Car owners and manufactures often add the car subwoofers with the car audio system to enhance their performance and to take them to a new level or sound excellence. In fact the subwoofers are complete loudspeakers that are dedicated to reproducing bass audio frequencies. The frequencies range from 150Hz to as low as 20Hz depending on the taste and requirements of the user. They are called subwoofers since they are used for augmenting the low frequency performances of any of the main speakers.

A unique feature of the subwoofers is that they are constructed by mounting woofers one on another and enclosing them inside well-braced cover that is either made of plastic or wood. They are available in multiple designs and are widely used to enhance the performance of the car stereos of any type. Main designs are bass reflex, horn-loaded, band pass, and infinite battle types. Of course each of the types has its own pros and cons to deal with.

Broadly the subwoofers can be classified into two types. One of them is the passive subwoofers and the other is active subwoofer. Passive subwoofers consist of the subwoofer driver. The enclosures will be powered by an external amplifier. On the other hand the active subwoofers have an inbuilt amplifier in the subwoofer. Way back in the 1960s the first subwoofer was developed for providing the addition of bass response to the home stereo systems.
Sensurruound was added during the 1970s. Compact discs and cassettes added further technological excellence to the subwoofers during the 1980s. DVDs arrived in the 1990s and with them came up the LFE or low frequency channels. That was the time when the subwoofers started gaining popularity for home videos and car stereos. It turned out to be the universally accepted sound reinforcement system by the time the new millennium arrived on the scene.

Numerous qualitative subwoofers that are used for the car audio and stereos are available in the market today. Recently the Infinity Systems, one of the units of Harman International Industries announced their new line of subwoofers. Many other leading brands and companies are following suit. Advantage of the modern day improved subwoofers is the industrial designs and the value price added to them. Today the subwoofers use large-roll surrounds, polypropylene cones as well as progressive spiders in them. In result they have gained optimal control of the sound system and made the bash sound effects free from distortions and also prevents sound from breaking down while delivered. The progressive spider applies increased force with the cone travel approaching its limits. In result the subwoofer gains much greater durability. Large roll surroundings help the cone edge maximum suspension eliminating any rattling that travels up the edge. Polypropylene cone is stiff despite being lightweight and thus provides an excellent balance of efficiency with power handling.

Many people are investing a lot nowadays to enjoy the perfect music experience. Be it at home or in the car, having an excellent music system has become essential. In addition to amplifiers, high quality music systems are also equipped with subwoofers these days. The subwoofer is a component that enhances the quality of the sound after it passes through the amplifier. Thus, having a good subwoofer as part of your complete music system is imperative.

Power bass subwoofers are one of the best in the market. Like most top of the line subwoofers, these are also capable of working with Class "D" amplifiers that place a lot of strain on the subwoofer coil. While most of the ordinary subwoofers cannot bear the extreme heat produced by Class "D" amplifiers, with the result that the coil gets damaged, power bass subwoofers are resilient enough to perform well despite the increased heat from Class "D" amplifiers.

Power bass subwoofers are more durable compared to conventional subwoofers available in the market. The company uses industrial glue to assemble the components together, and this makes the subwoofer capable of withstanding the high temperatures produced by the amplifier without coming apart as the glue melts. The subwoofers have been designed to incorporate vents for letting the warm air pass out of the system without overheating the device. This ensures that power bass subwoofers last longer than other subwoofers. The voice coils are anodized black, which helps to protect the system further from heating up. The subwoofer is couched in a custom-designed aluminum basket to maintain the sensitive components in a secure setting.

The cone of the subwoofer is made from non-pressed raw pulp which helps to break up the sound waves to create much louder output. The motion of the cone is further facilitated with the use of treated foam enclose that not only helps to keep the cone in place, but also increases the overall area of the cone so that louder sounds can be produced.

Power bass subwoofers also come with Pro-Lock terminals, which are specially designed to ensure that the speakers can cope with the large surges of power fed into them. Usually, all these power bass subwoofers come in three sizes, including 10, 12, and 15 inches. They can be used in enclosed spaces as well as in open areas.

Without a doubt, power bass subwoofers are designed to provide an experience that is the next best thing to hearing a live performance.

For that great sound experience that most music lovers long for, one has to be very careful when it comes to selection and eventual purchase of the sound system for personal use. A great number of sound systems have emerged in the market to meet the rising demand for audio reproduction but this does not mean that all these equipment are a good quality ones. For clear and quality music, the best sound system has to be in place.

Many people in this field will agree to the fact that you can enjoy music and have that memorable experience when the best external hardware is in place. In most cases surround speakers that are well linked and connected with woofers play a major role in ensuring that quality sound is produced. Regardless of all this, there are certain special considerations that people need to seriously look into in ensuring that they have the best sound system to suit their needs.

To begin with, one has to consider the size of his room or rather the room where the system will be placed. This is because the choice of the system will entirely depend on where it will be placed. For instance, big rooms require powerful systems so that the entire production of music is felt as it is to be. Small rooms on the other hand do well with satellite speakers that are usually meant to produce sound that is not ear breaking. If the room in question is the bedroom, you can go for directional speakers that will basically direct the music or sound to the room without casing discomfort.

Amplifiers can also be used but their use will all depend on the acoustic need at the moment. It is agreeable that amplifiers have a lower sound output than the speakers and therefore if a person does not want the sound that comes banging out of the speakers, then they would come in handy.

In making the quality of the sound more appealing to the ears, people have opted for the sub woofers as they give them just what they need at a given time. When the correct woofers are chosen, then one is assured of better sound that is of very high quality. As the lower frequencies deliver warmer sound, this component of a sound system is very important. The home theater system options usually come together with the sub-woofer.

Therefore, having said all that, it is important to pay close attention to a number of factors as they will determine the kind of sound system that they will get for their use. The most important factor is that of understanding the basics of the systems so that you get to know which one is suitable for your room size. You should also take into a consideration whether you need audio visual equipment or only sound equipment. Additionally, when you have an idea of the differences between the systems, then there is no doubt that you will end up with the best system.

Quality comes with a cost and therefore people need to note that if there is something they desire that is of high quality in audio reproduction there is a cost that they will have to incur. It is advisable that you get what actually suites your needs as well as your pocket. At the end of the day, you will have a sound system that best meets all your needs.

Most main speakers are typically passive. But most subwoofers include a power amplifier, creating the raw power needed to provide deep bass, without taking away any excessive amplifier power from the receiver. Subwoofers usually handle frequencies below 150 Hz or so.

Most subwoofer are designed to deliver accurate musical bass from a small enclosure. Small enough to be placed behind furniture or tuck into a corner and not be obvious from view. But its big bass output will be able to deliver all the visceral gut rumble for the action movies as well as tight, accurate bass precision for music.

The trend toward small, easily concealed main speakers has fueled an increase in the use of subwoofers. Compact main speakers, and in-wall or in-ceiling speakers, are often bass-shy. Large, costly floor-standing speakers often have plenty of bass, but they may be cosmetically unacceptable. Also, the speaker room placement that results in the best stereo imaging is almost never the best placement area for reproducing deep bass.

So don't make the front stage speakers do all the work. Instead, add a subwoofer to the system. This will free up the front stage to be more dynamic and expansive by letting the subwoofer take over the low frequency effects, the thrills of movies and the deep bass of soundtracks. The design of the intelligent amplifiers in subwoofers basically filters the low frequencies cleanly and smoothly, for better blending with the full audio spectrum being reproduced the main speakers. Easily accessible, professional-grade connections will give multiple options for hookup, so that one can tweak the performance according to the system needs. Adding a subwoofer, or two. will make TV watching into a wild ride, and music listening into a real live-on-stage experience.

It is also important to note that a subwoofer's deep bass is nondirectional. Therefor some care and planning is advised when considering where to place the subwoofer when installing the home theatre system.

By finding the best location for placing the subwoofer, it can make a dramatic difference in the sound. Corner placement is the de facto strategy for most people, possibly because the subwoofer will then be out of the way and almost always produces the most bass, but corner placement may not yield the most accurate bass, or smoothest transition to the speakers. The subwoofer and main speakers have to work together as a team, and ideally one should never hear the subwoofer as a separate sound source. All of the bass should appear to come from the main speakers.

With small speakers, it's best to keep the subwoofer within 1m or 1.5m of the front left or right speakers. Once the subwoofer is a lot farther away, it will be harder to maintain the illusion the bass is coming from the speakers. For really small speakers or skinny sound bars, keep the subwoofer as close as possible to the speaker(s).

For larger speakers (with 10cm or larger subwoofers), some placement experimentation may be useful. By playing music with lots of deep bass and keep repeating the sound as you move the subwoofer to all of the visually acceptable locations in the listening room provide the listener to gauge how different the bass sounds in different locations. Some location may give a muddy effect while other locations may give the effect that the sound is louder, and yet some other location will reduce the bass volume. The goal is to get the best balance of deep bass from the subwoofer and still have the mid and upper bass from the speakers in equal proportions (adjust the subwoofer volume control in each new position). In some rooms, smooth bass response won't be all that hard to achieve, but be prepared that there may be "problem" rooms where the bass always sounds boomy or muddy.
