\nDemand D15 \n \nDefinitive Technology Demand D15 high-performance tower speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling. Ideal for small to medium rooms, the Demand D15 leverages exclusive technologies of the Demand Series such as a 1” annealed aluminum dome tweeter and BDSS™ midrange/woofer sections, new carbon fiber woofers and dual side-firing passive radiators. The Demand D15 is fully equipped to deliver smoother high-frequency reproduction and three-dimensional imaging from the most technically advanced and beautifully designed premium tower speaker. Demand more from your Hi-Fi and home theater experience. \n \n3-WAY CONFIGURATION WITH DUAL 8″ PASSIVE RADIATORS \n \nThe Demand D15 tower speakers feature an exclusive 3-way driver configuration with a 1” annealed aluminum dome tweeter, a 5.25” BDSS™ midrange woofer, a dual 5.25” carbon fiber bass drivers complement with a dual 8” side firing passive radiator configuration for a full range, room-filling sonic performance. \n \n1″ ANNEALED ALUMINUM DOME TWEETER \nWITH 20/20 WAVE ALIGNMENT LENS™ AND LATERALLY OFFSET TWEETER ASSEMBLY \n \nDefinitive Technology sets the standard of minimalist, thoughtful design that serves to better the sound. Proper tweeters must excel in three ways: they must be stiff, light, and well-damped in order to minimize their material characteristics that will affect high-frequency reproduction. Aluminum is naturally stiff and lightweight, meeting the first two requirements. To achieve the third, Definitive Technology tweeters undergo an annealing (heat treating) process to shape and soften the material, thereby providing the necessary material damping. \n \nCoupled with the 20/20 Wave Alignment Lens™, Definitive Technology 1” aluminum dome tweeters deliver a clear, precise high frequency response and the 20/20 Wave Alignment Lens smooths high frequencies off the tweeter for improved dispersion and a rich and balanced listening experience anywhere in your room. A unique sonic signature feature of the Demand Series, the tweeter is offset to deliver a more precise center stereo image and eliminate undesirable symmetric diffraction off the corners of the front baffle. \n \nBDSS™ MIDRANGE/WOOFER \nBALANCED DOUBLE SURROUND SYSTEM \n \nPatented Double Surround mid-range provides greater linear excursion and output that results in superior mid-range detail compared to drivers of similar size. \n \nLINEAR RESPONSE WAVEGUIDE™ \n \nPatented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural mid-range timbre and more precise imaging. \n \nNEWLY DESIGNED CARBON FIBER WOOFERS \n \nThis new addition to the sonic signature of the Demand Series tower features a dedicated woofer section for low frequency reproduction. Carbon fiber offers greater rigidity to the cone for deeper bass notes, while preventing cone distortion that can occur with other less rigid materials. Carbon fiber is a strong but light material, ideal for sound reproduction. It ensures that the woofers are sturdy yet light, able to handle higher excursion without deforming and provides deeper, clean low frequency. \n \nEXTRUDED ALUMINUM FRONT BAFFLE \n \nClean, beautiful modern industrial design with an extruded Aluminum front baffle bead blasted finish that provides a timeless look and feel that fits any décor. Lightweight, durable and recyclable, aluminum is truly the metal of a modern lifestyle. \n \nPREMIUM HI-FI CROSSOVER \n \nDemand Series crossovers integrate the latest in design and premium Hi-Fi quality parts. Polypropylene metal-film capacitors and air-core inductors deliver low distortion, high-clarity circuits for the circuits for the tweeter, and signal linearity for the low frequency reproduction, without compromising the midrange. \n \nDESIGNED IN CALIFORNIA \n \nOur Design Studio is located in California, where technology and innovation meet entertainment. It goes beyond the idea of a centralized location — it’s a cultural mindset that’s the Definitive Technology wellspring for creativity and inspiration. \n \n5-layer painted high-gloss black cabinet \n \nHand-crafted to blend seamlessly with your lifestyle, with a near-mirror finish \n \nAcoustically Transparent Magnetic Grille \n \nGrilles can be removed easily when you want to enjoy looking at them fully uncovered while ensuring natural, uncolored sound when placed on the speaker \n
