Definitive Technology D11 Large Bookshelf Speakers

Full-range, room-filling sound and precise imaging. These are the true audiophile’s bookshelf loudspeaker of choice. Featuring unique technologies such as our Balanced Double Surround System™, linear response waveguide, and laterally offset tweeter assembly, the D11 Large Bookshelf Speakers deliver remarkably smooth, detailed top-shelf audio for true audiophiles.

Definitive Technology D11 Large Bookshelf Speakers

The D11 couples a laterally offset 1-inch Aluminium Dome Tweeter with our 20/20 Wave Alignment Lens™. We offset the tweeters by 5°, minimising wave cancellations off the front baffle to deliver a more precise centre stereo image and ensure clear, detailed high-frequency performance. The D11’s 6.5-inch patented Balanced Double Surround System™ (BDSS) woofer provides greater excursion and output for superior midrange detail and punchier bass compared with other drivers of similar size. It produces superior low-end extension with an integrated 6 x 10 inch passive bass radiator. Plus, the addition of a larger spider to the radiator reduces rocking and delivers cleaner, tighter bass response.

Demand Series crossovers are built with the latest premium audiophile-quality parts, including polypropylene metal-film capacitors and air-core inductors. These high-end components meticulously manage frequencies for clean and crystalline treble, refined and articulate midrange, and linear, low-distortion bass. This ensures that every detail comes through within a clear, balanced presentation that never sacrifices power. Definitive Technology's patented Linear Response Waveguide™ extends both on-axis and off-axis frequency dispersion for more natural midrange timbre and precise imaging.

True audiophiles are obsessive about all sound, not just their music. Designed with meticulous attention to detail, the D11 also flawlessly reproduces home theatre audio. Extruded aluminium front baffles capture a clean, modern aesthetic with a bead-blasted finish for a timeless look and feel to fit any décor. Each speaker is meticulously sanded and painted with five layers of premium gloss paint, then buffed to a near-mirror finish.

Tweeter

A tweeter is a type of loudspeaker driver designed to reproduce high-frequency sounds in an audio system. It is responsible for producing the treble or high-pitched frequencies in music and audio recordings. Tweeters are essential components in multi-driver speaker systems, such as two-way, three-way, and more complex speaker designs, where different drivers are dedicated to reproducing specific frequency ranges.

Key characteristics and features of tweeters include:

Frequency Range: Tweeters are designed to handle high-frequency sounds, typically ranging from around 2,000 Hertz (Hz) to 20,000 Hz (20 kHz) and above. This range covers the uppermost portion of the audible spectrum.
Diaphragm Material: Tweeter diaphragms are often made from lightweight and rigid materials that can respond quickly to high-frequency vibrations. Common diaphragm materials include fabric, silk, aluminum, titanium, beryllium, and diamond.
Driver Types: Tweeters can be found in various driver designs, including dome tweeters, ribbon tweeters, cone tweeters, and horn-loaded tweeters. Each type has its own characteristics and advantages.
Dispersion: Tweeters are designed to provide wide dispersion of high-frequency sound to ensure that the treble frequencies are evenly distributed throughout the listening area.
Crossover: In multi-driver speaker systems, a crossover network is used to direct specific frequency ranges to different drivers. The crossover ensures that the tweeter only receives and reproduces high-frequency signals.
Power Handling: Tweeters have different power handling capabilities, which indicate the maximum amount of power they can handle without distortion or damage.
Sensitivity: Tweeter sensitivity refers to how efficiently the tweeter converts electrical signals into sound. Higher sensitivity allows for more output with less input power.
Waveguide or Horn: Some tweeters are equipped with waveguides or horns to control and improve the dispersion of high-frequency sound.

Tweeters work in conjunction with other drivers in a speaker system, such as midrange drivers and woofers, to create a full and balanced sound. The combined efforts of these drivers result in accurate audio reproduction across the entire frequency spectrum.

When selecting speakers or audio equipment, it's important to consider the quality and design of the tweeters to ensure that they contribute to clear and detailed treble reproduction. A well-designed tweeter can enhance the overall audio experience by reproducing intricate details, harmonics, and spatial cues present in music and audio recordings.
