MartinLogan Motion 4i Folded Motion Tweeter Replacement

简介

Follow this guide to replace the Folded Motion Tweeter found inside your MartinLogan Motion 4i Speaker.

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.

You will also need a Soldering iron to replace the Tweeter. Please be responsible with this tool and learn how to properly handle it before continuing. Unfortunately, we as students do not have access to a working soldering iron for this project so we are limited in what example pictures we can list.

    • Place the device face-down, then lift off the back case with both hands.

    • The speaker sometimes takes a little effort to remove the speaker back, so we recommend that you give it a couple shakes by placing each hand on the speaker face and the back when shaking.

    • If you decide to use the shaking method, make sure you're near an immediate surface near you just in case it drops.
