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
- 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
- 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.
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.
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
