Denon’s naming makes it feel like these are minor variations, but the day-to-day experience can differ—especially around bass and room fit. If your priority is whether the S316 is the right pick overall, start with the Denon DHT-S316 review. This post is the head-to-head decision guide.
Quick recommendation (pick one fast)
- Pick DHT-S316 if you want a more “subwoofer feel” in a medium lounge and don’t mind managing placement.
- Pick DHT-S217 if you want simpler setup and less clutter, with more “all-in-one” convenience.
Bass approach: the biggest difference
DHT-S316
Typically chosen by people who want stronger low-end presence (and are willing to position the sub properly).
DHT-S217
Typically chosen by people who prefer fewer boxes and less setup complexity.
Connections and TV compatibility
In practice, compatibility is less about specs and more about whether your TV’s ARC behaves reliably. If ARC is flaky on your TV, optical is often the stable path—regardless of model.
Room size fit (UK flats vs lounges)
Small room
Prioritise clarity and easy control. Over-powering bass can be more annoying than fun.
Medium lounge
The S316 can feel more “cinema-like” if the sub is placed well.
Verdict: which should you buy?
If you’re reading this because you’re leaning S316, don’t buy blind—read the DHT-S316 pros and cons first so you know what you’re trading off.
