Enclosure

• A well designed enclosure--or box--contains acoustically absorptive material to eliminate any sounds or vibrations created by the enclosure.
  
  

Electronic Crossover

• Quality speakers contain electronics that send only a specific portion of the audio spectrum to specialized speaker components designed to reproduce low, middle or high sound frequencies.
  
  

Specialized Speakers

• Used in conjunction with an electronic crossover, sound is more accurately reproduced using different speakers for different parts of the audio spectrum. For example, high quality speakers use a woofer for the bass frequencies, a midrange speaker and a component called a tweeter for the highest frequencies.
  
  

Component Construction

• The design of the individual speaker components and quality of materials used in their construction can enhance how they reproduce audio signals.
  
  

Power Capacity

• Speakers must be able to play audio at the original recorded volume without distorting the audio signal. If the amplifier delivers more power than the speaker was designed for, distortion occurs.
