Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — wireless subwoofer (mains-powered): A mains-powered wireless subwoofer that pairs to a Bose soundbar to add deep bass. No battery and no standalone function — it only works paired to a compatible Bose soundbar through the Bose Music app.
Pairing: 'No bass / not working' is usually the wireless pairing to the soundbar: add it in the Bose Music app and confirm it shows connected. It must be assigned to a soundbar to do anything.
Placement & level: Bass level is set in the app; corner placement makes it boomier. Adjust the level and placement before assuming a fault.

Questions that only have an answer for the Bose Bass Module 700

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My Bose Bass Module 700 isn't producing bass.+

It only works when wirelessly paired to a compatible Bose soundbar, so confirm in the Bose Music app that it is added and shows connected, and that it has power. If it is paired but weak, raise the bass level in the app and check placement — a corner boosts bass, open floor is flatter. A module that will not pair at all usually needs to be reset and re-added, and kept within wireless range of the soundbar.

Structured depth, not empty permutations
