SVS Ultra Evolution Bookshelf Speakers

The SVS Ultra Evolution Bookshelf speaker represents SVS’s advancements in driver design, material selection, and cabinet architecture, combined with an unwavering passion for audio excellence. Delivering powerful and expansive sound that is revealing and detailed, the Ultra Evolution Bookshelf creates the illusion of a much larger speaker while maintaining refinement and precision.

Acoustically Aligned

One of the remarkable features of the Ultra Evolution Bookshelf speakers is their acoustically centered design. The front baffle is curved to ensure the tweeter and woofer are perfectly aligned, allowing the sound waves from each driver to reach the listener’s ears simultaneously. This maximizes phase coherence and creates a more convincing and engaging soundstage with exceptional accuracy and imaging.

Aluminum Dome Tweeter and Fiberglass Woofer

SVS has introduced a revolutionary diamond-coated aluminum dome tweeter in the Ultra Evolution series. Using advanced vapor deposition technology, a layer of diamond carbon is grown on the surface of the aluminum dome, enhancing its stiffness and acoustic properties. This breakthrough pushes the frequency response beyond the limits of human hearing, resulting in airy and unveiled highs with virtually no measurable distortion. The tweeter’s low-frequency extension is also improved, allowing for a seamless blend with the midrange.

The Ultra Evolution Bookshelf speakers employ a 6.5-inch fiberglass composite woofer, meticulously engineered to deliver breathtaking dynamics and uncompromising tonal accuracy. The precision-machined aluminum alloy basket ensures precise alignment of critical components and maximizes heat dissipation, resulting in consistent performance even under demanding conditions.

Meticulous Attention to Detail

Every aspect of the Ultra Evolution Bookshelf speaker’s design has been meticulously optimized for uncompromising audio performance:

• The cabinet is acoustically tuned to eliminate any chance of resonance, ensuring flawless sound reproduction across the entire frequency spectrum.
• The crossover network uses premium-grade components to seamlessly blend the tweeter and woofer signals, rendering the most subtle musical details with stunning clarity.
• The precision-machined aluminum chassis maintain precise alignment of critical components while maximizing heat dissipation.
