Its redesigned 10\" active driver and 12\" passive radiator deliver faster response, greater travel, and bass that is louder, richer, and more effortless than ever before.\u003c\/p\u003e\n\u003cp\u003eA wider, lower-profile cabinet enhances scale and presence, making the S\/550 feel larger than its footprint suggests. Compact in size but bold in performance, it redefines what a mid-size subwoofer can achieve.\u003c\/p\u003e\n\u003cp\u003eEach unit comes finished in Piano Black or White Gloss with a matching cloth grille (black or white). For an even more refined look, a premium sculpted wood grille is available. As with all Serie S models, the S\/550 is Airship Direct™ ready, ensuring wireless freedom without sacrificing speed or detail.\u003c\/p\u003e\n\u003cp\u003eAs the entry point into Serie S, the outgoing S\/510 carried the speed and agility of Serie T\/X, but with added bass extension. This involved the use of lighter and stiffer drivers and faster input filters, and a lot of work went into getting this elusive combination perfect. We're excited that the S\/550 is even faster, lighter, and more powerful. \u003c\/p\u003e\n\u003ch4\u003eWhat’s New in Serie S\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFaster, lighter drivers with carbon-fibre refinements\u003c\/li\u003e\n\u003cli\u003eRedesigned passive radiators with greater travel\u003c\/li\u003e\n\u003cli\u003eAmplifiers with expanded headroom and control\u003c\/li\u003e\n\u003cli\u003eWider, lower cabinets for improved scale and presence\u003c\/li\u003e\n\u003cli\u003eNew grille options: cloth (standard) or sculpted premium wood (optional)\u003c\/li\u003e\n\u003cli\u003eAirship Direct™ wireless compatibility across the range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDrivers:\u003c\/strong\u003e 10\" CarbonAlloy active, 12\" carbon-infused passive\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmplifier:\u003c\/strong\u003e 550 W class-D\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCabinet:\u003c\/strong\u003e Wider, lower profile design for improved presence\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow Frequency Extension (-6 dB):\u003c\/strong\u003e 19 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWireless:\u003c\/strong\u003e Airship Direct™ ready\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrilles:\u003c\/strong\u003e Standard cloth (black or white); optional premium wood grille\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFinishes:\u003c\/strong\u003e Piano Black, White Gloss\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WHD):\u003c\/strong\u003e 15.7\" x 16\" x 18.25\" (400 x 410 x 464 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 70 lb.
