Sure, if you look at them from the front the FR6 look like fairly ordinary, two-driver bookshelf loudspeakers, with a single mid/bass driver and a dome tweeter. But if you look around the back of the cabinet, you will find an enormous 'race-track'–shaped passive radiator. “So what?”, we hear some readers scoffing, “passive radiators aren't that unusual!”
Ignoring for the moment that passive radiators are actually fairly unusual on cabinets of the FR6's size (38.5 × 23 × 33cm, if you were wondering), there is an additional driver inside the FR6 cabinet, mounted on an angled internal baffle, so that each FR6 in fact has two mid/bass drivers, a tweeter and a passive radiator. Tell me that isn't unusual…
