Loudspeaker types
There are four speakers home theater basics: towers, satellites, subwoofers and center channels. A
tower speaker is a large independent model, capable of reproducing a wide range of sound. The
satellites, which can be used both as front or rear channels (surround sound) are small, low-limited
models designed to be paired with a subwoofer - a dedicated speaker for bass reproducing the
surround channels and low frequency Dolby Digital and DTS. And a central channel is horizontally
oriented satellite is designed to reproduce the dialogue.
o Free-standing against the wall
In the past, home theater speakers are typically installed along with the big-screen TVs - either alone
or placed on speaker stands. However, many new models on the wall of drawings that come with
wall mounting equipment. One advantage of this type of speaker is placed on walls do not take all
the space in the room. A second advantage is a slim design, embracing the entire wall of flat screen
plasma and LCD televisions.
Do you really need a center channel?
In some systems - specifically built around a large, thin rear projection TV - find a place to put the
center speaker can be a problem. Even if you can do without one, it is not recommended - center
channel speaker is designed to reproduce the sounds. You will notice that the film dialog sounds a
lot clearer when you use them. So rather than ignore the center speaker or using the TV built-in
speakers, such as replacing the center channel (a terrible choice, because the tonal balance of the
TV speakers is not able to meet that other speakers), look for alternative installation. Speaker wall
mounts do a great option, especially flat-screen TV. Most of the TV is on the shelves of storage that
can accommodate a small center speaker.
Connecting the speakers. A variety of connectors can be found in the back of the speakers.
A spring clip connector is a plastic spring which is usually in the back of the speakers cheap. The
connection provided by spring is not as safe as other types, and can accept bare speaker wire.
Terminals are step-up connection option
can be found in high-quality speakers.
There are two types of screw terminals:
one normal and one in five directions.
Regulate both types of banana and spade-
lug connectors for speaker cables. Contact
they offer is very safe, and in some cases,
the connector is gold plated to prevent
oxidation - a condition that can potentially
affect performance. And five terminals that

In-wall and ceiling speakers in the + and -
For those who prefer to keep their audio / video equipment out of sight in the walls and ceiling
speakers are an excellent alternative to home theater systems conventional models. Although the
sound quality of the wall and in-ceiling models are generally a notch below that of conventional
speakers can be mounted inside the cavity recess in walls or ceiling of your room, they not take any
space. Both are also designed to contain vibrations in the cabinet so you do not have to worry about
knocking the walls of action movies. Installation in walls and ceiling speakers is to run the son
through the walls and / or ceiling of your home. If you are an experienced do-it-yourself type, you
can be at this task, but for most people, it is best left to a custom installation.
Issues surround speaker: the direct-radiating, dipolar and bipolar are several options to consider
when choosing a surround system.
Direct Sound fire burst models directly from the front baffle of the speaker to the ears of the
listener. It is a good all-purpose selection of surround sound because their clear, focused dispersion
pattern can accurately convey the directional pans in DVD soundtracks.
Dipolar models radiate sound both behind and in front of the speaker, the other party to set the
drivers wired out of phase with each other. This structure provides a more diffuse, spacious sound of
a direct radiating design, while maintaining focus on some of the latest release. (Dipole models are
favored by THX-certified designs precisely because of their diffuse sound, which is more like what
you want to listen to the real cinema.)
Bipolar models also sounds radiate from the front and back, except that in this case, two sets of
drivers are wired in phase with each other. This design allows a bipolar speaker to provide the best
of both worlds: a direct radiator is the clarity and focus, and a dipole space.
o What is the frequency response, and what I look for?
The range of audio frequencies that can reproduce a speaker is known as its frequency response.
The human hearing extends from 20 Hz to 20 kHz (20,000 Hz) - a period of several models that are
able to fully cover. Low frequencies are in the lower range (20 to 120 Hz) is the most difficult for a
speaker to cover. The satellites do not try at all, but the task is for a subwoofer - a bass drivers with
dedicated enough to spend the huge amount of air needed to reproduce low frequencies. From the
tower of speakers usually contain one or more low, they generally provide a decent bass. But if
you're looking for tower speakers - especially if you plan to use in a system where there is no
subwoofer - will have to check the bottom of its frequency response specification. And remember
that not all measurements are the same.
For example, the bass response of a loudspeaker spec'd -6 dB at 40 Hz probably will not sound as
full as it measures -3 dB at 40 Hz
o President and selection
Most new speakers are designed to be compatible with a wide range of audio amplifiers and
receivers, so information such as an impedance meter for resistance of the speaker of electricity
flowing through it, usually defined in ohms are not things that you need to worry much. But what

3. you should know that the amplifier has to work harder to drive the impedance of a lower rating with
a higher rating. To say that the receiver is rated to produce 100 watts into 8 ohms. If your speakers
are 8 ohm spec, then you probably have no problems. But if the speaker system set to 4 ohms or
less, the possibility that the same receiver to overheat and shut down grow.
o Implementation: The Final Frontier
Many people tend to be informal about where to place your speakers more often than not, put it in a
place where the ancients, it is convenient. But speaker placement becomes crucial when creating a
home theater system. You want the placement of surround effects in your room to match what is
happening on the screen, and this will only happen if the speakers are configured correctly.
Torres models versus satellite channel or in the stands should ideally be placed equidistant from the
sides of the TV and about three feet from the front wall. This setting will accentuate the images and
sound effects to reduce the room construction problems. And the box should be pushed into a corner
of the room to the sound effect of strengthening the walls adjacent to reinforce the bass. Although
the investment guidelines for the surround speakers are less stringent than those of the speakers,
installing them in a high position on the sides and slightly behind the listening area usually to
improve the surround surround.
