Subwoofer placement can take some time.

Here is 1 trick:

- Get a long RCA cable and put the sub in place of the primary listening position.

- Disconnect all speakers except the sub

- Fire up a bass heavy CD or chapter in a DVD.

- Go to the corner of the 2 longest un-broken walls.Work along the longest wall and listen. There will be spots where the bass is boomy/rough. Other spots will be smooth and tight. Mark the tight spots with a postit or bottle of beer.

- Replace your chair, put the sub in one of the marked spots. Hook up the other speakers and sit and listen. Move the sub a few inches if needed.

- If the spot does not work, try the second or third as needed.

This uses both the law of reflection and the concept of "corner loading" to get the most wall reflection without bad interaction.

Hi.In my opinion two subwoofers are better than one.The reason being is that the subwoofer is an extension of the bass frequencies of your two main left and right stereo speakers.This will balance the sound of those speakers.Also you can buy a pair of stereo speakers that have woofers that can go down to 15 or 20 HZ.meaning a separate subwoofer is not needed. This would be a better arrangement although expensive.

Anyway back to your question. Real subwoofers are speakers that supplement the main speakers and only play the lowest frequencies (the lowest two octaves below 80HZ.)Good subwoofers don't play that muddy one-note-bass.They are clean and clear and you can easily follow the bass line in music.

A lot of wrong information is given out about subwoofers ,such as : bass isn't directional, you only need one subwoofer,or you can put it anywhere. Lets set the record straight :bass is directional in a room - the room causes it to be directional.To integrate subwoofers properly into a system you must place the subwoofer at the same end of the room as the main speakers.To make the bass less directional and blend better you need to cross it over at a low frequency and ideally use a pair of subwoofers.Only the very lowest frequencies are not directional.

The worst place to put a subwoofer is in a corner of the room.The sound would be unbearable.The next worst place is against a wall,which will also augment the bass. the best place is at least 3 feet out from adjacent and rear wall ,next to your stereo speakers which also should be at least 3 feet away from all surfaces. If the subwoofer is poorly made it would benefit from a corner position but this is propping up a bad design.Hope this helps.
EDIT..
I expect to get "thumbs down" about my comment that the room forces the bass to be directional. The only way bass can be omnidirectional is in an open space where the sound radiates out in all directions with no barrier to reflect it.It would be like a pulsating sphere. Or like when you through a stone into a pond ,the waves spread out in all directions.Once you put a barrier up the waves will stop and change direction.

The best place to get the maximum sound quality of a subwoofer is in a small space, but be careful and make room for air to move around. If you are getting distortion move it to a bigger area. but always remember the tighter the spot the harder the hit.
