The D17 tower speaker features an exclusive 3-way driver configuration with a 1” annealed aluminum dome tweeter, a 6.5” BDSS™ midrange woofer, and dual 6.5” carbon fiber bass drivers, complemented by dual 10” side-firing passive radiators, for a full-range, room-filling sonic performance.
Proprietary Drivers detailed, balanced audio
Definitive Technology designed the drivers in the Demand Series to deliver a perfectly balanced, precise, musical sound.
Clear, Precise Highs
The D17 couples a laterally offset 1" Aluminum Dome Tweeter with our 20/20 Wave Alignment Lens. We offset the tweeters by 5 degrees, minimizing wave cancellations off the front baffle to deliver a more precise center stereo image and ensure clear, detailed high-frequency performance.
Superior Detail & Natural Midrange
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 D17's 6.5" custom-woven carbon fiber woofers produce superior cone rigidity for deep, evenly extended bass notes while preventing distortion-causing cone deformation that can occur with less rigid materials.
Dual 8" Passive Bass Radiators for visceral bass response
Twin integrated 10” passive bass radiators in each speaker produce superior low-end extension for highly controlled, highly impactful bass.
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.
Linear Response Waveguide™ for natural, precise 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 D17 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 to fit any decor.
Each speaker is meticulously sanded and painted with five layers of premium gloss paint, then buffed to a near-mirror finish for an undeniably fashionable look in your home.
