The larger version with 4" speakers has two horns openings at the top and bottom of the rear of the cabs. Suitable for the room 12 to 30 m2. The smaller F85 with one horn's opening on the rear bottom can be used as a bookshelf as well as a floorstanding speaker. They can be used alone for rooms from 9 to 20 m2 or as surround satellites installed behind the listening position in addition to the F105.
