Who makes an active speaker that isn't ported?

I'm trying to think of a 3-way active speaker that isn't ported and coming up with a blank. If someone does such a speaker, we could be looking at sonic nirvana.

Cheers,
DB

So they are ported but not to extend bass frequencies.

Do you know anything about this? If so, care to expand? Cheers" Well, I'm repeating what i've been told, the cabinets are designed in such a way that they maintain a particular impedance, the holes on the cabinet are the visible mechanism from which the air is released, but there is a matrix which leads to a cavity that is then ported. Any sound coming from the port is unintentional. You will not feel air chuffing out of the ports due to bass and measuring the speakers you will see that they have a 2nd order rolloff not a 4th order like a ported system. In both cases Meyersound and ATC, neither are in a huge hurry to talk much about the cabinet design internally.
