No speaker lineup would be complete without a well-engineered shelf speaker. Like the floor-standing models, just 21.5 cm wide and with a height of a good 35 cm, the S 30 really does fit anywhere. It is the ideal speaker for entry into ambitious stereo and can be used perfectly as a surround speaker for expansion plans, for example.Technically, the S 30 offers the familiar 170 mm bass-midrange driver and the 28 mm dome made of fabric composite material. Thus equipped, it casually reproduces frequencies between 34 and 38,000 Hz.Impedance (Ohm): 8.0Height (cm): 35.4Net Weight (kg): 5.8Power (Watt): 200.0Width (cm): 21.5Sensitivity (dB): 90.0Crossover Frequency: 2900 HzFrequency Range: 34 Hz - 38 kHzDepth (cm): 27.0Bass Reflex Port: YesOriginal Colour by Producer: WalnutSystem: PassiveMiddle Speaker: 6,5"Tweeter: 1"Set Content: 2 pcsSensitivity: 90 dBPower: 200 WPackage Contents: ManualPackage Quantity (pcs): 2Power RMS: 100 Wype: BookshelfHF Driver Type: Dome TweeterRemote Control: NoPower-Amp Built-In: NoBluetooth: NoMade in: ChinaColour: BrownHousing: MDFImpedance: 8 OhmBandwidth: 2 Bandwidth.
