THX® Certified Select for medium-sized rooms, it’s engineered to deliver powerful dynamics, precise dialogue, and immersive surround effects with the refined detail KEF is known for. At the heart of the design is KEF’s 12th-generation Uni-Q driver array, which behaves like a single point source to widen the listening “sweet spot” and keep sound consistent across more seats. It also features KEF’s breakthrough Metamaterial Absorption Technology (MAT™) to reduce unwanted sound from the rear of the driver for cleaner, more natural high frequencies. A sleek Ultra-Thin Bezel (UTB) and paintable magnetic metal grille help it disappear into the wall—so you can hide the speaker, not the performance.\u003c\/p\u003e \u003ch4\u003eWhat It's Good At:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003eTrue theatre sound at home with THX® Certified Select performance tuned for medium-sized rooms\u003c\/li\u003e \u003cli\u003eClearer, cleaner high frequencies thanks to MAT™ absorbing unwanted sound for improved detail\u003c\/li\u003e \u003cli\u003eWider, more even coverage from the Uni-Q point-source design for a larger sweet spot\u003c\/li\u003e \u003cli\u003eTight, low-distortion bass powered by dual long-throw 120mm bass drivers\u003c\/li\u003e \u003cli\u003eBalanced, accurate sound from a 3-way design with optimized crossover networks\u003c\/li\u003e \u003cli\u003eSeamless in-wall aesthetics with an Ultra-Thin Bezel and paintable magnetic metal grille\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eKEF Ci3120QLM-THX Full Specifications:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Ci3120QLM-THX\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Q Series\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFrequency Response Range:\u003c\/strong\u003e 50Hz – 20kHz\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFrequency Response Remark:\u003c\/strong\u003e (±6dB) open-backed\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 42Hz – 20kHz\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 89dB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNominal Impedance:\u003c\/strong\u003e 4Ω\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNominal Coverage:\u003c\/strong\u003e 150°\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaximum SPL:\u003c\/strong\u003e 105dB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDrive Units:\u003c\/strong\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eLF:\u003c\/strong\u003e 2 × 120mm (4.75 in.)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMF:\u003c\/strong\u003e 100mm (4 in.)

Cut carefully, run speaker wire from your amplifier\/AVR to the opening, connect the wiring, and secure the speaker per the manual. Finish by fitting the grille and painting if desired; if you’re unsure about tools, wiring, or wall conditions, a professional installer is recommended.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eAre in-wall speakers a good choice compared to traditional box speakers?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eIn-wall speakers are ideal when you want high-quality sound with a clean, space-saving look. They reduce visual clutter and blend into the room, but placement is permanent once installed and installation takes more work than placing freestanding speakers. KEF’s Uni-Q design helps maintain consistent sound across the room, making in-wall setups especially rewarding in multi-seat spaces.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat should I look for in the best in-wall speakers for a home theatre?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003ePrioritize wide, even dispersion for multiple seats, clarity for dialogue, and strong dynamics for movie impact—then match the speaker’s performance level to your room size. Technologies like Uni-Q (for point-source imaging) and MAT™ (for reducing unwanted sound) help improve realism and detail. THX certification is also a strong indicator that the speaker is built to meet cinema-style performance targets.\u003c\/dd\u003e \u003c\/dl\u003e \u003ch4\u003eKEF Ci3120QLM-THX Downloads:\u003c\/h4\u003e \u003cp\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/KEF-Ci3120QLM-manual.pdf\" title=\"KEF Ci3120QLM-THX Manual\"\u003eKEF Ci3120QLM-THX Manual\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/KEF-Ci3120QLM-Specs-Sheet.pdf\" title=\"KEF Ci3120QLM-THX Specifications Sheet\"\u003eKEF Ci3120QLM-THX Specifications Sheet\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/ProductDrawing_Ci3120QML1.pdf\" title=\"KEF Ci3120QLM-THX Drawing\"\u003eKEF Ci3120QLM-THX Drawing\u003c\/a\u003e\u003c\/p\u003e","brand":"KEF","offers":[{"title":"Default Title","offer_id":62685685055647,"sku":"KEF-CI3120QLM-BLK","price":1299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0495\/6910\/4031\/files\/ff0f6402-be58-4418-96e6-ef506da9b138.jpg?v=1770936937","url":"https:\/\/listenup.com\/products\/kef-ci3120qlm-thx-in-wall-speaker","provider":"ListenUp","version":"1.0","type":"link"}
