The BLAUPUNKT HCS502 5.25 inch 2-way coaxial speaker is designed to reproduce mid-range and high frequencies in automotive audio systems. Combining a woofer cone and a coaxial tweeter in a single 5.25" (13.3 cm) driver, this unit fits standard factory mounting locations for easy replacement or aftermarket upgrade. It is intended to improve clarity, vocal presence and instrument detail for everyday driving and longer journeys without requiring changes to the vehicle's mounting points.
Advantages
The coaxial layout integrates a dedicated mid/bass cone and a high-frequency tweeter to provide balanced sound across the vocal and upper instrument range. Its 5.25" size makes it compatible with common factory openings, allowing straightforward installation as a direct swap. The speaker is engineered to deliver clearer imaging and improved midrange articulation compared with single-cone replacements, helping to enhance in-car listening quality while maintaining a compact profile.
Suitable for
- Factory replacement of 5.25" car speakers
- Aftermarket audio upgrades in compact and mid-size vehicles
- Improving vocal clarity and instrument detail in factory audio systems
- Daily driving and long trips where balanced mid/high reproduction is desired

How to use
Install the BLAUPUNKT HCS502 by removing the existing speaker grille and fasteners, disconnecting the factory speaker wiring, and fitting the HCS502 into the standard 5.25" opening. Reconnect the wiring observing polarity, secure the speaker with the original or supplied fasteners, and replace the grille or trim.

If needed, adjust the head unit or amplifier equalization to match listening preferences.
Usage recommendations
For best performance, use the speaker in systems where a dedicated tweeter crossover or factory crossover is present or retained. Avoid prolonged high-volume playback without adequate amplifier headroom to prevent distortion and to preserve speaker longevity.
