Reference flagship bookshelf speaker is a technology tour-de-force that stands toe-to-toe with the finest loudspeakers in the world delivering reference sound for both two-channel audiophiles and home theater fans. The Culmination of Sonic Obsession. SVS Ultra Evolution Bookshelf speaker represents the culmination of SVS breakthroughs in driver design, component materials, and cabinet architecture, married with a relentless passion for audio excellence. The science of sonic perfection in harmony with a love of convincing and immersive sound. With a big, expansive sound that’s revealing and detailed, Ultra Evolution Bookshelf gives the impression of a much larger speaker without sacrificing refinement or accuracy. Never has this fusion of design elements existed in a single speaker. Time aligned cabinet geometry, diamond coated aluminum dome tweeters, organic cellular lattice diffuser, and other advancements embody an uncompromising approach to speaker design. These innovations are brought to life with painstaking anechoic and real-world measurement and voicing. This final bit of artistry places Ultra Evolution Bookshelf among the highest fidelity speakers ever created. The company's mission has always been to ignite a passion for transcendent music and home theater experiences by rendering the truest sonic playback. The joy of pristine clarity, absolute transparency, stunning dynamics, and effortless bass for more people than ever. SVS Ultra Evolution Bookshelf deeply connects you to the emotion of sound. Inspired Design, Reference Performance. Time Aligned Cabinet Geometry Curved front baffle aligns the sonic emanation point of the tweeter and woofer on a vertical plane ensuring sound from each driver reaches your ears at the exact same instant. Maximizes phase coherence for more convincing and immersive soundstage with pinpoint accuracy and imaging. Diamond Coated Aluminum Dome Tweeter Through a process called Vapor Deposition, a layer of diamond carbon is applied to the aluminum dome tweeters to vastly improve rigidity and acoustic properties. This breakthrough in material science raises the frequency response well beyond the limits of human hearing resulting in effortless, airy, and unveiled highs with no measurable distortion. The diamond coating also pushes low frequency extension of the tweeter deeper for more seamless blending with the midrange. Organic cell lattice tweeter diffuser protects the dome and employs semi-random pattern derived from organic cell structures to improve off-axis response and maximize the listening “sweet spot.” 6.5" Glass Fiber Composite Mid-Woofer Superb stiffness to mass ratio conveys stunning dynamics with flawless tonal accuracy, and deep, accurate bass. Unrelenting Attention to Detail Acoustically tuned enclosure optimizes low frequency tuning and eliminates any potential for cabinet resonances, resulting in pristine sound across the frequency spectrum. Uncompromising 2-Way crossover with premium components seamlessly blends driver output. Subtle musical details are rendered with breathtaking clarity, while massive dynamics radiate with weight and control from the highest to lowest octaves. Precision-cast aluminum-alloy baskets ensure precise alignment of critical components and maximize thermal dissipation. Chamfered front baffle minimizes edge diffraction for optimal off-axis frequency response.
