What is bass reflex design?

What is the difference between bass reflex and acoustic suspension?
“Bass reflex speakers have tuned ports, where acoustic suspension speakers are sealed. Bass reflex speakers have port noise and less accurate cone control because there is no sealed air cushion that acts as a spring behind the woofer cone to keep it moving accurately in tune with the signal.

Why are most speakers ported?

What is the hole in the back of speakers for?
Speakers have holes to allow the lower frequencies that often get trapped in the back to be enhanced. When your speaker is working, the vibrations inside compress air in the front and back, which can become unbalanced. Bass reflex systems have these holes, so the bass sounds are not lost.
What is 3 way bass reflex speaker system?
