Introduction
Follow this guide to replace the woofer inside your MartinLogan Motion 4i model MO4IBL.
The woofer in a speaker generates low frequencies. A speaker with a failing woofer makes a fizzing sound.
You must have the back cover removed from the Speaker to start repairs. If you have already removed the back cover, please skip to step 7.
In step 9 you will need a soldering iron to take out 2 wires off the woofer.
Before beginning, the woofer is highly magnetic so keep your phone and other electronic devices away from it
