Wharfedale Pro SI-18B

The SI-18B is a very compact sub-bass system designed for use in combination with the SI-28, SI-12 and SI-15 full range loudspeaker systems in applications where extended low frequency output and increased system headroom are required. This powerful bass system is capable of delivering high sound pressure levels with very low distortion over sustained periods. Superior output in extreme conditions is maintained through the use of effective heat dissipation mechanisms avoiding loss of power compression found in other systems.
