Rating for [object Object]

Nicely Roasted

The SubSeries 250 delivers authoritative, well-controlled low end that extends to the mid-20Hz range, pairing a 10" driver and 200W amp for punch without boom. Reviewers from Audioholics and ecoustics praised its musical integration and room-friendly sealed design, highlighting tight bass and controlled dynamics that suit both music and home theater.

Audioholics

"PSB may have an established reputation for delivering performance and value, but the company has some serious competition in the affordable subwoofer category."

Pros

  • Authoritative, well-extended low-frequency response (~25Hz on-axis) for a sealed 10" sub.
  • 200W amplifier paired with a 10" polypropylene driver yields punchy, controlled dynamics.
  • Competitive value at its MSRP ($699 for the 250), offering solid performance for the price class.

&

Cons

  • Stronger or cheaper alternatives from specialists (SVS, Hsu, RSL) mean this isn’t the uncontested best value in its segment.

Sound Quality

91/100

Bass

91/100

Reviewers repeatedly note strong, authoritative low-frequency performance: "no issue shaking my teeth loose" and "shaking the tchotchkes" (HomeTheaterHifi). Spec sheet supports solid extension for a sealed 10" (25Hz @ ±3dB, -10dB to 20Hz). Given sealed 10" limitations, score is high but stops short of reference-class claims.

Dynamics

90/100

Reviewers report confident dynamic behavior and control: the setup was "unfazed by Sunn O)))'s... MAXIMUM VOLUME" and conveyed material "with precision" (HomeTheaterHifi). The 200W Class-D amplifier and reported headroom support responsive macro- and micro-dynamics for its size.

Integration

90/100

Outcome-focused evidence shows the sub blends well with speakers: "The lows of the subwoofer served as a firm base to be built on by other elements of the set" and the setup "possessed a clean sound...not disturbing the listener" (HomeTheaterHifi). These phrases indicate successful, musical integration in listening systems.

Build Quality

88/100

Solid cosmetics and protection noted: "beautiful black gloss finish" with a "soft, meshy screen covering the 10-inch driver" that protected it from bumps (HomeTheaterHifi). Construction appears well executed for the price class.

Features Connectivity

84/100

Includes expected, useful controls: variable crossover (50-350Hz LR4), volume, phase, LFE input, auto on/off and a 200W Class-D amp (specs and reviews). No advanced DSP/approom-correction reported, so usability is good but not cutting-edge.

Value for Money

86/100

At MSRP $699 (Audioholics) reviewers call it reasonably priced and note PSB's reputation for value; HomeTheaterHifi described the system as affordable. Competitors (SVS, Hsu) and cheaper options (RSL Speedwoofer $399) exist, so value is strong but not unbeatable.
