Most of us understand that the subwoofer in a home theater system takes over the job of producing much of the deep bass energy from the other speakers in the system. “Deep bass energy” is defined as the deepest bass from 100 Hz down to almost subterranean frequencies of 20 Hz or lower.
But to be able to hear and thrill to those powerful bass frequencies depends a lot on the home theater subwoofer placement in the room. This occurs because the subwoofer interacts with the actual dimensions of any given room, creating zones of very powerful bass contrasted with areas where you’ll hear little or no bass. You may have noticed this if you walk around the room while deep bass is playing.
The trick to adding the “wow” factor back into your home theater system is careful placement of the subwoofer so that it “couples” to the room in a manner that generates reasonably smooth powerful bass in regions where your couch and chairs are located. That location may be quite different in different rooms, depending on the room dimensions.
How many of you have actually done the tests to determine the best place in your room for the subwoofer to perform optimally? I suspect you had the best of intentions, but given that subwoofers tend to be large, heavy and awkward to move about, I bet there are lots of us who just plunked the sub down at the front of the room and hoped for the best, never bothering to do the “subwoofer crawl”. You can read how to do this here. http://www.axiomaudio.com/tips_subwoofer_placement.html
Just for fun, let’s try a poll on A) how many of you never bothered to properly set up your subwoofer, or B) you should have done it years ago, but once you did, you were amazed at the improvement, or C) you’ll be doing it this weekend.
Home Theater Subwoofer Placement Poll
For starters, you could try putting your subwoofer into a corner. It might work well, but as often as not it just produces too much “boomy” bass. Placing the subwoofer next to a wall is important, because the wall in effect amplifies the deep bass output (the worst place for a sub would be in the middle of a room). After that, do the subwoofer crawl to find the exact location for home theater subwoofer placement in your room for ultimate home theater excitement.
