Subwoofer Speakers

If you are amongst those who really enjoy the music and do not like to compromise on the quality, subwoofer speakers are a must for you then. The job of a subwoofer, or subs as many call them, is to reproduce bass audio frequency. Depending on the type and cost of the subwoofer you go in for, these subs can reproduce a large range of frequencies, from as high as 150 Hz to as low as 20 Hz, with special ones going even lower than that.

Subwoofer speakers are used to enhance the performance of the main speakers on low frequencies. There are both passive and active subwoofers, with the main difference being that active subwoofers will have an amplifier built-in while passive subwoofers must have an external amplifier attached. A subwoofer is made by attaching woofers into a casing, usually made of either plastic or wood. They can be designed in a number of different styles, depending on what results are expected. Each design will have an impact on things like size and cost, of course, but also on end results such as distortion rate.

Ever since they came into use in the 1960s, subwoofers have been extensively used for a variety of purposes. From sound recordings, to live concerts and even great Hollywood movies, all have used subwoofers to provide the right kind of sound. A fine example is of the Hollywood movie Earthquake which used huge subwoofers to produce very low frequency sounds that were so effective in providing one of the best cinematic experiences ever. Today, from night clubs to home theaters, from car stereos to PA systems, subwoofers have become an integral part of all kinds of sound related set ups.

Understanding the working of subwoofers a little better, let us analyze the basic structure of it. Subwoofers actually use speaker drivers with diameters usually varying from 8” to 21” in order to faithfully reproduce the long low frequency waves that the human ear can not only hear, but also enjoy listening to. The diameter of the subwoofer driver depends on the following factors:- design of the speaker, lowest frequency that it is required to reproduce, sound pressure level and distortion permitted.

Leading subwoofer speaker manufacturing companies includes stalwarts like JBL, Bose, Sony, JVC, Altec Lansing, Yamaha, Bazooka etc. The list goes on and on. There are over two hundred and sixty big and small companies in the US alone that produce subwoofers for home and professional use.

However, if you are planning on buying a set of subwoofers, do not go for the name of the company only. There are certain parameters that need to be kept in mind before you go subwoofer shopping. The two main considerations are:

a) Power – Depending on the size of the room, choose the subwoofer that requires the right amount of power and has the right amount of amplifier. A disproportion in the size of the two would spoil your entire experience.

b) Firing – Subwoofers are of two types, down firing and front firing. Neither of them is better than the other, and the choice totally depends on the design and the kind of usage.

With today’s home theater systems, as well as the advanced multimedia capabilities of current computers, subwoofer speakers are a more important component of the experience than many think. Too many people focus on the picture quality of the video components and forget to pay attention to the sound quality of the audio components. For a true home theater experience, you must have quality subwoofer speakers installed in order to enjoy all the richness of the lower bass tones in your music or other media.
