How do the RPX525 perform on factory radio power?

• Works well with factory radios and modest aftermarket head units
• 90 dB sensitivity for efficient sound output
• 4-ohm impedance compatible with common OEM wiring

What sound characteristics can I expect from these 5.25-inch coaxials?

The microfiber paper cone yields natural midrange reproduction while the soft silk dome tweeter provides smooth, detailed highs. Together they offer a wide, balanced response suited to vocals, acoustic instruments, and modern production.

• Wide frequency coverage: 45–20,000 Hz for full-range replay
