While its larger sibling, the S\/850, sets the ultimate benchmark, the S\/550 carries forward many of the same design innovations—ensuring the essence of Serie S is fully realized in a more compact form.\u003c\/p\u003e\n\u003cp\u003eThe results are remarkable: S\/550 offers lightning-fast transients, deep articulate bass, and tonal balance that breathes life into both music and film.

Everywhere you look, thoughtful details emerge—but the purpose is clear. This generation delivers the seemingly impossible: a larger cabinet that is lower, wider, and deeper, yet visually lighter.\u003c\/p\u003e\n\u003cp\u003eThe added internal volume gives drivers greater freedom and amplifiers improved efficiency, while updated internal bracing keeps cabinet resonances firmly under control. Subtler touches also make a difference, badges that disappear into the grille cloth, silver accents that rest quietly within the cabinet plane, and model numbers etched discreetly into the front rails, visible only when stacked in a Line Array.\u003c\/p\u003e\n\u003cp\u003eAn optional Premium Wood Grille adds warmth and individuality, while front-rail leveling adjusters ensure effortless setup, even on uneven floors. Together, these refinements reflect REL’s philosophy that great design is as much about thoughtful usability as it is about beauty and performance.\u003c\/p\u003e\n\u003ch2 class=\"mb-3 h3\"\u003eWhat's in the box\u003c\/h2\u003e\n\u003cdiv class=\"col-xl-11 lh-xl\"\u003e\n\u003cul\u003e\n\u003cli\u003eSerie S\/550 Subwoofer\u003c\/li\u003e\n\u003cli\u003ePower Cord\u003c\/li\u003e\n\u003cli\u003e32' Neutrik Speakon cable\u003c\/li\u003e\n\u003cli\u003eCloth Grille\u003c\/li\u003e\n\u003cli\u003eLine Array Mounting Hardware\u003c\/li\u003e\n\u003cli\u003eUser Manual and Warranty Information\u003c\/li\u003e\n\u003cli\u003e*The Premium Wood Grille is NOT included in your subwoofer purchase but is available for purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"REL Acoustics","offers":[{"title":"Piano Black Lacquer","offer_id":57921109918028,"sku":"RELS\/510-B","price":2499.17,"currency_code":"GBP","in_stock":true},{"title":"Piano White Lacquer","offer_id":57921109950796,"sku":"RELS\/510SUB-W","price":2499.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/44b2e5bf63d6fe8a026ec1d7c2d18935eba0888a_427456_v2__19096.jpg?v=1782732448","url":"https:\/\/www.stoneaudio.co.uk\/products\/rel-serie-s-s-550-subwoofer","provider":"Stone Audio","version":"1.0","type":"link"}
