Home theater speakers receive audio signals and convert them into sound. There are usually several speakers in a home theater, each one handling a different frequency and placed in a specific part of the room to create a fuller sound. They are wired to various media devices, such as CD and DVD players, mp3 players, VCRs, and computers. Newer speakers use wireless connections such as radio, infrared, and Bluetooth to eliminate clutter.
Kinds of Home Theater Speakers include the following:
Front, left, and right speakers
These speakers are designed to blend in with video to produce more realistic sound.
The front speakers produce most of the special effects in DVD movies and reproduce off-screen effects.
The left and right speakers also serve as stereo speakers for playing music. They are placed on either side of the TV.
They are available in floor-standing, satellite, and bookshelf-size models.
Center channel speakers
Center channel speakers keep the sound synchronized with the video.
They also handle most of the soundtrack and dialogue in movies.
They are usually placed on or below the TV set.
Surround speakers
Surround speakers deliver ambient and directional sounds, such as footsteps, rain drops, and passing cars.
They are placed at different corners so that the sound seems to “surround” the room.
They are available as desktop, shelf-mounted, or in-wall speakers.5.1-channel systems use only one pair of surround speakers, while 6.1 to 7.1 systems have extra speakers used as back surrounds.
Powered subwoofers
Powered subwoofers produce bass and low-frequency sounds to give a fuller feel to the soundtrack.
They also enhance strong special effects such as explosions, thunder, and collisions.
They can be placed anywhere in the room because the bass sounds are omni-directional.
Voice matching: Make sure that all your speakers have the same timbre and tonal quality for a more seamless and realistic sound. Look for a pre-matched speaker system or buy all your speakers from the same manufacturer.
Video shielding: This is a lining or cover that keeps the magnetic energy inside the speaker case. Choose a video-shielded speaker to prevent interference with other nearby devices. This is especially important with center channel speakers, because they sit close to the TV and they can distort the picture if not properly shielded.
