You’ve got two premium subs in view: the full‑size Sonos Sub (gen3 / now evolving to Sub 4) and the compact, budget‑friendly Sub Mini. Both deliver deep bass to your Sonos soundbar or speaker setup—but they don’t deliver it the same way. One overwhelms your space with power and presence; the other gives meaty performance in a smaller footprint. The trick is: which fits your space, your budget, and your sound goals?
Let’s make long story short: If your room is medium or bigger, and you want cinematic, room‑shaking bass the Sub (or Sub 4) is your winner. But if you’re in a smaller space, want clean, tight bass without overkill, and prefer a discreet design Sub Mini is compelling.
Why Do I Recommend Sub (Sub 4)?
- It uses dual Class‑D amplifiers + force‑cancelling woofers in a signature acoustic architecture to eliminate distortion and vibration.
- The newly announced Sub 4 upgrades the design—dual elliptical 5×8″ woofers, matte finish, same 25 Hz lower bound—while trimming weight and improving cabinet performance.
- Sub handles larger volumes, room filling bass, and performance demands that Mini struggles with in bigger rooms.
- It still gives you seamless integration via Sonos app, Trueplay tuning, and EQ balancing.
Detailed Comparison & Recommendation
| Feature / Spec | Sonos Sub (or Sub 4) | Sonos Sub Mini | Which Is Best & Why? |
|---|---|---|---|
| Drivers & Acoustic Design | Dual force‑canceling woofers, full sealed / ported cabinet, architecture for distortion control | Dual 6″ inward‑facing drivers in sealed cabinet with force‑cancelling design | Sub (or Sub 4) offers more pressure, more headroom; Mini delivers impressive performance but within limits. |
| Frequency Response | Down to 25 Hz in many settings (handles deep bass) | Also claims 25 Hz floor for many tracks | Tie on spec floor—real difference is output and control at volume. |
| Size & Placement Options | Bigger footprint (≈15–16 in tall / wide), heavier. Sub 4 supports vertical or horizontal placement. | Much more compact (12 in tall, 14 lb) and can hide discreetly. | Mini wins in small or crowded spaces; Sub gives you flexibility for volume and placement. |
| Performance in Rooms | Strong in large / open rooms, holds bass under pressure, cinematic impact | Excellent in small / medium spaces; in big rooms it strains under intense bass. | For big rooms or demanding audio finishing, go Sub; for smaller, Mini is serviceable. |
| Compatibility & App Control | Seamless Sonos ecosystem, app tuning, supports the latest Sub 4 connectivity. | Works fully in Sonos S2, app tuning, automatic EQ, but lacks some pairing options (e.g. can’t pair two Minis) | Sub wins in future expandability and pairing; Mini is adequate but limited in pairing multiples. |

Quick Summary
The Sub / Sub 4 is a powerhouse sub for those who demand rumble, depth, and cinematic bass in larger spaces. Sub Mini offers surprising performance in a smaller form factor—ideal for smaller rooms or systems—but can’t match full Sub output under load. Your choice depends on how big your room is, how loud you want to go, and how much space you want to dedicate to a subwoofer.
Final Verdict
If you’re building a home theater or want bass you feel, go Sub (or Sub 4). You’ll get durability, flexibility, and power you’ll appreciate for years. If you live in a moderate-size room, don’t need earth-shaking lows, and prefer sleek minimalism—Sub Mini is a strong pick.
