Very happy

Louis from Naples, fl on 1/2/2018

Crutchfield Customer Review (What's this?)

I got the definitive technology d7 to use as my surround speakers in my 5.2.2 set up and I'm extremely happy with the performance and build quality. Sound is great especially for the price. I don't no if I would recommend these as main speakers maybe go for the d9 or d11s for that but for what I use them for I couldn't be happier. Five stars for sure.

Pros: Build quality, price, sound.

Cons: None

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).

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.

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. [ Louis  Jan 22, 2018 ]
