Subs are getting to be much more important to your own home theater experience. When you go to the local cinema theatre, you marvel not only at the images projected on the screen, but the sounds emanating near you. What really grabs you, though, is the sound most people feel; the deep bass that shakes you up and gets you right in the gut. A complex speaker, known as the bass speaker, is mainly responsible for this experience. The bass speaker is made simply to reproduce the lowest of audible frequencies.
Passive Subwoofers Passive subwoofers are powered by an outside amplifier, within the same fashion as other types of speakers in your system. The strong but subtle consideration here is that since extreme bass needs more electricity to reproduce low frequency sounds, your amplifier or receiver should be effective at output enough power to uphold bass effects in the subwoofer without depleting the amp. The amount of power is determined by what's needed from the speaker and the size of the space (and exactly how much bass you are able to stomach!).
Powered Subwoofers In order to resolve the circumstance of inadequate power or other characteristics that might be lacking in a receiver or amplifier, powered sub woofers are self contained speaker/amplifier units while the characteristics of the amplifier and sub woofer are optimally harmonized. As being a side benefit, all a powered subwoofer needs is known as a line output from a receiver. This arrangement needs a lot of the power load away from the amp/receiver and allows for the amp/receiver to power the mid-range and tweeters with less effort.
Front-Firing and Down-Firing Sub Woofers Front-firing sub woofers contain a speaker mounted so that it radiates the audio from the side or front of the bass speaker enclosure. Down firing sub woofers utilize a speaker which is mounted so that it radiates downward, towards the floor.
Ports and Passive Radiators Some bass speaker enclosures utilize an additional port, which pushes out more air, improving bass response from a more efficient manner than closed enclosures. Yet another kind of enclosure runs on the Passive Radiator in addition to the speaker, instead of a port, to help improve preciseness and efficiency. Passive radiators either can be speakers having the voice coil removed, or else a flat diaphragm.
Crossovers The crossover is often an electronic circuit that tracks all frequencies below a specific point to the bass speaker; all frequencies above that point are duplicated to the main, centre, and surrounding speakers. Typically, a good subwoofer incorporates a "cross-over" frequency close to 100hz. Gone is the requirement for those large 3-Way speaker systems with 12" or 15" woofers. Smaller satellite speakers, optimized for mid-to-high frequencies, that occupy significantly less space and therefore are now common in numerous home theater systems.
Deep Bass is Non Directional In addition to that, while the deep bass frequencies reproduced by way of the sub woofers are non-directional (as frequencies that are at or below the threshold of hearing). It's very hard for our ears to actually pin-point the direction in which the sound is originating from. That's the reason we are able to only sense that an earthquake seems to be all around us, rather from from a particular direction.
Sub woofer Placement Caused by the non-directional sound that's reproduced by way of the subwoofer, it could be placed any where in your theater room. However, the best possible results depend upon room size, furnishings, wall construction and floor type. Typically, best placement for a sub woofer is by the front of your room, simply to the right or left of the main speakers, or even in a front corner of your room.
In Conclusion Despite the many technical features and design components of subwoofers, the type of bass speaker you ultimately choose for your personal system relies on the characteristics of your room and your own preferences.
