Although most people that watch television appear happy with the inbuilt sound systems there is much to be said for a television that is linked to it’s own dedicated sound system. If you will only be watching soaps on it you may not care so much, but anyone that watches films, DVD’s, blu-ray and even gamers should consider it as an option. Although many TV’s have a good speaker on them, there is nothing like a full surround sound system. The main reason to opt for a HD television set is not just its massive publicity but being influenced by sets viewed at a friend or relative’s home.

Before rushing out and buying a new HD Television, you should consider carefully what you want from it, and what your budget is. In case you already own surround sound speakers or thinking of buying them, remember 10 percent of the total TV cost would be spent on cabling the speakers. The external speakers ought to be controlled with the help of amplifiers or av receivers. This is also an extra cost from several hundred upwards into the thousands but warrants another article altogether.

Several aspects govern the world of speakers and there are several types available – you are considering the ratio of 5:1 and above which are 5 speakers to one sub-woofer. The speakers consist of one centre speaker, a left and right “surround” speaker - these typically sit at the far, front corners from the seat and a left and right rear speaker. Each is independent and although the positions done have to be equal the optimum seating place is in the middle of them all. You can configure the av receivers and amplifiers to optimize the volume output and place the speaker accordingly.

The basic function of a sub-woofer is to give the movie sound a real-life feel so having one would improve your overall movie viewing experience. It can lend life to sound and we all know this when we watch movies in cinema halls. Besides the deep bass frequencies which the sub woofers emit have a surrounding effect since they are at par or below the level of human hearing. It is impossible to detect from which direction the sound is coming, so the sound of an earthquake feels as if it is happening all around us.

The subwoofer can be placed anywhere in the room, however, optimum results depend on room size, floor type, furnishings, and wall construction. Usually the perfect placement of the sub woofer is in the front portion of the room, to the right of left of the main speakers. Oftentimes it is easier and less expensive to have speakers that have been previously owned. An excellent starter choice for speakers, if its within budget is the Canton movie CD-1 (now CD-101) which has a high quality, slimline aluminium construction that makes it a real eye-catcher.
