Bluesound PULSE SUB+: Slim, Wireless HiFi Subwoofer

Deep bass is where audiophile ambition most often collides with physics. The Bluesound PULSE SUB+ is designed to resolve that tension with a subwoofer that is tight, quick, and musical—equally at home in a HiFi-focused stereo system or a home theater setup.

Acoustically, the SUB+ follows Bluesound’s HiFi heritage: an 8-inch driver powered by a 150 W Smart DSP amplifier in a carefully engineered, inert enclosure. With BluOS built in, setup and tuning are handled in software: the BluOS Controller app lets users pair the SUB+ with any compatible Bluesound component and adjust volume, crossover, and phase with precision rather than guesswork. That combination of smart control and solid engineering helps the SUB+ integrate cleanly into a wide range of systems and rooms.

Physically, the PULSE SUB+ challenges the idea that a subwoofer has to be big and visually dominant. Its slender cabinet—CNC-machined from high-density fiber and finished in Black or White—measures roughly 18" x 5.75" x 11.8" and weighs 18.25 lb, allowing it to sit flat under a sofa, stand vertically behind or beside furniture with magnetic feet, or mount on a wall using the included bracket. Wireless connectivity further reduces cable clutter and placement constraints.

With its combination of BluOS intelligence, compact, flexible geometry, and controlled, dynamic low end, the PULSE SUB+ becomes a genuinely meaningful upgrade to almost any entertainment system—adding depth and emotional impact without taking over the room.
