I have one of those Exacts from PE. It's a VERY good sounding sub. It's almost too "dry" in that it has no artifacts. It basically doesn't have the balls for the car environment, so I'm building a box for the living room for mine.
BTW, that basket has/is used by nearly every subwoofer manufacturer known at one point or another. The FIRST time I can remember seeing it was on the SoundStream SS subs in like 1990-ish. I think MTX used it around then, too.
