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[tab]230Vac, 50Hz (IEC)[br]Construction[tab]15mm MDF with durable texture paint finish[br]Hardware[tab]2 x side carry handles + 35mm pole mount socket[br]Line inputs[tab]L+R balanced XLR[br]Line outputs[tab]L+R balanced XLR & L+R link XLR[br]Controls[tab]Output level, phase switch, high pass x-over (output)[br]Amplifier : construction[tab]Class DSub driver[tab]300mmØ (12")[br]Output power : rms[tab]400W[br]Output power : max.[tab]700W[br]Weight[tab]18.86kg[br]Dimensions[tab]480 x 450 x 380mm[br]Voice coil[tab]62mmØ (2.5")[br]Peak output[tab]1400W[br]SPL max.[tab]122.0dB[br]Frequency response[tab]55 - 150Hz
