Subject:Re: 12 speaker in custom cab?

Bruce, i notice that you have vents in the backpanel, but no porthole
next to the speaker.
What makes vents different from ports?

If i were to make vents in my backpanel, does it matter where they
are, or should it be placed as close to the motor as possible just for
cooling? How big should it be?
