UC118i
Infra-bass speaker - Installation
Néodyme 1 x 18'' driver, 4'' ventilated voice coil
Complex band-pass load
The UC118i is a very low frequency subwoofer. It is fitted with one convection cooled Neodymium 18" transducer loaded by a double interactive chamber acoustic load.
This type of load results a 3 dB gain before feedback and reduced distortion thanks to excellent control over the diaphragm displacement. This, combined with the convection cooling technology used with the neodymium woofer, means that thermal compression is reduced by nearly 2 dB. All these optimizations lead to impressive dynamics and avery high maximum SPL.
The ergonomics of the UC118i are particularly well developed to enable easy mounting a maximum of 3 subwoofers. The enclosure features a fully integrated 2-point rigging system, recessed handles, two rear connectors and two front connectors dedicated to wiring of cardioid configurations. The subwoofers are attached to each other our ELK (Easy Link Kit) connection piece. The BUMPER allows the suspended use of all UC118i subwoofers (3 UC118i max). The use of APG digital processor is mandatory for UC118i.
