3-Way Configuration and
Laterally Offset Tweeters for a Precise
Balanced Double Surround System
and 6.5” Mid/Bass Woofers
The D15 tower speaker features an exclusive 3-way driver configuration with a 1” annealed aluminum dome tweeter, a 5.25” BDSS™ midrange woofer, and dual 5.25” carbon fiber bass drivers, complemented by dual 8” side-firing passive radiators, for a full-range, room-filling sonic performance.
Definitive Technology designed the drivers in the Demand Series to deliver a perfectly balanced, precise, musical sound.
The D15 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.
Twin integrated 8” passive bass radiators in each speaker produce superior low-end extension for highly controlled, highly impactful bass.
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.
Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.
True audiophiles are obsessive about all sound, not just their music. The meticulous attention to detail that enables the D15 Tower Speaker to beautifully reproduce music also enables it to flawlessly reproduce home theater audio.
Extruded aluminum front baffles capture a clean, modern aesthetic with a bead-blasted finish to fit any decor.
