Definitive Technology Demand Series Speakers at CEDIA 2017

At CEDIA 2017 Definitive Technology introduced a new line of standmount speakers, the Demand Series. The three models, called Demand D11 ($999/pair), Demand D9 ($749/pair), and Demand D7 ($499/pair), which are striking-looking speakers that are designed to offer high perfomance in a compact package. These speakers are an update to the Studio Monitor range.

All three models are sold as matching pairs that feature offset 1″ waveguide-mounted aluminum-dome tweeters that have a “20/20 Wave Alignment Lense.” The goal of the design is to improve stereo imaging by eliminating symmetrical baffle diffraction.

One important feature of these new speaker models is the marketing specs now include +/-3 dB anechoic response measurements. As a result, you can make apples-to-apples comparisons with other accurately-specified products. Plus, they sport the sharp, modern, minimalist look that defines the latest Definitive Technology products.

The Demand D7 is the smallest model. It is a ported design that sports a 4.5″ polypropylene BDSS (Balanced Double Surround System) woofer and offers 85 dB/W/m sensitivity and a response of 67 Hz to 21 kHz (+/-3 dB) with a “total frequency response” of 57 Hz to 24 kHz. Cabinet dimensions are 9.75″ (H) x 5.5″ (W) x 8.75″ (D). Power handling is rated as up to 125 watts.

The step-up Demand D9 is the middle model and uses a 5.25″ polypropylene woofer that is augmented by a 5″ x 9″ racetrack oval-shaped passive radiator.  This combination provides 88 dB/W/m sensitivity and a frequency response of 64 Hz to 22 kHz (+/-3 dB) with a “total frequency response” of 44 Hz to 24 kHz. Cabinet dimensions are 11.71″ (H) x 6.5″ (W) x 11.97″ (D). This model can handle up to 150 watts of power.

At the top of the Demand Series heap you’ll find the D11. This model has a 6.5″ woofer that works along with a 6″ X 10″ racetrack oval-shaped passive radiator to achieve a sensitivity of 90 dB/W/m and an anechoic response of 61 Hz to 22 kHz (+/-3 dB) and a “total frequency response” of 48 Hz to 24 kHz. Cabinet dimensions are 13″ (H) x 7.25″ (W) x 12.5″ (D). The D11 can handle up to 200 watts of power.

The combination of striking good looks and the performance I heard (despite difficult show floor listening conditions) were enough to convince me the Demand Series from Definitive Technology deserves a Best of CEDIA 2017 award.

In addition to the three new Demand speaker models, Definitive Technology also unveiled a new dedicated stand for the series, the Demand ST1 ($399/pair). All of these new products will be available in the second half of September 2017 at retailers including Magnolia at Best Buy.
