Someone reached out and said they would like to part with these, thought they were 5.5's but these have a single port on the bottom. Owner says the tags are missing and he doesn't know the model, hope someone can help.

the Kg 5.2 is also a vented design but rather than a reflex vent they use a passive radiator which amounts to the same difference six of one a half dozen of the other.
