Subwoofer Speaker
Subwoofer Speakers are the units that produce lower frequency sounds. If you want to get a great sound, you can try subwoofer Speakers. It ensures that the music’s bass is clear and hard hitting. Most human beings can hear between 20 and 20,000 Hz. Subwoofers give out sound on the low end of this frequency scale.
Many subwoofers come with a single cone then moves back and forth to help create sound waves that are low-frequency. 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. By changing the design of the cabinet, you can affect how the subwoofer speakers works and its’ output. Acoustic suspension enclosures are inside a box and help to offer base response. A base reflex enclosure has a port, which helps to make the base bigger and more extended. Subwoofer speakers provide full, rich sound and a lot of base. If you have standing speakers, you may be satisfied with the base.
Depends upon how well you want to hear deep bass, if your music or audio is reproduced under 40 Hz. Subwoofer drivers, known as woofers, average between 8″ and 15″, and can run 34″ even. Use high-powered amps with subwoofer speakers and an electronic crossover with a low-pass filter. There are two types of subwoofer speakers; those with an amp in the subwoofer cabinet (active), and those without the amplifier (passive).
With regards to the use of subwoofers in home theater systems, they come mounted in a sealed enclosure. Others build the subwoofer into the theater cabinet. Some people prefer to place the subwoofer speakers near the listener. Bottom line is, if you want to be able to hear low frequencies, you need a subwoofer.
Lower frequencies are needed with older sound formats, like with vinyl records replaced with digital formats, like CDs, mainly with 5.1 formats Dolby Digital and DTS (where the “.1″ channel is for the bass frequencies, for the subwoofer), common choice of mixed artists.
Get Great Bass Throughout Your Home Theater
It’s one of the hallmarks of a fantastic home theater; great bass. What too many people get is either weak, anemic bass or boomy bass that sounds like mud. In many cases you’ll have pretty good bass at one seat and little or no bass at other seats. To make bass you need to move the air in the room. If your room is larger, your sub must move more air to get the same effect as it would in a smaller room.
Most subwoofer speakers used similar designs, either a bass reflex (ported) or acoustic suspension (sealed) box. Most quality subwoofer drivers had somewhat similar excursion specifications. Most manufacturers will have recommendations about which of their subs to use in a given room size.
Now for the biggest key to getting great bass in your home theater; use multiple subwoofer speakers. One of the biggest problems in small room acoustics is caused by standing waves. For even better bass and smoother frequency response throughout your home theater, use four subwoofer speakers. Using the correct subwoofer speakers for your room and using multiple subwoofers with a good equalizer will help you get that spectacular bass your home theater has been missing.
