Features & Specifications



Definitive Technology Demand 17 Floor Standing Speakers – Black – Pair

The Definitive Technology Demand 17 loudspeakers are the discerning listener’s choice for smooth high-frequency reproduction, thundering lows, and three-dimensional imaging that fills your space with beautiful sound.

Breathtaking Musicality

D17 tower speakers are meticulously engineered with a laterally offset 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, and dual 6.5” carbon fiber bass woofers complemented by dual 10” side-firing passive radiators for a full-range, breathtakingly musical sonic performance.

Clear, Precise Highs

The Definitive Technology Demand 17 couples a laterally offset 1” Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens™. We offset the tweeters by 5°, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, exacting high-frequency performance and detailed soundstage.

Superior Midrange Detail

The D17’s 6.5” patented Balanced Double Surround System™ (BDSS) mid/bass driver provides greater excursion and output for superior midrange detail and punchier bass compared with other drivers of similar size.

Deeper, Cleaner Bass

The Definitive Technology Demand 17 custom-woven 6.5” carbon fiber woofer produces superior cone rigidity for deep, evenly extended bass notes while preventing distortion-causing cone deformation that can occur with less rigid materials.

Dual 10″ Passive Bass Radiators for visceral bass response

Twin integrated 8” passive bass radiators in each speaker produce extraordinary low-end extension for louder, lower, unforgettably clean bass performance.

Audiophile-Quality Crossovers for beautifully balanced audio

Demand Series crossovers are built with the latest premium audiophile-quality parts, including polypropylene metal-film capacitors and air-core inductors. These high-end components meticulously manage frequencies for clean and crystalline treble, refined and articulate midrange, and linear, low-distortion bass. This ensures that every detail comes through within a clear, balanced presentation that never sacrifices power on the Definitive Technology Demand 17 speakers.

Linear Response Waveguide for natural imaging

Our patented Linear Response Waveguide extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.

Flawless Home Cinema Audio

True audio enthusiasts are obsessive about all sound, not just their music. The meticulous attention to detail that enables the Definitive Technology Demand 17 Tower Speaker to beautifully reproduce music also enables it to flawlessly reproduce home theater audio.

Artistry to the eye and ear

Extruded aluminum front baffles capture a clean, modern aesthetic with a bead-blasted finish for a timeless look and feel to fit any décor. Each speaker is meticulously sanded and painted with five layers of premium gloss paint, then buffed to a near-mirror finish.
