The system includes separate 5.25" woofers and 0.75" silk dome tweeters with external crossovers that direct frequencies to the proper drivers for seamless performance. Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance.
Universal Installation Compatibility
Built marine tough and designed for a universal fit, DB+ series power the soundtrack of your ride wherever life takes you, on the road, the trail, the waves—you name it. The zero-tweeter protrusion design ensures that your factory grilles reinstall seamlessly, while the included mounting options accommodate both flush and surface tweeter installations.
Marine-Grade Durability
Each speaker has a non-corrosive plastic grille, a polypropylene UV tolerant cone, waterproof inner and outer surrounds, and stainless steel mounting hardware, ensuring that they are fully protected against the elements. Waterproof surrounds completely block dirt, liquid, and grime from entering the speaker housing—all designed to maximize longevity of the speaker.
Dynamic Balance is a proprietary Polk Audio technology that uses laser imaging to determine the optimal combination of speaker materials that creates the least amount of resonance. Eliminating resonance in speakers yields a wide, smooth response and reduced distortion. This ensures crystal-clear audio reproduction across all frequencies, eliminating the harsh sounds that plague inferior speakers.

What makes the DB5252 different from regular car speakers?
The DB5252 features marine certification with an IP56 waterproof rating, meaning it's tested for salt-fog, UV exposure, and humidity resistance. The Dynamic Balance technology utilizes laser imaging to eliminate resonance, while the component design, featuring separate tweeters and crossovers, provides superior sound staging compared to coaxial speakers. The marine-grade construction ensures longevity in harsh environments.
Can I install these speakers in my boat or ATV?
Absolutely. The DB5252 is specifically marine certified and designed for installation in cars, boats, motorcycles, and all-terrain vehicles (ATVs). The IP56 rating protects against water and dirt ingress, while the UV-resistant materials prevent degradation from sun exposure. The stainless steel mounting hardware is resistant to corrosion in marine environments.
Do I need an amplifier to power these speakers?
While an aftermarket head unit can power the DB5252, they truly shine when paired with an amplifier. With 100W RMS power handling per speaker, a quality amplifier will unlock their full potential for dynamic bass and clear highs. The 4-ohm impedance and 91dB sensitivity make them efficient and compatible with most amplifiers.
How difficult is the installation process?
Installation is designed to be straightforward with universal fit dimensions. The speakers drop into standard 5.25" openings, while the tweeters offer multiple mounting options including flush, surface, and factory locations. The included crossovers mount easily, and all necessary hardware is provided. Basic tools and wiring knowledge are recommended.
What's included in the complete system?
Each DB5252 system includes two 5.25" woofers with attached grilles, two 0.75" silk dome tweeters, two external crossover networks, multiple tweeter mounting cups (flush and surface), all mounting hardware, speaker cables, and a comprehensive installation manual with wiring diagrams.
What vehicles are these speakers compatible with?
The DB5252 fits any vehicle with standard 5.25" speaker openings, including most cars, trucks, boats, motorcycles, and ATVs. The 4.76" cutout diameter and mounting depth specifications ensure compatibility with factory locations. The universal design accommodates various mounting scenarios with the included hardware.
Can I adjust the sound balance between woofer and tweeter?
Yes, the external crossovers feature a three-position tweeter attenuation switch (0dB, +3dB, +6dB) that allows you to adjust the tweeter output level. This enables fine-tuning of the tonal balance to match your preferences and compensate for different vehicle acoustics or installation positions.
