I have a 15" Rockford Fosgate DVC sub in a ported enclosure and am thinking about getting a sealed enclosure to save on space. I know the obvious drawbacks and benefits of a sealed enclosure (loss of lower freq, etc.) but I've heard that sealed enclosures are harsher on speakers. Is that right?

 

Well, I guess you could say that is sort of true. A ported box is vented, so the cone and suspension is subjected to a slightly lower pressure. Also, the voice coil is cooled a bit better then when in a sealed box. If the sub is designed for sealed, and you don't go over the recommended power levels too much, you should have a happy sub.

 

the only real drawback to a sealed box is the loss of frequency range. Fosgate subs can handle a lot of abuse, so heat should not be a factor.

 

you also need more power. But it is a clearer bass

 

Sealed subs aren't as loud and depending on your tastes, the bass may be too tight for the music you listen to.

 

Ported and bandpass fit rap music really well and thats pretty much it. A sealed enclosure will make everything sound good just rap would be as boomy.

 

ported vented enclosers play 3db higher!
