The S 14 C has four drivers with a diameter of 110 mm. Two of them are used as pure woofers, the other two as mid-bass drivers. The tweeter range is also taken over here by the fabric dome with its 28 mm. Due to the sophisticated equipment, the housing of the S 14 C could be very flat with a height of just 15 cm and therefore fits perfectly under almost any screen. The width of 70 cm and the depth of 19 cm, on the other hand, leave enough space for the installed drivers to develop properly. The result is a frequency response with a lower cutoff frequency of 38Hz.HF Driver Type: Dome TweeterMiddle Speaker: 4,5"Housing: MDFWoofer: 4,5"Impedance: 8 OhmMade in: ChinaPackage Quantity (pcs): 1Package Contents: ManualPower RMS: 100 WOriginal Colour by Producer: BlackPower: 200 WSet Content: 1 pcTweeter: 1"Bandwidth: 2,5 BandwidthSensitivity: 90 dBype: Center SpeakerColour: BlackSystem: PassiveBass Reflex Port: YesWidth (cm): 70.0Sensitivity (dB): 90.0Crossover Frequency: 2700 Hz;500 HzImpedance (Ohm): 8.0Net Weight (kg): 7.0Frequency Range: 38 Hz - 38 kHzDepth (cm): 19.0Height (cm): 15.0Power (Watt): 200.0.
