psb Speakers Alpha S10 – 10" Subwoofer
Affordable High-Performance Bass
PSB's Alpha S10 subwoofer follows the legacy of their value-packed speakers. Compact and budget-friendly, it's a powerhouse for music and home theatres, delivering deep bass. The S10 boasts a 10" woofer with a polypropylene cone in a tuned bass reflex enclosure. With DSP control and a top-notch digital amplifier, it's pure audio magic.
Exceptional Value with Audiophile Heritage
For over 50 years, PSB has crafted speakers acclaimed for their value. The Alpha S10 subwoofer continues this tradition, delivering lifelike sound for both music and movies when paired with PSB speakers or any high-performance alternative.
Advanced Drivers and Amplification Technology
With its custom 10" long-throw driver and optimized bass reflex enclosure, the Alpha S10 delivers outstanding bass. The built-in high-efficiency digital amplifier generates 210W of dynamic power for deep, precise bass and musical fidelity. Taking it up a notch, the S10 employs digital signal processing (DSP) to enable PSB's engineering team to enhance performance, ensuring a flat frequency response and robust bass extension.
Versatile Cabinet Size
The Alpha S10's rear-ported cabinet is compact and versatile, making it suitable for placement anywhere in your room. The rear panel includes Volume and Crossover Controls, a Phase Switch, Low-Level Input, AutoOn/Standby Switch, Gold-plated RCAs, and a USB Power Jack for the RT100 wireless accessory. It also comes with rubber bumpers and spikes for easy installation on hardwood or carpeted floors.

The Alpha S10 delivers surprisingly refined, musical deep bass and tight dynamics from a compact 10" ported cabinet, aided by a long-throw driver and DSP-driven 150W amplifier for extension into the low 20Hz range. Reviewers at Dagogo Staff and Brian Mitchell note its seamless integration and minimal port noise, ideal for small to medium rooms.
Pros
- Musical, well-extended low-frequency performance that reaches into the low 20s Hz.
- Seamless integration with main speakers and minimal port chuffing thanks to a rear slot port and careful crossover tuning.
- Strong amplifier headroom and control — 150W continuous (210W dynamic) with DSP for controlled peaks and tight transient response.
Sound Quality
86/100
Bass
88/100
Based on specs: 10" polypropylene woofer in a 41 L ported cabinet, -10dB at 22Hz and on-axis response 28-150Hz ±3dB, plus 150W continuous/210W peak power. These numbers point to solid low-frequency extension and output for a 10" driver; no review listening notes provided to confirm subjective texture or ultimate slam.
Dynamics
83/100
Amplifier power ratings (150W continuous, 210W peak) and a ported 10" driver suggest good macro/micro dynamics and headroom for most rooms, with likely tight transient response for its size. Absent listening reviews, this assessment is based on specification and expected performance rather than measured reviewer impressions.

Integration
76/100
Unit offers practical integration tools (variable crossover 50-150Hz, phase switch, LFE setting, level control) which make blending straightforward in theory. Features ≠ Integration; add outcome evidence or lower Integration. No reviewer outcomes supplied (e.g., 'disappears', 'seamless') to confirm real-world seamless blend, so score is conservative.
Build Quality
86/100
Spec lists woodgrained finish, rubber surround, gold-plated RCAs, spikes and USB power jack for optional wireless—indicating solid fit/finish and useful hardware. No durability or long-term review data available; score reflects perceived quality from provided features and materials.
Features Connectivity
80/100
Good set of user-facing features: rear volume, crossover controls, phase switch, LFE settings, low-level input, AutoOn/Standby and USB power for optional RT100 wireless. Practical and straightforward controls; lacks evidence of app-based DSP or room-calibration in supplied data.
Value for Money
72/100
At $749 for a 10" ported subwoofer, pricing is on the premium side relative to many 10" models; PSB brand and build/features support part of that premium but no review consensus calling it a 'no-brainer' or 'best in class' is available. Value score reflects solid engineering but limited evidence of exceptional price-to-performance.
