Speakers

Speakers come in a vast majority of sizes and shapes such as, surround speakers, computer speakers, floor speakers, subwoofers, etc. and can make choosing the right one for the task difficult.

When choosing the right speakers for the task the first thing you must determine is placement - where will the speakers be located? Based on location, you have different types of speakers available:

- Floor-Standing Speakers

Floor-standing, or tower, speakers have been around for years and in many ways

remain the standard against which all other speaker types are judged. In general,

they are larger than other types of speakers, reproduce a wide range of

frequencies, including deep bass, and are usually more efficient, giving you

more volume per watt of amplifier power.

Floor-standing speakers tend to be more expensive than other smaller

speakers, but they're hard to beat for big, room-filling sound. They're great if

you've got a larger room, or if you plan to do a lot of stereo music listening.

integrate them into a larger system, or read about speaker placement for stereo

music for helpful tips on positioning to get the best sound in a two-speaker

setup.

- Bookshelf Speakers

If you're working with limited space (or budget), bookshelf speakers are a

good alternative to floor-standing models. With bookshelf speakers, you get a

smaller cabinet that'll fit on a stand or on a shelf, and excellent performance in a

smaller box (and usually with a smaller price tag too).

 

- Surround Speakers

Floor-standing, or tower, speakers have been around for years and in many ways

remain the standard against which all other speaker types are judged. In general,

they are larger than other types of speakers, reproduce a wide range of frequencies,

including deep bass, and are usually more efficient, giving you more volume per watt

of amplifier power.

 

- Computer Speakers

Computer speakers can range anywhere from basic, small-powered 2.0 systems for

simple office work or full, surround sound 7.1 systems, depending on the need of your

tasks and projects.

 

-  2.0 systems (2 speakers) are typical of basic office setups where audio is

only necessary for basic computer work and basic audio playback.

 

2.1 systems (2 speakers, 1 subwoofer) are typical of basic office setups

where additional audio clarity and body is necessary (music playback,

mutimedia viewing, etc.).

 

- 5.1 systems (5 speakers, 1 subwoofer) are entry level setups for surround

sound systems where multimedia viewing is important and multiple channels

of audio playback are necessary.

 

- 7.1 systems (7 speakers, 1 subwoofer) are advanced level setups for

surround sound systems where the maximum number of surround channels

are required.

 

Based on which category above matches fits your tasks, you will then need to look at certain specifications for each system.

- Dynamic Range

The difference between loud and soft sounds. A speaker with wide dynamic

range — one that can reproduce the sudden and wide changes between loud

and soft sounds in music and video soundtracks — will sound more realistic (all

other things being equal).

- Frequency Response

The human ear responds to frequencies from approximately 20 to 20,000 cycles-

per-second, or Hertz. A speaker's frequency response indicates how much of

that range can be reproduced.

- Impedance

The load value (in ohms) that the speakers present to the amplifier — the

amount of resistance to the flow of current. While playing music, a speaker's

actual impedance constantly fluctuates; however, speakers are usually given a

single nominal impedance rating for easy comparison. Low-impedance speakers

(4 ohms or less) can cause problems with receivers or amplifiers that are not

designed to deliver large amounts of current.

- Sensitivity

A sensitivity rating tells you how effectively a speaker converts power (watts)

into volume (decibels). The higher the rating, the louder your speakers will play

with a given amount of amplifier power. Sensitivity is often measured by driving

a speaker with one watt and measuring the loudness in decibels at one meter
