User manual of Rockford Fosgate P3SD4-12 .

RECOMMENDED ENCLOSURES This manual outlines two specific types of enclosures that provide distinctly diferent performance. Ths section is to help you decide which type is best for your application.


Sealed enclosures are the simplest to build. The most important part of building a sealed enclosure is to make sure that the enclosure is airtight.

Using glue and some type of sealant on all seams will ensure sold construction and prevent air leaks. The box volume will directly impact the performance of the speaker. Larger enclosures will provide flatter response and deeper bass where smaller boxes will provide a bump in the response curve and generally higher output for greater SPL.

Advantages of sealed enclosures:

+ Small enclosures

+ Linear (Flat) response

+ No port noise

+ High power handling at all frequencies

+ Excellent for sound quality

+ Extended low frequency output when compared to vented enclosures

VENTED ENCLOSURES Vented enclosures vary only from the sealed enclosure in that a vent or port is added to “tune” the enclosure. The enclosures recommended are designed for great overall performance. Larger boxes tend to be easy to tune to lower frequencies while medium and small boxes are easier to tune to higher frequencies. The vented design is less linear in response than the sealed box but with noticeably more output at the tuning frequency.

Advantages of vented enclosures:

Higher average output than sealed “Tuning frequency can be easily adjusted by changing port length

Deep bass response with lower power requirements

Great for high output with limited power

The graph shown here is a sample of how the F3 drop-off point differs between sealed and vented enclosures.
