A 550-watt Pure Class D amplifier drives a new 10 inch CarbonAlloy™ active driver and a 12 inch down-firing passive radiator, delivering speed, depth, and dynamic headroom for both music and theater systems. \u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe S\/550 is the smallest of the four Serie S models and, in REL's words, identical in quality to its larger stablemates; it substitutes a 10 inch driver and a smaller amplifier. For listeners who want Serie S speed and depth without stepping up to a larger cabinet, the S\/550 is the perfect balance of power, speed, and refinement\u003c\/p\u003e\n\u003c!-- Shipping Notes (optional, remove if not needed) --\u003e\u003c!-- Key Features --\u003e\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e550-watt Pure Class D amplifier\u003c\/strong\u003e designed for continuous high output with stability and control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 inch CarbonAlloy™ active driver\u003c\/strong\u003e with redesigned suspension and carbon fiber cap for fast attack and natural decay.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 inch Carbon\/Carbon passive radiator\u003c\/strong\u003e extends response with authority to 19 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for both\u003c\/strong\u003e two channel music systems and multichannel home theater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStereo pairs and line arrays\u003c\/strong\u003e supported for scalable performance in larger spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Level Neutrik Speakon input\u003c\/strong\u003e preserves the sonic character of your main amplifier for seamless integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e.1\/LFE inputs\u003c\/strong\u003e on RCA and XLR for cinema systems, with simultaneous connection support.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless ready\u003c\/strong\u003e via the optional REL \u003ca href=\"\/products\/rel-airship-direct-wireless\"\u003eAirship Direct\u003c\/a\u003e receiver, which plugs into a dedicated connector on the rear panel, for flexible placement without long cable runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium finishes\u003c\/strong\u003e in Piano Black or Gloss White, with optional \u003cstrong\u003ePremium Wood Grille\u003c\/strong\u003e (natural grain and color variations are expected).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- Design --\u003e\n\u003ch5\u003eDesign\u003c\/h5\u003e\n\u003cp\u003eThe cabinet increases internal volume while remaining visually light. Horizontal strakes and elliptical returns frame integrated handles with a warm golden silver finish. Internal bracing controls resonance, badges recess into the grille cloth, and model markings are etched discreetly into the front rails for clean stacking in a line array. Front rail leveling adjusters simplify setup on uneven floors.

A carbon fiber center cap increases stiffness where it matters, sharpening transient attack and smoothing decay so notes fade naturally. The new suspension allows greater linear excursion, enabling higher output with less strain. A 12 inch down firing Carbon\/Carbon passive radiator complements the active driver to extend low frequency energy while maintaining control.\u003c\/p\u003e\n\u003c!-- Amplifier --\u003e\n\u003ch5\u003eAmplifier\u003c\/h5\u003e\n\u003cp\u003eThe Pure Class D module is rated at 550 watts RMS and has been tested at 600 watts continuous without signs of stress. Crest power exceeds the previous generation by fifty percent. Premium polypropylene capacitors in the input filters, borrowed from REL Reference designs, open the soundstage and improve transparency. REL’s second generation PerfectFilter™ optimizes very low frequency behavior so the S\/550 remains articulate and composed at depth.\u003c\/p\u003e\n\u003c!-- Integration and Connectivity --\u003e\n\u003ch5\u003eIntegration and Connectivity\u003c\/h5\u003e\n\u003cp\u003eREL’s 100 percent analog high level input connects to the speaker outputs of your main amplifier to carry its full sonic signature, which is a proven path to seamless blend with your mains. Low level stereo RCA and dedicated .1\/LFE on RCA and XLR support theater builds, and the inputs can be used in tandem for mixed music and cinema systems. Wireless operation is available with the optional Airship Direct receiver, which carries both the High Level and .1\/LFE signals, for installations where cabling is impractical.\u003c\/p\u003e\n\u003c!-- The Listening Room Difference --\u003e\n\u003ch5\u003eThe Listening Room Difference\u003c\/h5\u003e\n\u003cp\u003eWe are a third-generation, family-owned hi-fi shop in Chestertown, Maryland, known for service and trust rather than hype.
