TheElectro-VoiceMTL-1X is a 1,200-watt subwoofer loudspeaker system which combines the attributes of both horn-loaded and vented box designs. The MTL-1 design utilizes the unique double Scoop cabinet construction , as used in Array concert systems. The design behaves like a horn over much of its range, but without the time delay and weight problems usually associated with LF conventional designs. Vented-box principles take over for the lowest octave and assist in producing exceptionally high levels of clean, punchy bass from a smodest-sized box.
