REL S/550 Subwoofer

The 10-inch active driver handles the primary bass output, while the 12-inch down-firing passive radiator extends the low-frequency response. This combination allows the S/550 to produce deep, authoritative bass from a smaller cabinet footprint than a traditional ported design.

It is designed to excel at both. Because REL prioritizes speed and transient response, it provides the articulation needed for complex musical passages while maintaining the power and impact required for cinematic sound effects.

Yes, the S/550 is designed to support stereo pairs or even larger line arrays. Using two subwoofers can help smooth out room modes and provide a more balanced, immersive soundstage across your listening area.

The CarbonAlloy material is exceptionally stiff and lightweight, which allows the driver to start and stop very quickly. This results in tight, precise bass that doesn't 'smear' or lag behind the main speakers.

The S/550 is optimized for medium-sized rooms. Its 550-watt amplifier provides enough headroom to fill these spaces with clean, controlled low-end without overwhelming the room or sacrificing detail.
