This acoustic concept has the effect of considerably reducing load volumes and achieving an excellent size-to-low cut-off frequency ratio; all with an acoustic efficiency gain of at least 2 dB compared to conventional direct-radiation bass-reflex baffling. The UC115B loudspeaker cabinet features four integrated handles, four connectors (two front and two rear), a pole mount socket, as well as a captive 4-point mechanical connection system designed for flying vertical arrays of UC115B cabinets alone or in combination with UC206N/W loudspeakers.

The UCTRUSS element is the common mechanical accessory for Uniline Compact cabinets: it is used to suspend simple or combined configurations between the various UC206N, UC206W and UC115B cabinets. The UCSTACK is the accessory to be used for stacking cabinets
UC206N /W either directly from the floor or to UC115B units.
