SVS SB-1000 12″ Sealed Subwoofer 700W Peak! – Like New, Boxed – Piano Gloss Black finish

The SVS SB-1000 is a compact, acoustically refined 12-inch sealed powered subwoofer that has earned a reputation as one of the finest entry-into-serious-bass subwoofers available at any price — delivering tight, articulate, deep low-frequency performance from a genuinely modest footprint.

Part of SVS’s celebrated SB-series sealed subwoofer lineup, the SB-1000 pairs a 12-inch high-performance driver with a 300-watt RMS / 700-watt peak Class D amplifier in a compact sealed-enclosure cube. The sealed (acoustic suspension) design delivers the fastest, most transient-accurate bass of any subwoofer topology, making the SB-1000 as enjoyable for two-channel music as it is for home theatre duty. Extension reaches down to 24 Hz — remarkable from a cabinet this size — with clean, composed output at both modest and enthusiastic listening levels.

The rear amplifier panel is thoughtfully equipped with a continuously variable low-pass filter (with defeat option for use with processor crossover management), continuously variable volume and phase controls, a 3-position line-level vs. LFE input mode, and both line-level (RCA) and speaker-level inputs for flexible integration with any receiver, integrated amp, or processor. Auto on/off standby circuitry keeps idle power consumption minimal.

The Piano Gloss Black finish is the premium option in the SB-1000 lineup — a high-gloss, lacquered surface with depth and lustre that presents beautifully in any listening room. This subwoofer is in like-new cosmetic condition and comes complete in its original retail box. It has been thoroughly inspected and tested to confirm full functionality.
