Uniline Series UC115B UNILINE COMPACT bass speaker One Neodymium 15" (4" voice coil). Dual Interactive Chamber Pass Band Features Flexibility & Compactness Captive rigging system Low distortion vs high dynamic range Applications Uniline Compact low frequency extension High quality reproduction in low frequencies Cardioid and/or sub arc applications Specifications 40 Hz - 160 Hz 1100 W AES 103 dB SPL @ 1W / 1m 139 dB SPL Max @ 1W / 1m 8 ohm 16.5" x 21.3" x 23.6" (420 x 540 x 600 mm) Single channel amplification Processor mandatory The UC115B is a line array low frequency speaker that allows acoustic and mechanical coupling in the vertical plan. It is fitted with one Neodymium 15" woofer loaded by double interactive chamber (The APG band pass load). This acoustic concept offers the advantages of reducing substantially load volumes of the cone driver and increasing the ratio size versus low frequency cut off. Moreover the efficiency increase by 2 dB gain in comparison with a conventional bass reflex and direct radiation subwoofer. All ergonomic functions are integrated: 4 point captive rigging system, 4 recessed handles, 4 connectors (2 rear and 2 front for wiring of cardioid configurations), 1 socket. The UCTRUSS bumper is compatible with all Uniline loudspeaker elements: it will be used for hanging of big clusters of UC115B and/or UC206N /W. The UCSTACK accessory is designed for little and simple arrays in stacking mode either on bass speakers or directly on the floor. The FCUC115B flight case allows transport of 2 UC115B. The use of APG digital processor is mandatory. The UC115B is the dedicated bass speaker of the APG Uniline Compact Modular Line Array system. It is characterized by its excellent ratio size vs SPL. In terms of sonic reproduction UC115B allows precise bass reinforcement exempt of distortion but with great sensation of impact. Its sophisticated ergonomics enable easy, safe and intuitive installation, handling and transport. The UC115B can be set up in ways: in groundstack directly on the floor or on stage (as a compact size FOH system, in side fill or a plug & play rental system), in flown assembling of single cluster of UC115Bs or in combination with UC206N /W. Thus all bass system configurations are possible, from horizontal or vertical line arrays, to cardioid, end fire or arc configurations, or even cardioid arcs, flown or groudstacked. The integrated 4-point rigging system makes easy cardioid configurations with multiple speakers inverted within a vertical or horizontal array. Lifting and flying UC115B clusters is performed with the UCTRUSS bumper and accessories as the other Uniline Compact system elements. The UC115B is aimed primarily at bass reinforcement for the Uniline Compact system, but is equally compatible with other APG speakers, such as the Dispersion speaker series. When infrabass frequency reproduction is required, UL118B, TB118S or TB218S can be coupled with UC115B.
