The SVS Ultra Evolution Bookshelf is a precision-engineered speaker designed to deliver high-fidelity sound in a compact form. Its one-inch diamond-coated aluminium tweeter uses an advanced vapour deposition process to enhance rigidity without adding weight, resulting in crystal-clear highs free from distortion. Paired with an organic cell lattice diffuser, it ensures wide dispersion, so every seat in the room experiences pristine detail. Whether it's the delicate shimmer of cymbals or the subtle texture of a vocal performance, this speaker delivers an open and transparent listening experience.
A 6.5-inch glass fibre composite woofer provides deep, controlled bass and rich midrange clarity, maintaining accuracy even at high volumes. The time-aligned cabinet design ensures that sound from both drivers reaches your ears simultaneously, creating a precise and immersive soundstage. Built with a heavily braced, resonance-free enclosure and a premium crossover, the Ultra Evolution Bookshelf blends every frequency, making it perfect for both music lovers and home cinema enthusiasts.
