Product Research
Features
Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.
4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The DB402's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Please enter your vehicle information to confirm fit.
Marine Certification: Polk speakers are marine certified, making them a good choice for boats in fresh water, convertibles, motorcycles, ATVs, and other applications where the speaker might get wet. Because they have coated steel baskets and the terminals and crossover components are not covered, we do not recommend using them in salt water environments.
The Polk Audio DB 402 replaces these items:
- polymer/mica composite woofer with butyl rubber surround
- 3/4" liquid-cooled silk/polymer composite dome tweeter
- frequency response: 85-22
- 000 Hz

The people at Crutchfield are top notch. I had trouble finding speakers for a 35 year old motorcycle, but your tech guys were very helpful and very thorough in their help. Thanks again.
