The Sub Mini delivers surprisingly muscular, well-controlled low end with a quick, punchy transient character from its sealed cabinet and opposing woofers without cabinet rattle. Reviewers like What Hi‑Fi? and ecoustics praise its controlled bass, quick dynamics and Trueplay/app tuning, making it a compact way to add cinematic scale to small-to-medium rooms for film and TV.
Pros
- Deep, controlled bass extension (down to ~25Hz) with no cabinet buzz or rattle, delivering impactful low end for movies.
- Quick, responsive dynamics and transient control that outperform many soundbar subs, giving punch and clarity to low-frequency hits.
- Feature-rich Sonos integration — Trueplay room tuning, app EQ, Wi‑Fi/Ethernet and easy setup — pairs especially well with Beam Gen 2 and Arc.

Cons
- Price weakens value: launch cost is high relative to the speakers it’s designed to supplement.
- Pairing can be uneven — some soundbar combos (notably the Ray) show a lumpy crossover, and music can sound a little one-dimensional.

Bass
86/100
Reviewers note dual opposing 15cm woofers and a sealed cabinet delivering extension to about 25Hz and a ‘quaking depth’ for film. However, music lacks 'shape or texture' and can be 'one-dimensional', so bass is controlled and potent but not reference-class in detail.
Dynamics
88/100
Described as 'quick, responsive' and superior to the 'loose, bland vagueness' of many soundbar subs, the Sub Mini delivers lively transient response and good slam for its size. SPL and prominence vary across the range, so dynamics are strong but uneven at some frequencies.

Integration
84/100
The Sub Mini 'feels the most solidly integrated' with the Arc and 'gains the most' with Beam Gen2, and overall can 'combine easily with a variety' of Sonos speakers 'without drawing attention to itself'. There are pairing hiccups (Ray pairing was 'least successful' and created a 'lumpy' crossover), so integration is mostly good but depends on the partner speaker.
Build Quality
82/100
Build is generally 'sturdy' and there are no rattles or buzzes, but reviewers flagged a slightly 'insubstantial, cheap feel' to the top plate. Overall construction and finish are solid for a compact sealed sub.
Features Connectivity
89/100
Includes Sonos app control, Trueplay room tuning, adjustable bass/EQ/phase, Wi‑Fi (2.4/5GHz), Ethernet, and automatic linked volume — all usable tools. Limitation: only one Sub Mini can be added per room and some pairing combos need careful level/EQ adjustment.
Value for Money
62/100
Launch price £/$429 is noted as problematic: reviewers call it 'disappointing' that the Sub Mini is 'the same price, or more expensive, than all the products it is designed to supplement.' Good performance for small spaces but price weakens value proposition.
