This can be done at home in minutes with just a screwdriver.

Follow the video and step-by-step guide below. 

Remember to check speaker cabinet fit before buying.


IMPORTANT: Always turn off, unplug and let your amp rest before opening it up. Amp capacitors may contain undischarged current that could kill you. Leave it unplugged for at least 2 hours to be safe.

Never, ever, work on an amp while its connected to power.

IMPORTANT: Never turn on an amp without speakers connected. The absence of a speaker impedance load could damage your amp head.

Also Important: the speaker magnet can be very strong, so remove any objects that can be damaged eg. your watch, jewellery.

1) Unscrew the back panel screws

2) Slowly remove the back panel....

Most cabs, and some combos, have the back panel connected to the speaker. In this case the speaker terminals must be disconnected, by reaching in with your hand, while the panel is being slowly lifted off.

If its a conventional combo, you can disconnect the terminals separately, after removing the back panel completely. 

In either case, note how the terminals were connected first. Take a picture.

(Red goes on +ve terminal, usually on the left)

3) Unscrew the mounting screws securing the existing speaker.

4) Slowly remove the existing speaker. If your combo has a reverb tank, you may have to unscrew and remove it first.

5) Carefully position your new speaker by lining up the mounting holes. Take care not to touch the speaker cone (front and back), when handling it. Make sure the terminals are positioned the same way too, usually up.

6) Replace the mounting screws, tightening them snugly to avoid rattle.

Unlike in the video, I suggest doing this by hand using a screwdriver and not a drill.

This will minimise the risk of damaging the frame by overtighening, or damaging the speaker cone by bumping the drill into its reverse face.

If you had removed a reverb tank in step 4, replace it now.

6) Attach the connectors to the new speaker terminals in the same way that they were connected on the old speaker.

7) Replace the back panel and screws.

8) 🤘
