Ultra Centre Speaker

The reference 3-way SVS Ultra Centre channel speaker reproduces the most demanding movie and music content with depth, clarity and vigour, while serving as the main soundstage anchor and critical sonic bridge between the front left and right speakers in a surround sound home theatre. Amazingly detailed and revealing of the finest nuance and textures with excellent low frequency extension, the SVS Ultra Centre combines power and precision to outperform much larger and more expensive centre channel speakers.

Built without compromise, the SVS Ultra Centre speaker features a painstakingly tuned SoundMatch three-way crossover with dual 6.5-inch glass fibre composite woofers and a vertically aligned 1-inch aluminium dome tweeter and 4-inch midrange driver. From the acoustically enhanced cabinet geometry to the high-end components and build quality, the Ultra Centre is a star among home theatre speakers.

A centre channel speaker is often considered the most underrated speaker in a home theatre surround sound system because it handles the majority of dialogue, vocals, music and sound that’s coming from right in front of you in a movie, but rarely does a home theatre centre speaker get the same love as tower or bookshelf speakers. Many speaker manufacturers compromise with a two-way design or thin centre channel speaker with flimsy drivers as an afterthought, not SVS. The SVS Ultra Centre channel speaker flexes serious sonic muscle and is optimised for horizontal placement and elevating the most challenging movie and music content to reference quality.

Ultra Driver & Tweeter Design

For the all-important midrange where the majority of audio content lives, the SVS Ultra Centre speaker features a robust 4-inch composite Gras-fibre cone midrange driver with an excellent stiffness to mass ratio for high sensitivity and maintaining pistonic behaviour well beyond the pass-band of the driver. The midrange is housed in its own sub-enclosure and vertically aligned with the 1-inch aluminium dome tweeter, which features an FA-optimised diffuser to ensure broad dispersion for an incredibly wide and convincing soundstage and perfect on- and off-axis frequency response. This means the largest possible “Sweet Spot” so everyone can experience the same stunning clarity. Dual 6.5-inch woofers deliver effortless bass output and power handling capabilities rarely found in a centre channel home theatre speaker.

During movie, TV or music playback, all components within the Ultra Centre channel speaker act in perfect unison to provide crisp vocal clarity, unerring dialogue intelligibility and powerful dynamics, while anchoring the front stage with seamless transitional effects and a massive soundstage. Whether conveying the breathy dialogue of an intense conversation or the multi-layered, high-impact soundtrack of an action movie, the Ultra Surround speaker delivers a powerful and convincing audio experience.

Innovative SoundMatch Crossover Design

A three-way crossover design is imperative for a truly stand-out centre channel. The Ultra Centre speaker features a unique SVS SoundMatch three-way crossover with precisely tuned crossover frequencies and slopes that result in a smooth off-axis response, outstanding phase coherency and a stable, robust soundstage. Premium-grade capacitors, air-core inductors and other high end components ensure pristine signal transmission and utter neutrality.

Performance Driven Cabinet Design and Geometry

Every feature on the Ultra Centre channel speaker’s cabinet was designed with a sonic purpose in mind. Tapered edges on the cabinet’s front baffle, known as chamfers, minimise edge diffraction for clear and precise soundstaging. Internally, each cabinet employs separate sealed enclosures for both mid-bass drivers and tweeters to optimise performance and minimise interaction. Even the grille design is FA-optimised to maximise acoustic transparency.
