Every design element of the SVS Ultra Surround speakers was scrutinized to achieve cost-no-object audio performance and build quality, creating a groundbreaking home theater surround sound loudspeaker. Countless design innovations and world-class build materials result in reference sound quality and stunning dynamics normally reserved to for the world’s most expensive speakers.

Whether playing the aggressive, multi-layered soundtrack of an action movie or the understated effect of rain falling all around the listener, the Ultra Surround speaker delivers a powerful and convincing audio experience. From the drivers to the crossover and cabinet, each component is painstakingly engineered and tested to achieve breathtaking realism.

Room-filling low frequency and midrange playback is handled by dual 5.5-inch mid-bass drivers that feature glass-fiber cones with excellent stiffness to mass ratio for enhanced sensitivity and voicing that’s transparent and completely faithful to the source material. Whether conveying the nuance of subtle surround effects like a car driving by or a door closing, or the head-spinning sonic impact of an explosion happening behind you, the Ultra Surround drivers deliver pinpoint accuracy with precise imaging and a massive soundstage.

Elevating high frequency performance, the Ultra Surround 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, unveiled highs compare with the best home theater surround sound speakers in the world. The FEA-optimized tweeter diffuser ensures broad dispersion for a wide and convincing soundstage and perfect on- and off-axis frequency response. This means the largest possible “Sweet Spot” for surround effects so everyone can be equally immersed with what’s happening onscreen.

No expense was spared with the innovative SVS SoundMatch two-way crossover. The unique topology reveals a broad, yet focused soundstage, with accurate frequency response and imaging at all listening positions. You clearly sense the directionality of sound coming from different places all around you. The crossover also enables SVS’s innovative Duet Mode, so you can go from 5.1 to 7.1 or 7.1 to 9.1 without adding additional surround sound speakers. The precise tuning of the SoundMatch Crossover also ensures balanced output throughout the frequency spectrum.

The Ultra Surround speaker also comes standard with a wall-mounting bracket or it can easily be placed on a speaker stand for maximum placement flexibility.

Every feature on the Ultra Surround speaker’s cabinet was 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 sealed enclosures for both mid-bass drivers and tweeters to optimize performance and minimize interaction. Even the grille design is FEA-optimized to maximize acoustic transparency.

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 using the most sophisticated computer-aided design (CAD) processes in the world. Then prototypes are carefully measured and optimized in an anechoic environment for 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 yours.
