A full sonic soundstage

An offset aluminum dome tweeter delivers clean high, while a BDSS™ (Balanced Double Surround System) midrange/woofer accurately reproduces mids and low frequencies.

Our friends at Definitive Technology have leveraged the most innovative audio advancements to create a speaker that delivers a smooth, articulate and powerful lightweight bookshelf speakers. To create a precise and clean audio production along the high frequency range, the D7 uses an offset aluminum dome tweeter coupled with a 20/20 Wave Alignment Lens. The soundstage is rounded out by a patented Balanced Double Surround System (BDSS) midrange/woofer that delivers detailed mids and powerful and articulate bottom end.

Modern and elegant design

Sleek and stylish, the D7 can fit on a bookshelf but looks so handsome you will want to prominently display it in your living space. Each D7 speaker is meticulously handcrafted with artisan-quality details -- each cabinet is meticulously sanded, and painted with five layers of premium black gloss paint that is  buffed to a near-mirror finish.

Quality Components

The speakers of the D7 are housed in a resonance-deadening MDF cabinet. This wonder of audio engineering eliminates speaker vibration and unwanted distortion, while improving overall sound quality. The magnetic black grille is designed to helps the speaker blend into your room’s interior decorating and allows your speakers to deliver natural, uncolored sound.

Absolutely wonderful sounding speakers! Clear, detailed, wide soundstage w zero brightness or sibilance. They also have a surprising amount of bass for such a small speaker. These are keepers!

Incredible detail and presence
Wow. I have the D11's, and they are excellent speakers. I am using these speakers in my kitchen with a Marantz MRC-12 network receiver and an external amp. The sound coming from these small but dense speakers is remarkable. Detailed, clean, not at all fatiguing ever. And the bass extension is truly amazing-clean, deep, and full, not lean or anemic at all. If you close your eyes you would swear the sound was coming from much larger speakers. 2 thumbs way up, and they are works of art as well. No holds barred recommended.

They have a very fine sound for the size they have. The design is very modern and has a really great quality. Very good buy. It seems to look bigger.
