porting

[smopo24]

i've seen ported cabs before, but wondered what is porting exactly? what does it do to the sound?

Ports allow the bass frequencies that come from the back of the speaker a place to escape into the outside atmosphere. The ports are often place so that certain frequencies will come out in phase with the ones that are coming out in front, creating a hyped up bass effect. Since the frequency range of speakers is usually so small and very inefficient at low frequencies ports often are what makes bass possible on smaller speakers.

One of our cats sometimes jams her head into the ports on my Events. I don't know what's wrong with her, but she's funny.

thanks for the explination; i figured that this 2x12 cab i have just purchased would have enough bass response on it's own.....but it's good to know that the porting will help.
