BUILDING AN ENCLOSURE

5

If you’re planning to build your own enclosure and  are confused

 in what type of enclosure best suits your needs this page will help you 

choose what enclosure best fits your needs.  There are many different types 

of enclosures.  The two most common used enclosures are sealed and 

vented enclosure.  This page will show the advantages and disadvantages 

of the two enclosures.

Advantages of a sealed enclosures

*High power handing capability

*Great transient response

*Tolerant of minor enclosure size variation

*Easy to construct

*Smooth roll off (12dB/octave)

Disadvantages of a sealed enclosures

*Requires a woofer with a long excursion for better low bass 

  frequency response.

*Can have lower sensitivity than ported enclosures.

*When using high power and small enclosures, the woofer is not in   

  an ideal cooling environment.

*Lower bass as compared to a properly tuned vented enclosure 

above the ported tuning frequency.

Advantages of a vented enclosure

*Increased output around vented tuning

*Higher power handling above the port tuning frequency

*Extended frequency response

*Magnet is in a good cooling environment

*Handles higher bass frequencies with less distortion

Disadvantages of a vented enclosure

*Vented enclosure transient response is not as good as sealed 

  boxes because of the resonant effect of the vent tuning

*Midrange  sound  coming  from  inside  the  enclosure  through  the  vent             

  can produce unpleasant sound coloration.

*Loss of cone movement control below vent tuning, which can re

  sult  in high distortion and mechanical failure of the driver.

*Lower power handling below the port tuning frequency.
