Overall Score 88/100

Nicely Roasted

Weighty, room-filling deep extension is the Sub 4’s headline: dual inward-firing, force-canceling woofers, a ported cabinet and dual Class‑D amps deliver controlled extension to around 25 Hz. Sonos’ Trueplay and automatic EQ smooth integration with Arc and Five, while reviewers like Best of High End and Marc Rushton praise its punch, build and seamless connectivity.

Pros

Deep, controlled low-end extension down toward 25 Hz from dual force‑canceling inward woofers, a ported cabinet and tuned Class‑D amplifiers.
Tight Sonos ecosystem integration — Trueplay, automatic EQ and app-based setup make pairing with Arc/Five straightforward and reliable.
Solid build and matte finish that complements living-room setups while minimizing cabinet vibration and visual clutter.

Sound Quality

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.
