Bose Bass Module 500 vs 700
Same design language, same wireless pairing, same glass-top finish on the 700 — but under the fabric these are different animals. The honest summary: the 500 is a warmth module, the 700 is a home-theatre subwoofer. Here's how to pick.

What the differences mean in practice
- Depth: the 700 reaches meaningfully lower. Film effects that the 500 merely suggests — impacts, engine rumble — the 700 reproduces physically. For music at moderate levels the gap narrows considerably.
- Room size: the 500 is sized for small rooms and apartments; in an open-plan space it runs out of authority. The 700 holds composure in medium and larger rooms.
- Neighbours: the 500's smaller output and sealed design make it the safer shared-wall choice — see our apartment guide for why that matters more than specs.
- Placement: both are wireless and compact, but the 500's 10-inch cube disappears almost anywhere. The 700 wants a little breathing room to avoid boom.
The verdict
Buy the Bass Module 500 for apartments, small rooms, music-first listening, or when the budget is better spent elsewhere. Buy the Bass Module 700 for a Smart Soundbar 700/900/Ultra in a proper living room where movie nights matter. And if you don't own the Bose soundbar yet, price the bundle first — it's routinely cheaper than adding a module later.
Frequently asked questions
Is the Bose Bass Module 700 worth the extra money over the 500?
In a medium or large room, or if movies are the priority — yes, the 700's larger driver and port deliver clearly more depth and impact. In a small living room or apartment at moderate volumes, the 500 gets you most of the experience for roughly half the price.
Do both modules work with the same Bose soundbars?
Both pair with the Bose Smart Soundbar family (600/700/900/Ultra) and the older SoundTouch 300. They pair with one soundbar at a time and can't be combined with non-Bose systems.
Can I use two Bose bass modules together?
The Bose ecosystem supports one bass module per soundbar system. If you're tempted by two modules for even coverage, that's the point where a conventional receiver-plus-subwoofers system serves you better.
