SVS Ultra Evolution Tower 3-Way Floorstanding Speaker (Each)

The SVS Ultra Evolution Tower is a three-way floorstanding loudspeaker built around an acoustically centered driver architecture and time-aligned cabinet geometry. Its sophisticated array combines a 1" diamond-coated tweeter, dual 4.5" glass-fiber composite midrange drivers and four 5.25" woofers arranged in a force-balanced opposed configuration.

The acoustically centered architecture positions the midrange and woofer arrays with rotational symmetry around the tweeter so low, mid and high frequencies emanate from the same effective point in space. Time-aligned cabinet geometry introduces microsecond-level delays between the drivers so their effective acoustic centres are equidistant from the listener, improving linearity and directionality through the crossover regions while producing a coherent, accurate soundstage.

Features:

• Three-Way Tower Design - Sophisticated driver array combines dedicated high-frequency, midrange and bass drivers in a floorstanding enclosure.
• 1" Diamond-Coated Tweeter - Vapor deposition applies a hyper-rigid diamond carbon coating to an aircraft-grade aluminum dome for extended high-frequency response, linearity and fast transient performance.
• Organic Cell Lattice Diffuser - FEA-optimized tweeter diffuser is designed for open, detailed high-frequency reproduction and pristine clarity.
• Dual 4.5" Midrange Drivers - Glass-fiber composite cones provide a high stiffness-to-mass ratio, while precision-cast aluminum-alloy baskets maintain driver alignment and aid thermal dissipation.
• Quad 5.25" Woofers - Four long-stroke glass-fiber composite woofers provide high-output low-frequency reproduction.
• Force-Balanced Opposed Woofer Array - Opposing woofer configuration delivers deep, evenly distributed bass while producing a net-zero vibration force on the cabinet and other components.
• Acoustically Centered Architecture - Midrange and woofer arrays are arranged with rotational symmetry around the tweeter to create a coherent, integrated acoustic image.
• Time-Aligned Cabinet Geometry - Carefully designed cabinet geometry introduces microsecond-level driver delays so the effective acoustic centres reach the listener in alignment.
• Dedicated Midrange Enclosure - Dual midrange drivers share an acoustic-suspension chamber positioned symmetrically around the tweeter.
• Premium 3-Way Crossover - Uses premium-grade capacitors, inductors and resistors with a heavy-trace printed circuit board.
• Dual Rear-Firing Ports - Two 2.5" wide-flared rear ports support low-frequency output.
• Rigid, Braced Cabinet - FEA-optimized 3/4" cabinet construction, extensive bracing and acoustic insulation help suppress structural and acoustic resonances.
• 1" Driver Baffles - Extra-thick driver baffles provide rigid, resonance-resistant mounting for the drivers.
• Reduced Edge Diffraction - Chamfered front baffle and flush-mounted drivers improve on-axis and off-axis high-frequency response.
• Dual 5-Way Binding Posts - Gold-plated connections provide flexible speaker cable termination.
• Magnetic Grille - Cloth grille attaches using a magnetic retention system.
• Adjustable Feet - Includes adjustable elastomer screw-in feet and adjustable spiked metal feet.
