Rating for [object Object]

Nicely Roasted

The SubSeries 350 delivers tight, controlled bass with deep extension down toward 20Hz from a sealed 12" driver, driven by an efficient Class D MOSFET amplifier. Reviewers note its compact, premium build and flexible tuning — variable crossover and phase — that make it musical for both music and home theatre, according to Marc Rushton.

Pros

  • Sealed 12" design delivers tight, accurate low-frequency performance with extension toward 20Hz.
  • Efficient Class D MOSFET amplifier with smart limiting provides solid headroom and low standby power.
  • High-gloss, compact cabinet and robust driver construction give a premium fit-and-finish for a compact footprint.

Sound Quality

87/100

Bass

88/100

Sealed 12" with spec'd LF cutoff -10dB at 20Hz and on-axis ±3dB down to 25Hz suggests strong low-frequency extension and controlled output for a sealed design; heavy magnet and 50mm voice coil indicate good motor strength.

Dynamics

86/100

300W continuous (400W peak) amplifier with a substantial 50oz magnet and 50mm voice coil implies solid transient control and headroom for a sealed 12" sub; sealed design typically yields tight, controlled dynamics.

Integration

76/100

Features ≠ Integration; add outcome evidence or lower Integration. The unit offers a variable crossover (50-350Hz), variable phase and level controls which enable careful blending (specs: Variable Crossover Control; Variable Phase Control), but no reviewer outcomes are provided to confirm 'seamless' or 'invisible' integration in-room.

Build Quality

88/100

Hefty net weight (43 lb), 50oz magnet and 50mm voice coil point to robust driver construction; high-gloss finish reported in specs indicates a premium exterior, suggesting good overall build and fit/finish.

Features Connectivity

80/100

Includes volume, variable low-pass (50-350Hz, LR4), variable phase, auto on/off and LFE input (specs list). No advanced app control, room correction, or wireless options are listed, so features are solid and practical but not cutting-edge.

Value for Money

78/100

At $1,299, the spec set (20Hz -10dB, 300W continuous, sealed 12") positions this as a premium but reasonably priced option for audiophile sealed subs; without reviewer verdicts calling it a 'no-brainer' or 'best in class,' value remains good but not exceptional.
