What Makes a 4-Way Speaker Better?
A 4-way coaxial design divides audio frequencies among multiple drivers.
The Jensen JS6904 includes:
- Woofer for bass frequencies
- Midrange driver for vocals
- Two dedicated tweeters for high frequencies
This design helps improve:
- Frequency separation
- Vocal detail
- High-frequency clarity
- Overall soundstage
Compared to many stock speakers, the result is noticeably more detailed and balanced sound.
Enhanced Vocal Clarity
One of the standout features of the JS6904 is its 58mm Mylar balanced dome midrange.
Why does this matter?
The midrange handles:
- Vocals
- Guitars
- Piano notes
- Instrument detail
- Speech clarity
Because much of your music lives in the midrange frequencies, upgrading this portion of the audio spectrum often provides the biggest improvement in perceived sound quality.
Drivers can expect:
- Cleaner vocals
- Better instrument separation
- Improved overall detail
CLEAR 4-WAY AUDIO & EASY INSTALL – The 4-way design provides a much wider soundstage with wealthy detail. Dimensions include a 6” x 8.58″ cutout diameter, 3.07” top mounting depth, and 3.54” bottom depth.
ENHANCED VOCAL CLARITY – Equipped with a 58mm Mylar balanced dome midrange, these speakers sharpen midrange frequencies to verify vocals and instruments are crystal clear and freed from distortion.
Dual Piezo Tweeter Design
The dual 20mm piezo tweeters help extend high-frequency response.
Benefits include:
- Crisp highs
- Better cymbal detail
- Increased audio clarity
- Wider soundstage
This helps eliminate the dull, muffled sound often associated with aging factory speakers.
Strong Performance Without an Amplifier
One reason many drivers choose coaxial speakers is simplicity.
The JS6904 performs well when connected to:
Factory Head Units
Benefits include:
- Easy installation
- Immediate sound improvement
- No additional equipment required
Aftermarket Radios
Drivers can enjoy:
- Higher volume levels
- Improved sound quality
- Better overall performance
While amplification can help, it’s not required to enjoy these speakers.
Frequency Response Range
The 50Hz-20kHz frequency response covers most of the audible spectrum.
This allows the speakers to reproduce:
- Bass frequencies
- Midrange detail
- Treble information
Although a dedicated subwoofer will always outperform a full-range speaker for deep bass, the JS6904 provides a balanced listening experience on its own.
Installation Considerations
Before purchasing, verify available mounting space.
Speaker Dimensions
| Measurement | Size |
| Cutout Diameter | 6″ x 8.58″ |

Depending on the vehicle, adapter brackets or wiring harnesses may be required.

- Daily drivers
- Budget audio upgrades
- Older vehicles

- SUVs
- Factory stereo replacements
It’s especially appealing for drivers who want better sound without investing in a complete aftermarket audio system.
