Score: 86/100Rankings

The SVS PB-1000 Pro is a ported 12-inch subwoofer delivering deep 17 Hz response with 325 W RMS power and extensive app controls. Port chuffing and limited headroom in very large spaces are potential drawbacks. Suited for apartments and medium rooms seeking high-output bass in a compact package.

The Klipsch SPL-120 is a 12-inch powered subwoofer that delivers tight, room-filling bass with up to 118 dB output, thanks to its 300 W RMS Class D amplifier. Its compact front-firing design limits bass extension below 24 Hz and requires careful placement. Ideal for medium-sized rooms and users seeking high output without a large footprint.

Professional reviewers commend the SPL-120 for its impressive 118 dB output, tight low-frequency response down to 24 Hz, and efficient Class D amplification that stays cool. They highlight the front-firing slot port and Cerametallic woofer as delivering clean, musical bass, and appreciate its compact size for corner placement. However, they note it falls short of the deeper output and refinement of larger 15-inch Klipsch models and the KEF KUBE 12B, and it may need careful crossover and positioning to avoid muffled bass.
Everyday users praise the SPL-120 for its powerful, room-shaking bass that remains tight and distortion-free, its easy integration with existing AV gear, and its attractive, durable finish. Common themes include appreciation for its compact footprint and efficient operation. Recurring complaints focus on the need for precise room placement and the limited sub-24 Hz extension, which some users find insufficient for extreme low-frequency effects.

“just big enough to be awesome”




Professional reviewers commend the PB-1000 Pro for its upgraded 12-inch driver, powerful 325 W RMS amplifier, and sophisticated DSP that together produce precise, high-output bass with low distortion. The ported enclosure and app-based controls are highlighted as refinements over the previous model, though critics note limited headroom for very large spaces and the lack of built-in room correction or a remote.
Everyday users love the sub's ability to deliver deep, tight, earth-shaking bass that transforms small rooms, praising the intuitive app for easy setup. Common complaints revolve around port chuffing without plugs, sensitivity to placement, and the unit's weight, with some wishing for more power in larger areas.
