, improved clarity, better dispersion, and involving emotional sound quality.

Q: Will DCX 710.3 fit my vehicle's factory 6x9" speaker locations?

A: DCX 710.3 measures 7x10" (181mm) which differs from 6x9" (6" x 9") dimensions. Verify exact factory speaker opening dimensions and mounting hole pattern before purchase. Some vehicles with 6x9" locations may accommodate 7x10" speakers with minor modification or adapter brackets—check vehicle-specific fitment information. DCX 710.3 mounting depth 110mm (4.3")—verify adequate clearance behind mounting surface. For guaranteed fitment, measure factory opening dimensions and compare to DCX 710.3 specifications or consult vehicle-specific speaker fitment guides.

Q: Can DCX 710.3 be powered by factory head unit?

A: Yes—DCX 710.3 4-ohm impedance compatible with factory and aftermarket head units. Exceptional 93dB sensitivity ensures excellent performance with factory head unit power output (typically 15-25W RMS). While DCX 710.3 capable of handling 150W continuous power for maximum performance with aftermarket amplification, efficient design delivers involving sound quality with factory systems. For best results: upgrade to quality aftermarket head unit or add dedicated amplifier providing 75-150W RMS per channel maximizing DCX 710.3 capabilities.

Q: What is TPU surround and why is it better?

A: TPU (Thermoplastic polyurethane) surround provides superior performance compared to traditional rubber or foam surrounds. Benefits: exceptional flexibility enabling linear cone excursion, superior durability resisting cracking and deterioration from temperature extremes, moisture resistance preventing degradation from humidity or water exposure, consistent performance across temperature range, long-term reliability maintaining flexibility over years. Traditional rubber surrounds harden and crack over time, foam surrounds deteriorate from UV exposure and moisture. TPU surround ensures DCX 710.3 maintains performance integrity throughout service life in demanding automotive environments.

Q: Does DCX 710.3 require external crossover network?

A: No—DCX 710.3 includes integrated crossover network built into speaker assembly. Crossover directs appropriate frequencies to woofer, midrange, and tweeter components ensuring proper frequency distribution without external components. Simply connect speaker wires to DCX 710.3 terminals—internal crossover handles frequency division automatically. Benefits: simplified installation, no external crossover mounting required, optimized frequency response, proper component protection. For advanced applications: DCX 710.3 can be upgraded with external active crossover and multi-channel amplification for ultimate performance and tuning flexibility.

Q: What is the difference between water-repellent pressed paper cone and polypropylene?

A: Water-repellent pressed paper cone provides superior sonic characteristics compared to polypropylene: better internal damping reducing cone resonances, natural tonal balance without synthetic coloration, smooth frequency response, lower distortion. Water-repellent treatment protects paper cone from moisture damage maintaining structural integrity in automotive door installations exposed to weather. Polypropylene cones offer moisture resistance but typically exhibit more coloration and resonances affecting sound quality. Hertz uses water-repellent treated paper combining natural sonic benefits with practical moisture protection for automotive applications.

Q: Can DCX 710.3 be installed in door locations?

A: Yes—DCX 710.3 suitable for door installation with 110mm (4.3") mounting depth accommodating most door panels with adequate clearance behind speaker. Water-repellent cone construction resists moisture damage from door panel exposure including weather seal leaks and humidity. Installation considerations: verify adequate mounting depth measuring from mounting surface to window mechanism, door frame, or obstacles, ensure proper speaker enclosure or door treatment for optimal bass response, seal door panel penetrations preventing moisture entry, secure mounting using all mounting points preventing vibration. Rear deck installation also suitable for vehicles with adequate deck depth and opening dimensions.
