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.Colour: BlackSet Content: 2 pcsPower RMS: 100 WPower: 200 WPackage Quantity (pcs): 2Bandwidth: 2 BandwidthRemote Control: NoTweeter: 1"Sensitivity: 90 dBPower-Amp Built-In: Noype: BookshelfHousing: MDFHF Driver Type: Dome TweeterOriginal Colour by Producer: BlackMiddle Speaker: 6,5"Package Contents: ManualImpedance: 8 OhmBluetooth: NoMade in: ChinaSystem: PassiveBass Reflex Port: YesCrossover Frequency: 2900 HzSensitivity (dB): 90.0Power (Watt): 200.0Net Weight (kg): 5.8Frequency Range: 34 Hz - 38 kHzImpedance (Ohm): 8.0Height (cm): 35.4Depth (cm): 27.0Width (cm): 21.5.
