We all know what bass can do to a movie soundtrack. It can create drama, danger, even a feeling of strength depending on the visuals that go along with it. Bass is one of the most important elements of any audio format because it provides balance and contrast to the overall score of a movie, television show, even commercial. Quality bass in a sound system is impressive while not being overpowering.
In a 5.1 surround sound system, one of the most common 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 amount of air it takes to make these sounds. While smaller speakers can produce these lower frequency waves, they typically cannot produce the kind of quality that one would expect from a quality theater. Smaller speakers can often sound tinny when trying to produce these lower sounds. Large home theatre speaker towers are capable of handling this part of the soundtrack though it may require the reduction of sound quality from the mid and high range frequency speakers.
Choosing a good sound system with a quality bass speaker is not impossible, even for people who do not have a lot of experience. First, start with the subwoofer. Homeowners will need to consider whether they require a passive sub or an active woofer. A passive subwoofer does not need a separate power supply. Rather it uses power from the same amp that is driving the other home theatre speakers. Volume from the amplifier can usually be controlled, there is less control overall with a passive sub. An active sub has a separate 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 decide where to place the subwoofer, put it in the same position that you will be sitting in, whether it is on the couch facing the television screen or in a home theater chair. Turn on a favorite film then move around 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 around the room in roughly 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 generally block high sound frequencies from leaving the room, they can actually increase the volume of the lower range sounds. While laying out your speakers, try to also find the right volume balance for all frequencies that your family can enjoy the sound quality a bass can provide without driving your neighbors crazy.

The two things people love the most about satellite radio are: quality and content. These two things are also the very things that encourage people to go out and buy a new system. So what if it costs $300 for a satellite radio receiver, and another $13 per month for subscriptions. The benefits of satellite radio far out weigh the price!
High Audio Quality
Satellite radio quality is more than just the overall value of the product. It is also how clear, uninterrupted, and flawless the satellite signal is. This new technology provides all the radio you could possibly desire without messy static, and having to change the channel during a commute. The high analog-to-digital conversion means that you can listen to the radio without all that creepy hissing, dead air, and other frustrating audio interference.
The digital quality of the service, in technical terms, is 128kb/s 44.1 kHz. For you technologically impaired and non-number minded folks, that means that when you listen to it, it's like listening to a CD, only you don't have to mess with unwrapping it.
Almost Limitless Content
When digital television hit the market, people were scrambling over each other trying to get their hands on it. More of the same for satellite radio, but unlike its visual counterpart, this is commercial free. That means exactly what it sounds like; no one interrupts your listening pleasure to try and sell you acne cream or hypnosis.
Satellite radio content is more than just local radio stations pawning off what other people think is good music on you. With the new non terrestrial radio you can listen to what makes you happy, what puts you in a good mood, what suits you as a person. You don't have to listen to Hip Hop, Country, or R&B if all you want to hear is Sinatra and the Rat Pack. Content is also where the main two companies are fighting for your favor. XM may offer more of what you want to hear than Sirius, and/or vice versa. Before subscribing you should take the time to find out which one would give you more content for your buck.
Satellite radio is playing dirty. Each company is fighting for the exclusive rights to broadcast certain programs and transmissions on their radio systems. Not only are they fighting for programs, but also people!
Satellite radio is making great strides for its customers. The companies know that if you are willing to pay the money for a receiver, and then pay a month subscription fee, they should be willing to give you the absolute best programming they can offer. So why tie yourself down to earthbound radio stations when you can reach for the stars with the new technology?
Wireless headphones are good for any music junkie who wants to remain in the know of the greatest all-time hits. Are you longing for the perfect quality of sound from your headphones? Are you in search of the best wireless headphone? Have you been disappointed by any wireless headphone and want to get something that you will buy and never have to worry about the same disappointments again? There are several factors that you need to consider before you spend any more of your money on wireless headphones.
The main aspect of this headphone type is the fact that it is wireless. So, how will they work without plugging them into a device? Wireless headphones run on batteries. For moderate users who will not be using them often, the regular batteries will do. This is because they will best suit their needs without costing them much in terms of extra costs. However, for those who will be using these headphones throughout the day, rechargeable batteries should be considered. These rechargeable batteries can also be used on other devices therefore come in handy for long term use.
Another aspect that one needs to look at is the kind of connection that the headphones use. Generally, the entire ranges of wireless headphones are over-the-ear headphones. These are pretty chunky but there are some who will still want to use them outside. It is important to understand the connectivity of your headsets before buying them. This factor is important due to the fact that there are wireless headphones that do not have a large range. This means that if you go a little farther from them, you would be cut off from whatever you were listening to. Also, there are frequencies which can be interrupted by electronic devices or a television set being in between of the headphones and the devices being connected to.
What you need to look for the most in wireless headphones is the quality of sound. There are many wireless headphones for TVs which have different features that can adjust sound quality among other attributes. You need to be aware of these features.
In wireless headphones, do not just look at the quality of sound, but also look at the build quality. Do not look for headphones which will have you spend more than what you will gain from them. If you are going to spend a considerable amount of money on the headphones, then make sure they have superb sound quality and high-quality build. Don't just buy any headphones with a great sound but their build is flimsy and you feel like they can't last very long. Even if you feel like you are a very careful person, it is important to look out for durability when purchasing these headphones. A brand-name that is well-known can make you feel confident about the durability of a product but this is not always true. Ensure that the build is able to withstand wear and tear for a long time. It is important that you spend little to no time repairing headphones and more time enjoying great music from them. Get wireless headphones which you are comfortable with since you may be wearing them for long and you don't want headphones which will not make you keep scratching your head frequently.
Finally, you need to look at the price of the wireless headphones. Do not purchase headphones which will make you spend a lot of money and still give you less value. A lot of cash on a product should equal to high quality sound and a superb, sturdy build.
