SVS SB-3000 R|Evolution Sealed Subwoofer

Reference bass from a sealed box

The SVS SB-3000 R|Evolution Sealed Subwoofer is a single sealed subwoofer built around a 13 inch high-excursion driver and a 1,200 watt continuous MOSFET amplifier. The sealed cabinet keeps the footprint tight and the bass controlled, so notes start and stop cleanly. A smartphone app puts tuning in your hands from the listening seat.

Why You'll Love It

• Serious output, tight control. The 13 inch driver and 1,200 watt continuous amplifier, with over 4,000 watts peak, deliver deep, high-impact bass while the sealed cabinet keeps it accurate.
• Tune from your seat. The SVS app controls volume, low pass filter, phase, polarity, six parametric equalisers and room gain over Bluetooth, with three memory presets for music, movies and night listening.
• Fits more rooms. The sealed design is more compact than a ported box with a comparable driver and amplifier, so it is easier to place.

Under the Hood

• High-excursion driver. A Flat-Edge Split-Wind voice coil and toroidal ferrite motor drive a rigid 1100 pure aluminium cone for clean output at high levels.
• MOSFET amplifier with DSP. The STA-1200D2 pairs Class D efficiency with discrete MOSFETs, managed by a 295 MHz Analog Devices DSP and premium DACs rated above 120 dB signal-to-noise.
• Balanced and unbalanced inputs. Connect through unbalanced RCA at 10 kΩ or balanced XLR at 18 kΩ, both handling up to 4 Vrms.

CHT Insider Verdict

The SB-3000 R|Evolution is aimed at listeners who want reference level output without the bulk of a ported subwoofer. The sealed cabinet trades a little ultimate depth for tighter, more musical bass, and the app makes setup far less fiddly than rear-panel dials.

Pro Tip: Save separate app presets for movies and music. A little extra output suits films, while a flatter setting keeps two channel music honest.
