Home Cinema Speakers

If you ever speak to twenty different home cinema specialists you'll most likely

get twenty different answers as to which is actually better, active or passive design. Active home cinema loudspeakers have the audio amplification included in the unit so they are generally heavier in design and will require a primary power connection in addition to the audio cable. On the other hand, passive home theater loudspeakers need an external audio amplifier to make them do the job and so they only have a sound cable connection and do not require any local power.

With out really getting too techie, when the sound is sent it may be transmitted in a variety of distinct methods and some are actually much better at keeping sound quality while some others may be less vulnerable to disturbance and usually you'll find it's a trade off between the two. For instance, active home theater sound systems need a sound line level wire to make them do the job. Now line level transmission may be vulnerable to disturbance if it is run alongside primary wires for example. This may cause a low sound on top of whatever audio is being released of the speakers that may be really frustrating and degrades the quality of the home theater. Passive home cinema loudspeakers on the other hand require a loudspeaker level wire to make them work and are less prone to disturbance. The actual trade off is that the line level transmission maintains a much better sound quality than speaker level and so if the wires are running over an extended distance, say more than ten metres then you'll get a lower quality audio reproduction.

To go a little further you may also consider digital or analogue home theater loudspeakers which both function on line level transmission however one is digital and the other is analogue so let's focus on the difference. Digital transmission transmits all the audio signals in zeros and ones whereas analogue sends the signals in waves. Basically you will find that digital loudspeakers will probably be less prone to disturbance but will lose some of the audio quality as they need to round every thing to either a zero or a one.

Home cinema loudspeakers are made up of various audio drivers that are basically just cone shaped parts of paper which push air away from the loudspeaker. They're different sizes based on the type of audio to be reproduced and generate the sound for your home theater. In essence there are only three different kinds of drivers and every one deals with a different audio wave length or to become less technical, a distinct audio pitch. One of them deals with the high end, referred to as the tweeter, one deals with the middle range, the mid range, and finally the third one deals with the low end, the woofer. You will need to look for a loudspeaker that has at least one of these drivers and even preferably two or even more to obtain the finest audio reproduction.

Now there are lots of other considerations which will need to be factored in when deciding on home theater speakers like the quality of the sound cable utilized to link them as well as the build quality of the speakers themselves as you of course want to minimize inner resonance that can have an effect on sound quality.
