- I have a Paradigm 7SEII and it is ported on the rear with two small bass ports.
- Both ports are vents from one enclosure. I don't have any very source material
- with very low bass but I can't hear any audible wind noise at normal listening
- levels.
-
- Should I remove the two ports and replace them with one single one? :)
