With a frequency response reaching down to 22Hz and a maximum output of 114dB, the Kube 12 MIE is built for larger rooms and home cinema or hi-fi systems where the deepest, most authoritative bass performance is required. Despite its increased driver size, the Kube 12 MIE retains the same sealed cabinet design and contemporary aesthetic as the rest of the Kube range, blending seamlessly into any room's décor whilst delivering substantially greater low-frequency depth and impact.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eMusic Integrity Engine \u0026amp; Intelligent Bass Extension\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eAt the heart of the Kube 12 MIE is KEF's proprietary Music Integrity Engine (MIE) — a suite of DSP algorithms that ensures every component of the subwoofer works in perfect harmony. The included iBX Intelligent Bass Extension technology dynamically extends bass depth, delivering deeper and more precise low-frequency reproduction at any listening level, from quiet background music to full home cinema impact.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFront-Firing Long-Throw Driver\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe Kube 12 MIE features a front-firing long-throw driver with a large cone area and high excursion capability, delivering the most powerful low-frequency output in the Kube range.

Three room position EQ presets ensure excellent performance regardless of where the subwoofer is placed in the room, removing the guesswork from positioning. Multiple power modes provide further convenience and flexibility: Auto Wake Up detects incoming audio signals for instant readiness, Always On mode keeps the subwoofer permanently ready to play, and 12V Trigger provides automatic wake-up in conjunction with compatible AV equipment.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal\"\u003eKEF Kube 12 MIE Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e12\" Front-Firing Long-Throw Driver:\u003c\/strong\u003e The largest driver in the Kube range, delivering the deepest bass extension and highest output for maximum low-frequency impact.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e300W Class-D RMS Amplifier:\u003c\/strong\u003e Efficient, cool-running amplification for unprecedented control and reliable sustained performance.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMusic Integrity Engine (MIE):\u003c\/strong\u003e Proprietary KEF DSP ensures every subwoofer component works in perfect harmony.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eiBX Intelligent Bass Extension:\u003c\/strong\u003e Dynamically extends bass depth for deeper, more precise low-frequency performance at any listening level.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e22Hz Low-Frequency Extension:\u003c\/strong\u003e The deepest bass response in the Kube range, for larger rooms and the most demanding systems.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e114dB Maximum Output:\u003c\/strong\u003e The highest output capability in the Kube range for maximum impact and headroom.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSealed Cabinet Design:\u003c\/strong\u003e Facilitates optimal placement flexibility within the room.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eContemporary, Elegant Design:\u003c\/strong\u003e Blends seamlessly with any room's décor despite its larger driver size.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eKW1 Wireless Ready:\u003c\/strong\u003e Optional wireless subwoofer adapter kit (sold separately) for cable-free placement flexibility.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e3 Room Position EQ Presets:\u003c\/strong\u003e Ensures excellent performance regardless of subwoofer placement within the room.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMultiple Power Modes:\u003c\/strong\u003e Auto Wake Up, Always On and 12V Trigger for flexible, convenient operation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVersatile Connectivity:\u003c\/strong\u003e KEF SmartConnect, RCA phono inputs, speaker level inputs and KW1 expansion port.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e 40Hz–140Hz plus LFE setting for precise integration with any AV or hi-fi system.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eIdeal for Larger Rooms:\u003c\/strong\u003e Maximum bass depth and output for the most demanding movies, music, TV and gaming setups.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"KEF","offers":[{"title":"Default Title","offer_id":57317173395829,"sku":"KEFKUBE12MIE","price":799.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/WEBKEF00265_KUBE12MIE_1.webp?v=1782468440","url":"https:\/\/www.audiovolt.co.uk\/products\/kef-kube-12-mie-300w-active-subwoofer-gloss-black","provider":"Audio Volt ","version":"1.0","type":"link"}
