Demand Series Bookshelf Loudspeakers: The Definitive Technology Demand Series D7 high-performance bookshelf loudspeakers deliver full-range, room-filling sound and precise imaging in a modern, elegant styling. Featuring technology advancements to both Definitive's aluminum dome tweeter and midrange/woofer sections, these speaker deliver an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for a technically-advanced, premium bookshelf listening experience.
1" Aluminum Dome Tweeter: The 1" annealed aluminum tweeter is precision engineered to articulate nuance and detail in the high-frequency bands for a crystal-clear listening experience. Offsetting the tweeter by 5° delivers a more precise center stereo image by eliminating undesirable symmetric diffraction off the corners of the front baffle.
- 20/20 Wave Alignment Lens: Coupled with Definitive's new 20/20 Wave Alignment Lens, the 1" annealed aluminum dome tweeter delivers smoother high frequency response and improved dispersion for a rich and balanced listening experience.
- Linear Response Waveguide: A patented Linear Response Waveguide extends both on and off axis frequency response, while improving dispersion for more natural mid-range timbre and more precise imaging.
Note: Because the tweeters are offset, the bookshelf speakers are labeled for left (L) and right (R) on back of the cabinet.
4" BDSS (Balanced Double Surround System) Midrange/Woofer: A patented 4" Balanced Double Surround System (BDSS) polypropylene midrange/woofer provides greater excursion and output that results in superior midrange detail and punchier bass compared to drivers of similar size. The speaker's balanced double surrounds support the cone at two points to provide better mechanical stability for longer, more linear excursion, and improved damping to suppress cone resonance.
Bass Port: A rear-firing bass port provides superior low-end extension by smoothly transitioning air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion.
Hand Crafted Cabinet: The speaker cabinets are constructed from MDF with an extruded natural bead-blasted aluminum front baffle. The cabinets are hand-crafted, meticulously sanded, painted with five layers of premium black gloss paint, and then buffed for a near-mirror finish (Level 6) for an uncompromising look in your home.
Acoustically Transparent Magnetic Grille: Each bookshelf loudspeaker also comes with an acoustically transparent black magnetic grille. The included acoustically transparent magnetic black speaker grilles provide natural, uncolored sound when placed on the speaker, and remove easily when you want to enjoy looking at them fully uncovered.
Gold-Plated Binding Posts: Each bookshelf speaker is outfitted with a set of gold-plated, 5-way binding post terminals to connect bare speaker wire (up to 10AWB), pin-connectors, spade-lugs, and banana plugs (single or dual) Note: In order to use banana plugs, you must completely unscrew the binding-post terminals and remove the rubber caps. Once you have removed the rubber caps, you can fully screw down the binding-post terminals and connect your banana plugs (sold separately).
