The Ultra-compact Gold C150 centre speaker is small enough to fit into most AV racks and is designed to match the smaller Gold speakers in a more bijou home theatre configuration. However, because it shares tonal characteristics with all models, its capabilities are also compatible with any 'Gold' system design. The Gold C150's lustrous sealed cabinet is home to twin 5.5" drivers and the ribbon in a two way orientation, providing superior dispersion across a range from 50Hz to 60kHz.
