I remember the slotted port being on the back at the bottom. There are Internet pics showing this but apparently photos can be altered. The it's sealed' folks must be correct. Having owned one doesn't seem to matter.
Powerfield 1500 sub, sealed.
Powerfield 15TL sub, Slotted port.
TL = Transmission Line.
