SVS Ultra Centre Speaker

SVS Ultra Centre - The Foundation For High-End Home Theatres
The Ultra Centre anchors the front stage and immerses the listener in the cinema experience, effortlessly handling the most complex and dialogue-intensive scenes with stunning realism, room-filling presence and outstanding vocal reproduction and dialogue intelligibility.

Available in premium-grade piano gloss black and real black oak veneer finishes and handsomely styled with a swept back profile and striking edge treatments, the Ultra Centre will complement any high-end home theatre.

Dramatic Styling Yields Sonic Benefits
The Ultra Centre cabinet design yields numerous sonic benefits. The non-parallel cabinet panels reduce standing waves within the cabinet, effectively eliminating frequency response coloration. The wedge-shaped front baffle and flush-mounted drivers reduce edge diffraction and improved on-axis high frequency response. Even the grille design is FEA-optimised to maximise acoustic transparency.

SVS Drivers - Extreme Performance and Uncompromised Fidelity
The proprietary SVS drivers utilise the finest materials and design features to ensure the highest sound quality and performance. The Ultra Centre driver array features a 1" aluminium dome tweeter, a 4" midrange driver, and dual 6.5" woofers. The vertically aligned tweeter and midrange improves horizontal axis polar response, with reduced lobing and comb filtering for a smooth frequency response and excellent dialogue intelligibility at all listening positions.

The 1" aluminium dome tweeter utilises an FEA-optimised diffuser which delivers a very open 'airy' presentation and extremely unveiled highs.

The 4" midrange delivers amazing dialogue clarity and detail with powerful and room-filling presence and projection:

• A composite glass-fibre cone with excellent stiffness/mass ratio which improves sensitivity and maintains pistonic behaviour well beyond the pass-band of the driver.
• A vented voice coil former to minimise air compression artifacts at high drive levels.
• An aluminium shorting ring to reduce gap inductance, lower distortion, and improve high frequency response.
• A cast aluminium basket to ensure precise alignment of critical components and enhance heat-sinking capacity.

The 6.5" woofer delivers excellent lower midrange clarity, along with remarkably powerful and deep bass response:

• A composite glass-fibre cone with excellent stiffness/mass ratio which improves sensitivity and maintains pistonic behaviour well beyond the pass-band of the driver.
• A vented voice coil former to minimise air compression artifacts at high drive levels.
• An aluminium shorting ring to reduce gap inductance, lower distortion, and improve high frequency response.
• A cast aluminium basket to ensure precise alignment of critical components and enhance heat-sinking capacity.

SoundMatch Crossover Network - Intelligently Designed for Your Listening Room
The SoundMatch 3-way crossover features premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards to ensure pure signal transmission. Careful selection of the crossover frequency and slopes results in a smooth off-axis polar response, outstanding phase coherency and a stable sound stage.
