About the Definitive Technology Demand Series D7

Built for stereo precision

I've long been a fan of Def Tech's range of high-quality bookshelf speakers. They combine thoughtful cabinet design with high-tech driver components for huge, natural sound. The D7 is the smallest speaker in company's Demand Series lineup, and it offers terrific stereo performance without taking up too much space in your room.

Built for stereo precision

I've long been a fan of Def Tech's range of high-quality bookshelf speakers. They combine thoughtful cabinet design with high-tech driver components for huge, natural sound. The D7 is the smallest speaker in company's Demand Series lineup, and it offers terrific stereo performance without taking up too much space in your room.

A tweeter designed with music in mind

One of the coolest parts of the D7 is its all-new tweeter design. Each speaker uses a 1" annealed (heated and then slowly cooled) aluminum tweeter for super-smooth, natural highs. Each tweeter is offset from its corresponding woofer by 5°, which helps it deliver a precise center image — a crucial component of the stereo listening experience. 

Def Tech employs its Linear Response Waveguide™ on each tweeter, which helps create a wide "sweet spot" and a lifelike soundstage. Each speaker is labeled as "right" or "left" to optimize stereo playback (and for visual reference, the left speaker's tweeter is offset to the left of the woofer, and vice versa for the right speaker).

Definitive Technology D7 bookshelf speaker

Each D7 speaker uses an offset tweeter for precise stereo imaging and a wide sweet spot.

Solid midrange and bass

Each D7 sports a 4" Balanced Double Surround System (BDSS) polypropylene woofer. These custom-designed drivers deliver articulate midrange and punchy bass. A rear-firing port on each enclosure extends low-frequency response while minimizing turbulence and distortion.

Add a sub for deeper thump

Love deep bass with your music? Given the relatively small size of the D7 woofers, I recommend pairing these speakers with a Definitive Technology powered subwoofer for deeper bass reproduction.

Get the most out of your stand-mount speakers

I'm a proponent of using high-quality speaker stands with bookshelf speakers. They help improve the sound by giving your speakers a stable, vibration-free platform. When shopping for stands, remember that the ideal height will place the tweeters roughly level with your ears, for maximum clarity.

Speaker stands also give you more placement flexibility, since you won't be limited to a space on your shelf or table. Keeping your speakers away from the wall or the corner of a bookshelf can also prevent excessively boomy bass. Many stands even offer built-in cable management for a neat, clean install.

The Sanus SF22 steel stands are an excellent choice to use with the D7s, but feel free to contact one of our Advisors for a specific recommendation for your setup.

Product Research


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 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 magnetic grille. The included acoustically transparent magnetic 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).

Mounting Options: The Demand Series D7 bookshelf speakers can simply be placed on a speaker stand, desk, table or shelf. Definitive offers a speaker stand (735DST1, sold separately) specifically designed for the Demand Series bookshelf speakers. Integrated rubber pads on the bottom of the speakers provide stability and protection. Each speaker is also fitted with a back panel 3/8" threaded insert to wall mount the speakers using optional brackets (sold separately).

Note: Currently Crutchfield does not offer a wall bracket with 3/8" mounting hardware. However, you can use the Pinpoint side-clamping brackets (sold separately - see Accessories tab) to wall mount the speakers

Placement: The D7 bookshelf loudspeakers and your main listening position should be setup in an equilateral triangle that measures 7-10' from each speaker and the listening position. The speakers should be placed approximately 2-6' from side walls and 2-4' from back walls. The speakers should be mounted as close to ear level as possible with the listening position. Toeing the speakers in slightly, toward your listening area will provide stronger stereo imaging.

Demand Series: The Definitive Technology Demand Series 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 speakers deliver an unrivaled sweet spot, smoother high-frequency reproduction, and three-dimensional imaging for a technically-advanced, premium listening experience. Definitive Technology's Demand Series consists of two floorstanding loudspeakers (D15/D17), three bookshelf loudspeakers (D7/D9/D11), and a center-channel loudspeaker (D5C).

Optional Powered Subwoofer: Add one of Definitive Technology's powered subwoofers (sold separately - see Accessories Tab) for bigger, deeper, and more dynamic bass response.

Customer Q&A

1 question already asked

Looking at the Def Tech Demand bs speakers. Two questions: 1) if I use these in a 5.1 system, which center pairs best and 2) if I plan to use a sub with them does the D7 w/o a bass radiator make the most sense ? Medium size room (2500 ft3) with a high ceiling. 75% movies, 25% music.

I'm using the definitive technology ca9060 center channel. The bass on the D7 is pretty good but when paired with a sub is when they really shine. Im using a super cube 2000 for my subwoofer and the definitive technology bp9040 towers. The towers and the center each have a 8" sub inside them so all together the bass is amazing. If your using these as your left and right channel I would go with the d9s or the d11s if I wasn't using these as my rear speakers I would have done the d9s.
