Definitive Technology Demand Series D11 High-Performance Bookshelf Speakers – Pair
Integrated Bass Radiator
for superior low-end extension
The D11 produces superior low-end extension with an integrated 6” x 10” passive bass radiator. Plus, the addition of a larger spider to the radiator reduces rocking and delivers cleaner, tighter bass response.

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™
all natural, totally precise
Our patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.
Meticulous Masterful Sound
Flawless Home Theater Audio
True audiophiles are obsessive about all sound, not just their music. Designed with meticulous attention to detail, the D11 also flawlessly reproduces 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.
