Circle 3; Key Features (Passive And Active); Key Features (Active) - HHB CIRCLE SERIES Operating Instructions Manual

Circle 3

The compact size of the HHB Circle 3 studio monitor is ideal
when space is at a premium. Equally at home in project or
commercial studios, the Circle 3 features a 4.5" paper pulp
cone, optimised for use in the smaller cabinet. An anti
magnet screen allows the Circle 3 to be placed next to
computer or video monitors. The Circle 3 monitors can be
used as part of a surround sound system since, passive or
active, they produce a sound which is both clear and
dynamic - the HHB house sound.
