Bandpass-horn subwoofer. Designed for live music performed in medium to large venues where the main requirements are extended bass response and maximum sound pressure. The unusually low distortion and the unexpected long throw of model MOL1818 SubOne when compared with subwoofers having the same size and power rating makes it possible to achieve very high levels of performance from a smaller number of units. Features frequency response of 35 Hz - 120 Hz, max SPL 144 dB, 2500 W power and two 18 '' woofers. Dimensions: 116 x 61 x 90 cm. Weight: 108 kg.
