Speakers And Subwoofers: High And Low Frequency Sound Outputs Sub Woofer Tip! For SPL systems: Because subwoofers are loud, they are the preferred speaker to make a whole lotta noise. A good sound system would depend to a great deal for on the quality of the speakers and subwoofers to output the sound produced from the other components of the music system. Besides the speakers themselves, the subwoofers are individual speakers that are used with the sole intention of reproducing low-frequency sounds. The subwoofer may not be the fanciest component of a home theater system but it nevertheless is vital in reproducing a decent listening experience. Get The Complete Audio Frequency Range Speakers and subwoofers provide the complete range of frequencies that are audible to the human ear and may range between twenty to twenty thousand hertz. The purpose of adding the subwoofer to the audio sound system is to output the lowest end of the frequency range and with the help of a low-pass crossover one can filter out sounds that are higher than a given frequency and in addition, one may note that the crossover point is user-adjustable. Speakers and subwoofers complement one another and since low frequency sound waves are of greater length they require large drivers as well as consume lots of power and the difficult job of reproducing those low frequencies falls squarely on the subwoofer, which is why one gets to hear those deep bass sounds, using a subwoofer. So, when shopping for a combination of speakers and subwoofers one would need to assess as to how much power is required and for serious bass one should settle for a speaker and subwoofer system that allows for more watts in the built-in amplifier. A twelve inch subwoofer would also be desirable for getting deeper bass sounds. A home theater that has a floor standing speakers and subwoofers combination would provide extra good bass response and output the full sound and the subwoofer would be instrumental in giving an extra dose of deep bass. The same cannot be said of bookshelf speakers as they are not able to produce low frequency sounds and a subwoofer added to the speaker system would become useful for producing lower frequency sounds. One may be pleasantly surprised to know that a pair of small speakers and subwoofers would be able to sound as good as a pair of large speakers. All that may be required is to tweak the crossover and even a bookshelf speakers and subwoofers combination would deliver impressive sound without taking up too much space. Other aspects that need to be considered for a speaker and subwoofer combination would be whether to go in for a two way or three way speaker.
