Went do you use the foam port plugs?

[titan7]

I have Energy RC-10s, the come with a foam plug? what is the reason for the plug? Is it better to use it or not? I have the speakers on top of the entertainment center, the back of the speaker is about 3-4" from the wall.

thanks for any insite.

They give them to you as an option. They alter the sound slightly. You can either use 'em or not but in either case, the speakers will perform just fine and no damage will be incurred.

Try it both ways. In and out. Whichever way sounds "better" to you is your answer.

The port plugs will alter the frequency response curve of the speaker. When you plug the port, you generally decrease the amount of bass, in favor of extending the curve further into the bass range. In other words, the bass will likely go deeper, but at a diminished level overall. If you have the ports in the back of the speaker, port plugs will also help with positioning because you can mount the speaker closer to the wall and you won't get the wall reinforcing the noise from the port.

The plugs can be used individually (e.g. one speaker near a corner) or together if you find the bass to be on the boomy side. They can also help tighten the bass performance a little. This graph shows how the bass response changes with and without the foam plugs on a Tannoy Monitor on test.

[Thanks guys!

you may find plugging the ports makes integrating your speakers with a subwoofer a bit easier. That's when I plug ports.
Be careful though, power handling does change significantly in the lower frequencies. If you're the type who likes the volume knob at max, just use some caution.

Plug in the speakers mean potential problems at high volume or when the plugs are out?
