Laterally Offest Tweeter Assembly
5 x 9” Passive Bass Radiator
BDSS™ 5.25” Woofer and Linear Response
Featuring unique technologies such as our Balanced Double Surround System, linear response waveguide, and laterally offset tweeter assembly, the D9 Mid-Sized Bookshelf Loudpeakers deliver top-shelf, balanced audio for any application.
The D9 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, detailed high-frequency performance.
The D9’s 5.25” patented Balanced Double Surround System™ (BDSS) mid/bass driver provides greater excursion and output for superior midrange detail and smoother bass compared with other drivers of similar size.
The D9 produces superior low-end extension with an integrated 5” x 9” passive bass radiator. Plus, the addition of a larger spider to the radiator reduces rocking and delivers cleaner, tighter bass response.
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.
It isn’t always about the music. Designed for unwavering audio performance, the D9 flawlessly reproduces home cinema audio, too.
Extruded aluminum front baffles capture a clean, modern aesthetic with a bead-blasted finish to fit any decor.
