About Definitive Technology Demand 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 Definitive Technology Demand 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 Definitive Technology Demand 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.
