Choosing a Subwoofer

Subwoofers are the speaker units that produce lower frequency sounds. It is a very important part of getting great sound. It ensures that the music’s bass is clear and hard hitting. Most human beings can hear between 20and 20,000 Hz. Subwoofers give out sound on the low end of this frequency scale.
The crossover filters of subwoofers filter out sound that is high on the frequency scale. The point where this takes place can be adjusted. Sounds on the low part of the frequency scale are very long and it takes a lot of power for them to be heard. By using a subwoofer to filter low-frequency sound, the base in your automobile will sound a lot better.
When you're looking for a subwoofer, it's important to decide ahead of time how much power you want. If you have a lot of room and you want a lot of base, then you will want to purchase a subwoofer that has powerful, built-in amplifiers. Also, it is important to note, that the bigger the driver is, the deeper the base will be. Therefore, you may want to go with subwoofer with around a 10 or 12 inch woofer cone.
Many subwoofers come with a single cone then moves back and forth to help create sound waves that are low-frequency. The woofer cone can be mounted one of two ways. The first way is called, down firing and the second is called front firing. Subwoofer cones that are down firing are typically on the bottom of the subwoofer cabinet. When they are front firing they are on the side of the cabinet. One of these is not necessarily better then the other. It's just a matter of design and your own personal taste.
Another important part of subwoofers is the enclosure. This is essentially the cabinet where the speaker is placed. By changing the design of the cabinet, you can affect how the subwoofer works and its’ output. There are a couple of types of enclosures. They are called acoustic suspension and base reflects. Acoustic suspension enclosures are inside a box and help to offer base response. The sound that you will get will be tight and accurate. However, it will take a more powerful amplifier then is required with the base reflects design. A base reflex enclosure has a port, which helps to make the base bigger and more extended. Essentially all of port is, is a hole that allows some of the energy created from the woofer cone to come out. These types of enclosures use power better, but they're not as accurate.
Subwoofers provide full, rich sound and a lot of base. If you have standing speakers, you may be satisfied with the base. However, if you want a little more power and a little more kick then you may want to consider adding better subwoofers. Also, if you are thinking of using your stereo system for a home theater or you just want really big sound, then you may want to consider getting or upgrading your subwoofers.
