Home Theater Speakers - More About Subwoofers

We all know what bass can do to a movie soundtrack. It can create drama, danger, even a feeling of vigor depending on the visuals that go along with it. Bass is one of the most prominent elements of any audio format because it provides equilibrium and variation to the broad score of a movie, television show, even commercial. Quality bass in a sound law is impressive while not being overpowering.

In a 5.1 surround sound system, one of the most tasteless for home theater installations, the '.1' is the bass. The speaker for the bass sounds on a soundtrack is called a subwoofer. Lower frequency sound waves use a larger diaphragm to move the whole of air it takes to make these sounds. While smaller speakers can furnish these lower frequency waves, they typically cannot furnish the kind of Quality that one would expect from a Quality theater. Smaller speakers can often sound tinny when trying to furnish these lower sounds. Large home theatre speaker towers are capable of handling this part of the soundtrack though it may need the discount of sound Quality from the mid and high range frequency speakers.

Choosing a good sound law with a Quality bass speaker is not impossible, even for habitancy who do not have a lot of experience. First, start with the subwoofer. Homeowners will need to consider either they need a passive sub or an active woofer. A passive subwoofer does not need a detach power supply. Rather it uses power from the same amp that is driving the other home theatre speakers. Volume from the amplifier can normally be controlled, there is less control broad with a passive sub. An active sub has a detach power supply. This means that the signal received from the amplifier/receiver is enhanced by the subwoofer itself, without taking any of the power from the other speakers.

Once you have your home theater subwoofer and other speakers picked out, lay them out to get the best sound from each. Bass sound is omni-directional, meaning that it goes out from the speaker in all direction. To rule where to place the subwoofer, put it in the same position that you will be sitting in, either it is on the couch facing the television screen or in a home theater chair. Turn on a favorite film then move nearby your room and listen. Find the spot that the bass sounds best and move your subwoofer to that location. It can be set on the ground, on a shelf or off of a wall depending on where you feel the best low tone sound is heard. Since the sounds are going out and bouncing nearby the room in practically the same direction, the sound should be great when you get it into place.

We've all heard the laments of mothers and fathers forced to deal with the incessant thumping and pounding of boom box bass lines from their adolescent's car or room. There is something to say for the potential for this phenomenon to occur in a home theater as well. While walls, ceiling and floor will commonly block high sound frequencies from leaving the room, they can easily growth the volume of the lower range sounds. While laying out your speakers, try to also find the right volume equilibrium for all frequencies that your house can enjoy the sound Quality a bass can provide without driving your neighbors crazy.
