Product Description

The SVS Ultra Evolution Bookshelf combines a 6.5-inch glass-fibre woofer with a diamond-coated aluminium dome tweeter. Its time-aligned cabinet and carefully designed crossover support detailed stereo reproduction, while the compact enclosure also suits front or surround home cinema duties.

Driver Specs:

1” Diamond Coated Tweeter

• FEA-optimized Organic Cell Lattice Diffuser for airy, unveiled highs and pristine clarity.
• Cutting-edge vapor-deposition grows a hyper-rigid diamond-like coating on an aircraft-grade aluminum dome, pushing high-frequency extension further beyond human hearing, and delivering best-in-class fidelity, linearity, and transient response.
• Silver tinsel leads for optimal signal transfer and power handling.

6.5” Woofer:

• Long stroke motor and suspension for high output.
• Composite glass-fiber cone with excellent stiffness/mass ratio for high sensitivity and pistonic behavior beyond passband.
• Precision-cast aluminum alloy baskets ensure precise alignment of critical components and maximize thermal dissipation.
• Vented aluminum voice coil former to maximize thermal control while minimizing air compression artifacts at high drive levels.

Crossover & Cabinet Specs:

Crossover:

• 2-way crossover with premium-grade capacitors, inductors, resistors, and heavy-trace printed circuit board
• Tweeter-to-Woofer crossover: 1.8 kHz

Cabinet:

• 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.
• 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 baffle ensures a rigid, resonance-free mounting for all drivers.
• FEA-optimized ¾” (18mm) cabinet construction, bracing, and acoustic insulation eliminate acoustic and structural resonances, ensuring an inert enclosure and an uncolored response, even at the highest drive levels.
