Sound System Design Portfolio (pg8)

Research:What design is best for a speaker box?

Sealed speaker box enclosure                                                          sealed

Sealed enclosureAdvantages:
*easy to make
*force generated by the air pressure keeps the driver exactly where it’s supposed to be.
*sound that’s produced is tighter and more precise
*improves bass
*can be used in different installations.

Disadvantages:

*amplifier must constantly increase the electrical signal in order to handle the air pressure.



Bandpass enclosure                                                                       bandpass
Bandpass enclosureAdvantages:
*high efficienccy
*provides good bass
*used for increasing gain in bands of frequencies
*increased power handling in the band

Disadvantages:

*large enclosures are hard to design and build
*errors in construction process of making this enclosure
are likely to happen.

Ported enclosure                                                         

Advantages:
*high bass out out                                                                                                           ported
Ported enclosure*less amplifier power needed
*high frequency
*low distortion

Disadvantages:

*larger than sealed boxes
*errors are likely to happen when making this enclosure.
*complex
