Band-pass horn-loaded bi-amplified active subwoofer.
Designed for live music performed in medium to large venues where the main requirements are extended bass response and maximum sound pressure. The company's pioneering approach to acoustical design combines the theory of wave-guides with that of band-pass systems and the mathematics of organ pipes with that of low-turbulence exponential reflex ports. All of this is carved in the wood, without compromises. This relationship between art and science is completed thanks to an innovative 18" woofer, which embodies a new technology that makes it possible to drive a new-geometry voice coil in a linear manner over a ±30 mm excursion. Moreover, multiple heat dissipation systems help to control and minimize the power compression effects up to the rated power level. The result is the higher Maximum Output Level rating for a subwoofer of this size, weight and power. Power and control, without compromises, up to the last watt.


The unusually low distortion and the unexpected long throw of model MOL1818A 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. Particular attention has been focused on efficiency and tonal neutrality.
MOL1818A SubOne, thanks to its performances and ability to effortlessly reproduce extended low frequencies, may be used as the low frequency speaker in the PalcoPLUS line-array system in place of the RAB1815 cardiod subwoofer.


The extremely sturdy cabinet is built with 18 mm birch multiply covered with an anti-scratch surface finish; it is fitted with internal driver-protection grills, castors with brakes and carved out handle cavities on both sides of the cabinet.
