Getting the most out of your home theater

[MrRoy]

I debated on creating this thread, and if it is already somewhere, please point to it. I wanted this to be kind of like a brain dump of the little things that people do to get the most out of their home theaters. An example would be putting "stuffing" in ports in speakers to tighten up the bass, that kind of stuff.

So, those of you that can contribute, please do.

Thanks!
