SOUND QUALITY PERFORMANCE 89/100
Bass
90/100
Dual inward-firing 5"x8" elliptical woofers, ported cabinet and a spec'd response 'as low as 25 Hz' with dual Class-D amps suggest strong low-end extension, control and low distortion for the cabinet size.
Dynamics
88/100
Force-canceling inward drivers and dual tuned Class-D amps should deliver good transient control and low distortion; ported architecture also supports stronger LF output. No third‑party listening reports available to verify ultimate slam/headroom.

Integration
86/100
Automatic EQ, Trueplay room tuning and Sonos app controls provide the tools to integrate the Sub 4 with Sonos speakers, but these are feature claims rather than listening-outcome evidence. Features ≠ Integration; add outcome evidence or lower Integration.
Build Quality
90/100
Matte finish, solid 25.99 lb weight and a described unique acoustic architecture indicate a well-built cabinet and driver implementation consistent with Sonos' prior products.
Features Connectivity
92/100
Comprehensive connectivity and usability: Wi‑Fi (2.4/5 GHz/ax), 10/100 Ethernet, Sonos app control, Trueplay room tuning, automatic EQ, and a Join button make setup and network integration straightforward for Sonos ecosystems.
Value for Money
80/100
At $799 the Sub 4 is a premium-priced sub; it offers strong integration and features within the Sonos ecosystem but is not demonstrably 'best in class' for price without independent reviewer endorsements.
