The Demand D15 and D17 Tower Speakers Alongside D5C Center Channel Deliver Full-Range, Room-Filling Sound and Elegant Styling for Enthusiasts Seeking a Premium Listening Experience


Vista, Calif. (Jan. 7, 2020)—Today at CES 2020 taking place from January 7-10 in Las Vegas, Definitive Technology announced the Demand Series High-Performance Tower Speakers and center channel, adding to the celebrated Demand Series speaker range. The Demand D15 and Demand D17 towers and the D5C center are beautifully designed and employ advanced materials like carbon fiber woofers and annealed aluminum tweeters to deliver an unrivaled room filling sound, smooth high-frequency reproduction and precise imaging for a superior listening experience.


“Definitive Technology introduced the Demand Series in 2017 with three bookshelf speakers, which were warmly received in the market for their graceful design and highly accurate reproduction. Since then, we’ve been busy designing two new tower speakers and a center channel built on the principles of the original Demand Series bookshelf speakers,” said Michael Greco, category director Loudspeakers at Sound United. “We maintained the same level of craftmanship and material quality in designing and developing the line. Listeners will see familiar technologies, including the 20/20 Wave Alignment Lens™, BDSS and Linear Response Waveguide. However we also added newly designed dual carbon fiber bass drivers and dual side-firing passive radiators to the towers, which deliver some of the smoothest, most accurate and rich reproduction of any tower on the market in its price range. The center channel is the perfect addition to the line for home theater aficionados.”


The Demand Series D15 and D17 tower speakers feature an annealed 1-inch aluminum dome tweeter, which is laterally offset and coupled with a 20/20 Wave Alignment Lens. This allows for more precise imaging by eliminating undesirable symmetric diffraction from the corners of the front baffle, resulting in a refined and balanced listening experience. Definitive Technology’s patented Balanced Double Surround System (BDSS™) midrange/woofer promotes greater excursion and delivers superior mid-range detail and punchier bass in comparison to competing drivers of a similar size. In addition, a linear response waveguide extends both on-and off-axis frequency response, while improving dispersion for more natural mid-range timbre and precise imaging. 


The tower speakers boast a patented 5.25-inch and 6.5-inch mineral-polymer BDSS midrange/woofer, respectively, for superior and punchy mid-range detail. New to the Demand Series, each tower features dual 5.25-inch and 6.5-inch carbon fiber bass drivers alongside dual 8-inch and 10-inch side firing passive radiators. The new dual integrated side-firing passive radiators produce extended low-frequency reproduction from a smaller enclosure design. Definitive Technology also added a larger spider to increase linearity for deep, tight and clean bass response. 


The D5C center channel perfectly complements the Demand Series tower and bookshelf speakers to create a truly immersive home cinema experience. The two-way center leverages dual 5.25-inch mid-range drivers and 1-inch annealed aluminum dome tweeter with the same Wave Alignment and Linear Response Waveguide to ensure incredibly accurate and full-sounding audio.


In staying true to Definitive Technology’s class-leading industrial design, the Demand Series boast an incredibly clean, modern look with a substantial bead-blasted aluminum baffle that exudes timelessness and effortlessly blends into any décor. With artisan-quality details, each cabinet is meticulously sanded, painted with five layers of premium gloss paint and buffed to a near-mirror (Level 6) finish, resulting in a harmony of understated sophistication and uncompromising quality. Each monitor’s acoustically transparent magnetic black grilles provide natural, uncolored sound and can be easily removed for when the speakers are meant to be shown off. All three additions to the Demand Series line come in both Piano Black and White colorways to match any listening environment.


The new Definitive Technology Demand Series tower speakers will be on display at CES 2020 in the Venetian Hi-Fi Suites, room 29-105 and are immediately for purchase at national retailers including Magnolia inside Best Buy, Crutchfield and other fine retailers nationwide and regionally. Pricing for the Demand Series includes, D15: $1699.00/each, D17: $2299.00/each and D5C $799.00/each.
