Use tweezers to lift the adhesive pull tab at the top of the right speaker enough that you can grab it with your fingers.

Grab the adhesive strip pull tab and slowly and carefully pull the adhesive strip out from under the speaker.

Keep the angle of the adhesive strip as parallel to the laptop as you can. Try to avoid dragging it across the inside of the case.

If the adhesive strip breaks, or if the first adhesive strip broke, use a heated iOpener or heat gun to help remove the adhesive:

Apply heat to the speaker to soften the adhesive underneath.

Carefully slide a spudger or opening pick underneath the speaker to separate the adhesive.
