Know before you buy
The S/510 is specifically engineered to bridge the gap between high-fidelity music and cinematic impact. Its PerfectFilter circuit ensures that deep bass doesn't muddy the mid and high frequencies, maintaining clarity for music while providing the necessary power for film dynamics.
This radiator design allows the subwoofer to behave like a sealed box at lower volumes, providing tight and accurate bass. As you increase the volume, the radiator's stiffness changes to allow for greater excursion, ensuring you get high output without losing control at the limit.
Yes, the S/510 features dedicated inputs for both. You can connect your main speakers via the High-Level Neutrik Speakon for music and your processor's LFE output simultaneously, allowing the subwoofer to handle both signals independently.
The S/510 is designed to be stacked in 4- or 6-unit line arrays. This configuration creates a floor-to-ceiling sound source, which significantly improves the scale and spatial imaging of your audio, providing a more panoramic and immersive experience.
The S/510 provides a low-frequency extension of -6 dB at 20Hz. This capability ensures that you can feel the deepest sub-bass notes in both demanding film soundtracks and complex musical arrangements.
The 500-watt RMS Class D amplifier is designed with substantial power reserves to handle rapid transients and high-output demands. While it is powerful enough for most medium-to-large rooms, its performance is best realized when paired with high-quality speakers that can match its speed and accuracy.
