Product Description

A top choice for home theater and audiophile music systems, the SB-4000 subwoofer delivers massive SPLs and extreme low frequency extension that will astonish even the most discerning listeners. A high-excursion 13.5-inch driver unleashes immense sonic energy while maintaining pinpoint control and accuracy from a 1,200 Watts RMS, 4,000+ Watts peak power amplifier featuring fully discrete MOSFET output and analog devices most advanced audio DSP. Precise tuning for the SB-4000 is enabled from a subwoofer DSP smartphone app with custom presets.

Chest-thumping slam and low frequency extension below the threshold of human hearing, with refined musicality – a level of subwoofer performance not seen at this price before. The SB-4000 subwoofer’s sophisticated DSP amplifier, innovative driver and a sealed box design master room gain and command a space with deeper bass and higher output levels than what is typically possible from a subwoofer of its size. An ideal option for reference quality bass in audiophile music or home theater systems, the SB-4000 sets all performance benchmarks for a subwoofer and leaves larger and more expensive subs trembling in its wake.

The SVS SB-4000 powered subwoofer demolishes all preconceived notions about subwoofer performance and technology by taking command of any room with deep, effortless bass and adding visceral energy to every listening experience. With trickle down technology from the 16-Ultra Series, named top subwoofers in the world by nearly every audio publication and industry group in 2017, the SB-4000 obliterates expectations and delivers a level of unrivaled subwoofer performance only available from SVS.

Inlaid front panel display, rounded edges and a curved metal grille on the sealed box SB-4000 cabinet give it a refined yet commanding look that blends visually with home theaters and high-end audio systems. It’s sealed cabinet design results in tighter, more musical bass and make it significantly more compact than ported box subwoofers with similar specs.

13.5" driver with 3" voice coil (8-ply aluminum flat wire edge wound 3" voice coil), for ultra-low distortion, efficient heat dissipation, exceptional linearity and almost zero % power compression.

Double thick 2-inch MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment.

Highly reinforced internal design and acoustic insulation eliminates all coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference volume.

Protective, non-resonant steel mesh grille and custom elastomer feet for reducing noise artifacts within a room.

We also offer the matching SoundPath subwoofer isolation system with four feet.

Attention: We have other SVS subwoofer on offer.
