The SVS Ultra Evolution Tower is a flagship 3-way ported floorstanding speaker, launched in 2024, representing the pinnacle of SVS loudspeaker design. It features a revolutionary 1-inch Diamond-Coated Aluminum Dome Tweeter for pristine, distortion-free highs up to 40 kHz, paired with dual 4.5-inch glass fiber mid-range drivers. Four 5.25-inch glass fiber woofvers in a Force-Balanced Opposed Array deliver incredibly deep, controlled bass down to 30 Hz with virtually no cabinet vibration. Its distinctive Time-Aligned Cabinet Geometry with a curved front baffle ensures sound from all seven drivers reaches the listener simultaneously, creating a vast, precise soundstage with pinpoint imaging. Crafted from thick, braced MDF with dual rear ports, it ensures uncolored sound. With 800-watt peak power handling and dual bi-amp/bi-wire binding posts, the SVS Ultra Evolution Tower delivers reference-grade detail, dynamics, and unparalleled immersion, available in Piano Gloss Black, White, or Premium Black Oak.

Features

Acoustically Centered Time Alignment Cabinet Architecture
Curved front baffle aligns the sonic emanation point of all drivers on a vertical plane ensuring sound from each driver reaches your ears at the exact same instant.
Maximizes phase coherence for more convincing and immersive soundstage with pinpoint accuracy and imaging.
Midrange drivers and woofers positioned above and below the tweeter allow for seamless crossover blending to create an idealized “point-source” where sound flows from a single point in front of the speaker to optimize dispersion characteristics.

Diamond Coated Aluminum Dome Tweeter
Through a process called Vapor Deposition, a layer of diamond carbon is applied to the aluminum dome tweeters to vastly improve rigidity and acoustic properties.
This breakthrough in material science raises the frequency response well beyond the limits of human hearing resulting in effortless, airy, and unveiled highs with no measurable distortion.
The diamond coating also pushes low frequency extension of the tweeter deeper for more seamless blending with the midrange.
Organic cell lattice tweeter diffuser protects the dome and employs semi-random pattern derived from organic cell structures to improve off-axis response and maximize the listening “sweet spot.”

Quad 5.25” Glass-Fiber Woofers in Force Balanced Array
Dual opposing active woofers on the top and bottom of the cabinet render effortless low frequency response while addressing room modes. Deep, authoritative bass is evenly spread throughout the listening area.
Mechanical energy from each front-firing woofer is equaled inside the cabinet by the rear-firing woofer eliminating mechanical coloration for pure, accurate low frequencies at any playback level.

Dual 4.5" Glass Fiber Composite Midrange Drivers
Superb stiffness to mass ratio on dual driver array renders stunning dynamics with flawless tonal accuracy.

Unrelenting Attention to Detail
Separate, acoustically tuned internal chambers for the woofers and midrange drivers optimize separation and eliminate any potential for cabinet resonances, resulting in pristine sound across the frequency spectrum.
Uncompromisng 3-Way crossover with premium components seamlessly blends driver output. Subtle musical details are rendered with breathtaking clarity, while massive dynamics radiate with weight and control from the highest to lowest octaves.
Precision-cast aluminum-alloy baskets ensure precise alignment of critical components and maximize thermal dissipation.
Chamfered front baffle minimizes edge diffraction for optimal off-axis frequency response.

Cabinet:
- Acoustically Centered Time Alignment architecture.
-Acoustically-centered architecture orients the mid-range and woofer arrays in rotational-symmetry around the tweeter, ensuring that low, mid, and high-frequencies emanate from the same effective point in space, creating a coherent, integrated, faithful acoustic image.
- Time-aligned cabinet geometry introduces microsecond-level time delays between the drivers, ensuring that the effective acoustic-center of each driver is equidistant from the listener. The result is improved linearity and directionality throughout the crossover frequencies, and a more accurate soundstage.
- Quad 5.25” woofers in Force-Balanced Opposed Array energize any room with deep, accurate, evenly distributed bass, while contributing a net-zero vibration force to the cabinet and other components.
- Dual 4.5” midrange drivers share a dedicated acoustic-suspension enclosure, symmetrical around the tweeter.
- Chamfered front baffle and flush-mounted drivers reduce edge diffraction and improve on-axis and off-axis high-frequency response.
- Extra-thick 1” (25mm) driver baffles ensure a rigid, resonance-free mounting for all drivers.
- FEA-optimized ¾” (18mm) cabinet construction, extensive bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response, even at the highest drive levels.
