Mighty Small

D7 bookshelf speakers hit the sweet spot of smooth high-frequency reproduction and three-dimensional imaging with an elegant, minimalist footprint that fits virtually anywhere.

Small But Mighty

Improved low-end extension within a small-footprint cabinet.

Focus on the Details

Laterally offset aluminum dome tweeters.

Natural Mids and Bass

Linear response waveguide™ and BDSS™ woofer.

Expect Big Things

Featuring unique technologies such as our Balanced Double Surround System™, linear response waveguide, and laterally offset tweeter assembly, D7 Compact Bookshelf Loudspeakers pack a ton of punch in a compact package.

Aluminum Dome Tweeter for Clear, Precise Highs

The D7 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 clear, detailed high-frequency performance then you’d ever expect from a compact speaker.

Exclusive BDSS™ Midrange/Woofer

The D7’s dual 4.5” patented Balanced Double Surround System™ (BDSS) woofers provide greater excursion and output for superior midrange detail and punchier bass compared with other drivers of similar size.

Audiophile-Quality Crossovers for Precise Detail

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.

For Music and Movies

True audiophiles are obsessive about all sound, not just their music. The D7s can not only bring extraordinary life to your TV sound as the front face of a small home cinema system, they can also double as rear surrounds in a big home theater system to deliver extraordinary immersive 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 that seamlessly blends into 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 ho
