From Manufacturer
Enjoy balanced stereo sound from this pair of piano black Definitive Technology Demand Series D7 2-Way Bookshelf Speakers. They feature a 2-way design with a 1" aluminum dome tweeter and a 4.5" polypropylene BDSS woofer, plus a bass port for enhanced low end response. The speakers accept 20 to 125W from your amplifier and have a 67 Hz to 22 kHz frequency response. The included magnetic grilles are designed to be acoustically inert to avoid coloration of the sound.
1" Aluminum Dome Tweeters
Coupled with the 20/20 Wave Alignment Lens, the annealed aluminum dome tweeter delivers smooth high frequency response and enhanced dispersion for a rich, balanced listening experience. Offsetting the tweeter by 5° is designed to provide a more precise center stereo image by minimizing undesirable symmetric diffraction off the corners of the front baffle.
Linear Response Waveguide
The Linear Response Waveguide is engineered to extend both on- and off-axis frequency response while improving dispersion for a more natural midrange timbre and more precise imaging.
BDSS Mid-Woofer
The Balanced Double Surround System mid-woofer helps provide enhanced excursion and output for augmented midrange detail and bass.
Bass Port
The bass port in each speaker is designed to provide enhanced low-end extension by transitioning air flow from the speaker into your listening area for deep, extended bass impact with reduced turbulence and distortion.
Acoustically Transparent Magnetic Grille
The included acoustically transparent magnetic black speaker grilles are designed to provide natural, uncolored sound when placed on the speaker, and to remove easily when you want to see your speakers uncovered.
Extruded Aluminum Front Baffle
The bead-blasted finish of the front baffle is fashioned to blend into nearly any décor.
Painted Piano Black Cabinet
The cabinet is designed to blend into your lifestyle, and is sanded and painted with five layers of piano black paint, then buffed for a Level 6 near-mirror finish.
