Introduction
This guide is intended to replace the subwoofer in the Marshall Stanmore II Bluetooth Speaker.
The subwoofer produces the low-frequency sounds in a speaker. Low-frequency sounds--or bass--are what allow the listener to feel the richness and depth of music. Without bass, anything played through the speaker would sound tinny and mechanical.
Before using this guide, check the adjustments for the bass and treble using the dials on top of the speaker or through the Marshall Bluetooth app. Adjusting these configurations usually fixes any sound quality issues one may come across when this problem arises. If adjusting the bass and treble doesn't solve the issue, follow the troubleshooting steps on the Marshall Stanmore II Bluetooth Speaker Troubleshooting page for more possible solutions before disassembling the device.
Before removal, take note of the magnet that is on the subwoofer. Try to keep magnet-sensitive items concealed, or away, during removal.
