8” Aluminum Dome Tweeter for Clear, Precise Highs

The Demand 9 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.

Exclusive BDSS™ Midrange/Woofer

The Demand 9’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.

Integrated Bass Radiator for Superior low-end Extension

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.

Audiophile-Quality Crossovers for Balance and Power

The Demand 9 is 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 Imaging

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

Flawless Home Theater Audio

It isn’t always about the music. Designed for unwavering audio performance, the Demand 9 flawlessly reproduces home cinema audio, too.

Artistry to the Eye and Ear

Extruded aluminum front baffles capture a clean, modern aesthetic with a bead-blasted finish 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 for an undeniably fashionable look in your home.
