Marshall Stanmore II Tweeter Assembly Replacement

Introduction

This guide is to be used for the replacement of one or both tweeter assemblies in the Marshall Stanmore II Bluetooth Speaker.

The tweeters produce high-frequency sounds in a speaker. These high-frequency sounds allow listeners to hear the treble in music. If a speaker has a malfunctioning tweeter, anything played would sound muddy and incomprehensible.

Before using this guide, make any adjustments for the treble and bass using the dials on top of the speaker or through the Marshall Bluetooth app. After adjustment, verify if the sound quality has improved. If there is no improvement, follow the troubleshooting steps on the Marshall Stanmore II Bluetooth Speaker Troubleshooting page before attempting to disassemble.

Step 2

Use a Phillips #2 screwdriver to remove the ten 20.5 mm screws that secure the rear panel to the chassis.

Step 3

Carefully lift the rear panel and let it rest on an object, like a stack of books, to avoid straining the cables.
Do not attempt to fully remove the panel, as this will damage the connections inside.
