Lightweight yet powerful active subwoofer units with inbuilt class D amplifiers. Each cabinet is constructed from 15mm MDF with integral side handles for easy portability and 35mm socket to accommodate a mounting pole. The high flex sub driver is front-loaded with a protective steel grille to deliver powerful transients and add warmth to any sound system. The class D amplifier section has stereo line inputs and outputs to allow use either as a mono sub with stereo tops or a matching sub for each top speaker. Line inputs have a parallel Link output to pass the signal onto further active speakers and a pair of line outputs with switchable high pass filter to connect to active top cabinets. A phase switch is included to help avoid sound cancellation and time-align multiple speaker setups. Designed as a perfect match for the CASA series speakers and equally at home with other active full range cabinets.Power supply: 230Vac, 50Hz (IEC)vbCrLfConstruction: 15mm MDF with durable texture paint finishvbCrLfHardware: 2 x side carry handles + 35mm pole mount socketvbCrLfLine inputs: L+R balanced XLRvbCrLfLine outputs: L+R balanced XLR & L+R link XLRvbCrLfControls: Output level, phase switch, high pass x-over (output)vbCrLfAmplifier : construction: Class DSub driver: 380mmØ (15")vbCrLfOutput power : rms: 500WvbCrLfOutput power : max.: 900WvbCrLfWeight: 25.42kgvbCrLfDimensions: 564 x 540 x 448mmvbCrLfVoice coil: 75mmØ (3")vbCrLfPeak output: 1800WvbCrLfSPL max.: 123.5dBvbCrLfFrequency response: 50 - 150Hz
