This allows the driver to accelerate and decelerate with remarkable speed, faithfully tracking the complexities of the audio signal. Working in concert is a downward-firing 12-inch SuperProgressive™ passive radiator, crafted from lightweight yet rigid carbon fibre. This combination empowers the S\/850 to produce profoundly deep and powerful low frequencies while crucially maintaining the speed and articulation necessary to integrate invisibly with high-performance main loudspeakers, thus creating a truly cohesive and full-range sound field.\u003c\/p\u003e\n\u003ch5\u003eCommanding Power: The NextGen5 Amplifier\u003c\/h5\u003e\n\u003cp\u003eTasked with driving this sophisticated driver system is the formidable NextGen5 Class D amplifier, rated conservatively at 850 watts (RMS).

It delivers the instantaneous current required to manage the long excursions of the active driver with unwavering precision. This meticulous control results in bass that is not only deep and impactful but also astonishingly detailed, textured, and free from smearing or overhang. It reveals the subtle nuances hidden within the lowest musical octaves and the most complex cinematic sound effects.\u003c\/p\u003e\n\u003ch5\u003ePerfect Integration: High Level Input \u0026amp; PerfectFilter™\u003c\/h5\u003e\n\u003cp\u003eA hallmark of REL design is the High Level Input, and the S\/850 employs it to perfection. By connecting directly to your main amplifier's speaker outputs, the S\/850 receives the identical sonic signature—the same signal, including the amplifier's character—as your main speakers. This ensures unparalleled tonal consistency and perfect timing integration. REL’s proprietary PerfectFilter™ technology further refines this connection, specifically tailored to complement the sonic characteristics of modern, high-end loudspeakers. This results in a seamless blend, where the S\/850 extends the bass response naturally, enhancing the overall soundstage width, depth, and openness without drawing attention to itself.\u003c\/p\u003e\n\u003ch5\u003eBuilding the Ultimate Bass Structure: Line Array Capability\u003c\/h5\u003e\n\u003cp\u003eWhile a single S\/850 delivers truly reference-calibre performance, its design anticipates the pursuit of ultimate bass reproduction.

This design uniquely marries the rich, high-current delivery of a traditional Class A\/B monoblock input stage with the cool-running efficiency of a Linear Class D output stage. This \"best-of-both-worlds\" approach, anchored by a massive 15-pound power transformer, creates a foundation of high-current performance that can sustain peaks of over 1,250 watts with ease. The result is bass that is louder, cleaner, and more controlled than any previous medium-chassis REL.\u003c\/p\u003e\n\u003ch5\u003eEngineered for Line Array Supremacy\u003c\/h5\u003e\n\u003cp\u003eWhile a single Carbon Special Black Label is a formidable performer, it was truly engineered to excel in stereo pairs and, ultimately, in towering vertical Line Arrays. The cabinet is designed to be a building block, with thick internal aluminum slabs anchoring its stainless steel handles for safe and secure stacking. REL supplies precision mechanical couplers that securely lock units together, ensuring perfect stability. A Line Array of Carbon Special Black Labels delivers a floor-to-ceiling sense of authority and scale that rivals the world’s finest and most expensive audio systems.\u003c\/p\u003e\n\u003ch5\u003eAcoustic Elegance: The Premium Wood Grille\u003c\/h5\u003e\n\u003cp\u003eThe Carbon Special Black Label is as beautiful as it is powerful.
