How can I mount speakers on drywall?

You need drywall mollies.

@Eambos

So I take the molly and just use it like a regular screw, but add the step of tightening the wedge thing?

drywall anchor

For something of small to medium size, you use plastic mollies that get punched into the wall. You then screw into them. For something heavy, it requires metal drywall anchors, which are a little harder to install.

Go to your local hardware store and tell them re weight of the speakers. They’ll be able to tell you which mollies you need.

Please clarify heavy, these are 5–10 lbs (I’m thinking closer to 5)

Edit: Sorry didn’t see your last sentence there.

You can always put a screw into the wall up by the top plate (on the wall, just as close as you can get to the ceiling). You will find continuous wood there, all along the top of any wall. Then you can hang the speakers from wires.

When you remove these screws later, you will have only small holes to fill, and those holes will be barely noticeable. Good solution if you are living in a rental.
