Uniline Series UL118B Dedicated UNILINE subwoofer One Neodymium 18" driver with 4" ventilated voice coil Complex band-pass load Features Very low frequency range High efficiency and high power handling Captive mechanical and rigging system Applications Complex hanging and/or stacking bass system Very low frequency sound reinforcement for Uniline system Cardioid and/or sub arc directivity applications Specifications 25 Hz - 80 Hz 800 W AES 102 dB SPL @ 1W / 1m 137 dB SPL Max @ 1m 8 Ohm 20.9" x 27.6" x 29.7" (530 x 700 x 755 mm) Single channel amplification Processor mandatory The UL118B is a line array 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 a very high maximum SPL. The ergonomics of the UL118B are particularly well developed to enable easy and efficient combination with all the other Uniline system elements. The enclosure features a fully integrated 4-point rigging system, 16 recessed handles, two rear connectors and two front connectors dedicated to wiring of cardioid configurations. The UL118WB transport dolly will take up to three UL118Bs stacked and secured to the wheelboard by the rigging system. An optional cover is available for two UL118Bs. The ULTRUSS bumper is compatible with all Uniline loudspeaker elements whilst ULSTACK accessory is designed for single array, small format Uniline systems. The use of APG digital processor is mandatory for UL118B. The UL118B is the dedicated infra-bass subwoofer of the APG Uniline line array system. Its sophisticated ergonomics enable easy, safe and intuitive transport and handling. The integrated 4-point rigging system is designed to enable cardioid configurations with multiple speakers inverted within a vertical or horizontal array. The rigging system allows all types of installation: Flying a single cluster of UL118Bs or complex groups combining UL118B and UL210/D. Indeed, the UL118B are perfectly designed to be coupled in a vertical array either with other UL118Bs or in combination with UL210/D line array speakers. Thus all bass system configurations are possible, from horizontal or vertical line arrays, to cardioid or arc configurations, or even cardioid arcs, flown or groudstacked. Lifting and flying UL118B clusters is performed with the same bumper and accessories as the other Uniline system elements. The UL118B is aimed primarily at sub-bass reinforcement for the Uniline system, but is equally compatible with other APG speakers, such as the Dispersion range.

Frequency range without processor (±3 dB) 35 Hz to 110 Hz Frequency range with processor (±10 dB) 25 Hz to 80 Hz (1) Enclosure Components_ Type of load Band-pass Power Requirements Recommended Amplifier (2) Peak AES (3) (1) The UL118B frequency response is generally limited to 80 Hz. However thanks to the processor it is adjustable between to 60Hz or 110Hz depending on the system configuration. (2) In order to take full benefit of the dynamic performance, sonic quality and reliability of the speakers, the recommended amplification must at least correspond to the AES rating. Lesser...
