Definitive Technology Demand D15 high-performance tower speakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling.
1” Aluminum Dome Tweeter with 20/20 Wave Alignment LensTM
Coupled with the 20/20 Wave Alignment LensTM, Definitive Technology 1” aluminum dome tweeters deliver a clear, precise high frequency response. The 20/20 Wave Alignment Lens smooths high frequencies off the tweeter for improbe dispersion and a rich and balanced listening experience anywhere in your room.
Laterally Offset Tweeter Assembly
A unique sonic signature feature of the Demand Series, the tweeter is offset by .5’’ to deliver a more precise center stereo image and eliminate undesirable symmetric diffraction off the corners of the front baffle.
BDSSTM (Balanced Double Surround System) Midrange
Patented Double Surround mid-range provides greater linear excursion and output that results in superior mid-range detail and punchier bass compared to drivers of similar size.
Linear Response WaveguideTM
Patented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural midrange timbre and more precise imaging.
Newly Designed Carbon Fiber Woofers
This 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.
Extruded Aluminum Front Baffle
Clean, beautiful modern industrial design with an estrude 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.
