One 16-inch sealed subwoofer, bass down to 16 Hz
The SVS SB16-Ultra Subwoofer is a sealed subwoofer built around a 16" Ultra-series driver and a 1,500 watt RMS Sledge amplifier. The sealed cabinet is designed for tight, accurate bass, with a quoted frequency response reaching down to 16 Hz. This is a single subwoofer, offered in Black Oak or Piano Gloss Black.
Why You'll Love It
- Reaches down to 16 Hz. The sealed design delivers a quoted response of 16 to 460 Hz ± 3 dB for deep, controlled low frequencies.
- Massive 16-inch driver. The Ultra-series driver uses an 8" edge wound voice coil, the largest SVS has fitted to a consumer subwoofer, for low distortion at high output.
- Full app control. The SVS smartphone app adjusts the DSP and stores presets over Bluetooth, alongside IR remote and front panel control.
Under the Hood
- 1,500 watt Sledge amplifier. The Sledge STA-1500D delivers 1,500 watts RMS continuous, 5,000+ watts peak, with discrete MOSFET output and Class D efficiency.
- Long-throw Ultra driver. Four ferrite magnets drive 78 mm peak to peak excursion on a cast aluminium basket, with dual shorting rings to lower distortion.
- Sealed, heavily braced cabinet. A double-thick MDF front baffle and rigid internal bracing keep the cabinet acoustically inert at high levels.
CHT Insider Verdict
The SB16-Ultra is a full-size sealed subwoofer for people who want deep, accurate bass rather than the loosest possible output. The 16-inch driver and 1,500 watt amplifier produce serious low frequency energy, while the sealed cabinet and DSP keep it tight and controlled. App, remote and front panel control make day-to-day tuning straightforward.
Pro Tip: Use the three parametric EQ bands in the SVS app to tame room-related bass peaks; because Bluetooth control works even when the subwoofer is out of sight, you can adjust levels from your listening seat.
