3-Way Configuration with Dual 8" Passive Radiators

The 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. 

1” Aluminum Dome Tweeter with 20/20 Wave Alignment Lens™

Coupled with the 20/20 Wave Alignment Lens™, 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 improved 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 to deliver a more precise center stereo image and eliminate undesirable symmetric diffraction off the corners of the front baffle.

BDSS™ (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 Waveguide™

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 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.

Premium Hi-Fi Crossover

Demand 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 tweeter, and signal linearity for the low-frequency reproduction, without compromising the midrange.
