REL Acoustics Serie S Subwoofer

The S/510 is designed to be versatile, utilizing a 500-watt Class D amplifier that provides the speed required for musical transients and the raw power needed for cinematic impact. Its ability to integrate seamlessly with high-end speakers ensures that it enhances the soundstage for music while delivering the deep, controlled bass necessary for home theater dynamics.

The front-firing 10-inch active driver provides the punch and precision, while the 12-inch down-firing passive radiator extends the low-frequency output. This configuration allows the subwoofer to reach down to 20 Hz while maintaining a compact, manageable footprint.
