Ultra Evolution Tower
The culmination of sonic obsession. Ultra Evolution Tower represents the culmination of SVS breakthroughs in driver design, component materials and cabinet architecture. The smallest of the flagship floorstanders, it outperforms everything in its class with rich, detailed sound, commanding bass and a broad yet precise soundstage.
Acoustically-centred time alignment, diamond-coated aluminium dome tweeters and a force-balanced woofer array embody an uncompromising approach to floorstanding speaker design, brought to life with painstaking anechoic and real-world voicing.
Design Highlights
- Acoustically-centred time-alignment cabinet: a curved front baffle aligns every driver on a vertical plane so sound reaches your ears at the same instant, for pinpoint imaging and an idealised point-source.
- Diamond-coated aluminium dome tweeter: vapour-deposited diamond carbon raises rigidity and pushes response beyond the limits of hearing for effortless, airy highs; an organic cell-lattice diffuser widens the sweet spot.
- Quad 5.25" glass-fibre woofers in a force-balanced array for deep, authoritative, evenly-spread bass with no mechanical coloration.
- Dual 4.5" glass-fibre midrange drivers for stunning dynamics and flawless tonal accuracy.
- Separate acoustically-tuned chambers, precision-cast aluminium baskets, chamfered baffle and neodymium magnetic grilles.
