I’ve spent thousands of hours polishing cars...
Novus plastic polish #2 works well to remove swirls and # 1 works well to polish. These have less chemicals than meguirs etc. and in my oppinion are better to use on speakers where you want to takecare around drivers.
Griots Speed shine is my go to, to maintain a nice reflective surface. Remember than any dust will make swirls so wipe it off carefully with a damp cloth before doing any polishing.
For cleaning drivers, again a lightly damp cloth, no chemicals, no rubbing alcohol, and be gentle. A soft paint brush works well also.
