In terms of overall appearance, both subwoofers present a clean, modern look that’s sure to fit into any home theater or multimedia setup seamlessly. However, there are some noticeable differences that set them apart.


First, let’s discuss the size. The SB-3000 measures 15.6″ x 15.2″ x 17.8″, making it a compact and space-saving option, while the SB-4000 comes in at 18.3″ x 17.8″ x 20.9″, which requires more space both in width and height.

The DSP engine allows precise tuning of crossover frequencies, phase alignment, and other essential parameters, ensuring optimal performance in any setup.

The control options on the two subwoofers differ slightly as well. The SB-3000 offers SVS’s convenient Bluetooth Control App, allowing users to control volume, phase, and EQ settings directly from their smartphones.

On the other hand, the SB-4000 boasts a more advanced Multi-Function Display on the front panel of the unit, providing quick access to settings and custom presets. While the differences in control options might come down to personal preference, it’s worth noting that both models still provide versatile and convenient controls to suit various user needs.
