Know before you buy
The larger 13.5-inch high-excursion driver is designed to move significantly more air, allowing it to reach deeper, more visceral low-frequency notes that smaller drivers simply cannot reproduce. This results in a more impactful, cinematic experience for home theaters and a tighter, more authoritative foundation for music.
The Sledge amplifier uses a fully discrete MOSFET output, which provides the high current needed to maintain absolute control over the driver. This ensures that even at high volumes, the bass remains clean, punchy, and free from distortion.
Yes, SVS provides a dedicated smartphone app that allows you to control all DSP settings, including volume, crossover frequencies, and custom EQ presets. This makes it easy to calibrate the subwoofer from your listening position to ensure it integrates perfectly with your room acoustics.
It is engineered to excel at both. The advanced Analog Devices DSP ensures the subwoofer is fast and accurate enough for nuanced music playback, while its massive output capabilities provide the deep, room-shaking bass required for demanding movie soundtracks.
The finishes are purely aesthetic and do not affect the sonic performance of the subwoofer. Premium Black Ash offers a more understated, matte-textured look, while Piano Gloss Black provides a high-end, reflective surface that stands out in a modern media room.
