A Review By: Alphonso Soosay
|Before you take advantage of your speaker’s choice, try to imagine where you are going to position them in your room. Speakers can be positioned on floor stands, suspend on wall brackets, or positioned on furniture cabinet. Subwoofers typically sound best on the floor, in room corners or near the left- or right-front speakers. The front three left front, centre front, and right front speaker’s usually sound best when positioned with their tweeters elevated to the same height as a seated listener’s Ears. Whatever the situation may be in your home, try to keep the centre speaker near the same height as the left and right speakers. You can place speakers on shelves or on, in a low cabinet or entertainment centre. Several type of speakers are better suited to this arrangement than others. “Acoustic suspension” sealed satellites are the most appropriate. Subsequently with ported speakers it can be ports located on the front or the back of the speaker cabinet. However, speakers with rear mounted ports will not perform at their peak when they are placed inside a piece of entertainment cabinet. As for the rear channel surround speakers, they usually sound best when positioned two, three or more feet higher than the front speakers. However, high fidelity Super Audio CD and DVD Audio music will sound best when surround speakers are placed at the same height (Ear level) as the front speakers. That’s from practical experienceChoice of quality speaker’s available right now on specials is: B&W, FOCAL, PSB, JBL, ENERGY, NORH and AXIOM Speakers. Check with your nearest Home Theatre Consultant.
HOME THEATER SPEAKERS AND STEREO SPEAKERS: Front speakers perform best when the listener’s EAR is directly in front of the speaker and at the same height as the speaker drivers. The Audio response where the driver is pointing directly at the listener is called the on-axis response. As soon as you move off-axis, the speakers will not sound as loud. That’s the difference. Generally, Stereo speakers have a better off-axis response than Home Theater speakers. The sound that the listener hears is a mixture of the left and right channels, combined with the reflections of the both channels off the walls, floor, and ceiling. Stereo speakers sound best when the listening area is centred and in front of the two speakers, but they also sound good from either side of the room. With a well recorded CD soundtrack, both the left and right signals comprise the same music, but they will not be at the exact same volume levels because of the different musical instruments mixed at different levels in the left and right speakers. If you are directly in front of one of the speakers, you should still be able to hear some parts of the musical instruments coming from the other speaker.
REAR SPEAKERS: Rear speakers in a Home Theater system have a greater diffusion than you would get with stereo speakers. Sometimes, rear speakers have drivers firing in multiple directions. This causes a lot of reflection against the walls and makes the rear echoes sound like they are coming from a spacious area.
CENTRE SPEAKER: Center speaker is the most important speaker in a Home Theater system. It produces all of the quality voices that come from actors on the screen. Without a centre speaker, the voices would be coming from the corners of your room. Selected Home Theater speaker systems use two centre channels instead of one. It is debatable on whether more than one centre channel is necessary. It probably depends mostly on the size of your TV viewing and the distance you are seated.
THE SUBWOOFER: In the past, the word subwoofer assumed that a speaker is to produce sounds deeper than a regular woofer. A subwoofer driver then would have to be at minimum a 12″ wide to produce these frequencies. Now, the term has come to suggest that it is the largest driver in a system, regardless of whether the system has a woofer or not. In some small speaker systems, especially computer multimedia systems, a subwoofer can be 6″ or smaller. A subwoofer of this type is completely ineffective in a good Home Theater system.
