Real buyer questions on room & calibration, answered in plain terms.

Where should I place my subwoofer?

Not "wherever it fits". Placement changes a subwoofer's performance more than the model you chose, and it is the one upgrade that costs nothing.

How much does my room affect the sound, really?

More than any single component. If I had to rank what shapes the sound you hear, the room comes first and the speakers second, with the electronics some way behind.
