The Ultra Bookshelf speakers represent an uncompromising approach to loudspeaker design. From the drivers and crossover to the build materials and cabinet design, every element is painstakingly engineered and tested to achieve reference sound quality.
Ultra Driver & Tweeter Design
A commanding presence in any home audio system, the 6.5-inch mid-bass drivers feature composite glass-fiber cones that yield excellent stiffness to mass ratio for enhanced sensitivity and voicing that’s transparent and completely faithful to the source material. These capable drivers render an accurate tonal balance with effortless authority and dynamics. Whether conveying the varied nuances of musical instruments and dialogue or the sonic impact of sound effects and movie scores, the Ultra drivers deliver pinpoint accuracy with precise imaging and a massive soundstage.
Elevating high frequency performance, the Ultra Bookshelf speaker’s aluminum dome tweeter is pristinely neutral and revealing. Light, efficient, rigid and impervious to distortion, even at high sound pressure levels, the tweeter’s airy’ presentation of vocals and unveiled highs compare with the best tower and bookshelf speakers in the world. The FEA-optimized diffuser ensures broad dispersion for an incredibly wide and convincing soundstage and perfect on- and off-axis frequency response so everyone in your room experiences the same stunning clarity.
Innovative SoundMatch Crossover Design
No expense was spared with the innovative SVS SoundMatch two-way crossover. The unique topology creates a broad, yet focused and precise soundstage, with accurate frequency response and imaging at all listening positions. The precise tuning of the SoundMatch Crossover also ensures balanced output from sparkling highs to the crystal clear and commanding midrange, down to visceral and authoritative bass.
Performance Driven Cabinet Design and Geometry
Every feature on the Ultra Bookshelf speaker cabinet is designed with a sonic purpose in mind. Tapered edges on the cabinet’s front baffle, known as chamfers, minimize edge diffraction for clear and precise soundstaging. Internally, each cabinet employs separate sub-enclosures of the mid-bass driver and tweeter to optimize performance and minimize interaction between drive units.
Meticulous, Innovative Design Process
All SVS speakers, regardless of price or form factor, are crafted in the same painstaking fashion. Call it a marriage of exacting science and a passionate expression of technique and love of great sound.
Before a model is ever constructed, drivers and cabinets are theoretically designed by our acoustic engineers using sophisticated computer-aided design (CAD) processes . Then prototypes are carefully measured and optimized in an anechoic environment to achieve pitch-perfect frequency response. After the ideal theoretical frequency response is attained, exhaustive listening and measurement is done in listening rooms calibrated to closely resemble typical home-like room environments.
The result is a speaker that measures well with near-perfect real world frequency response, but also optimized to sound amazing on a human level through listening tests with real music and cinematic content, in a real world listening environment like your home.
