This JBL loudspeaker pair is a great choice. There's a minor issue where the grills are rusty, but it doesn't impact the functionality at all.

Using these JBL loudspeakers is easy. Just connect them to your audio system as you normally would. When it comes to placement, try to put them in a position where the sound can spread evenly. As for the rusty grills, don't worry about it affecting the performance. But if you want to keep them looking good, you can gently clean the grills with a soft brush from time to time. Also, make sure to keep them away from moisture to avoid any potential damage to the internal components.
