Foam surrounds and ports will never give accurate response. It only
allows for a slower base response to go lower in a smaller box. To

fast as possible. Foam surrounds need a sealed box to do this. Good
bass reflex speakers count on a rigid surround and tuned port to
accomplish the same task.

Now that's a bold statement.

Thankfully, another poster has addressed it for the rest of us.
