Uniline Compact bass speaker

One Neodymium 15" (4" voice coil).
Dual Interactive Chamber Pass Band

The UC115Bis the dedicated bass element of the UNILINE COMPACT system, which also constists of the UC206N long throw speaker (Narrow), the UC206W short & mid-throw speaker (Wide). This system respects exactly the same concept of Modular Line Array than the UNILINE. A very wide variety of UC206N/UC206W/UC115B configurations are possible thanks to the acoustical and mechanical versatility of the system which offers virtually: an unlimited number of combinations for optimal coverage, power and musicality of just about any site and events.

The UC115B is fitted with a single high power 15" neodymium cone driver mounted in a band-pass enclosure. This acoustic load gives a 2 dB gain efficiency as well as excellent control over the diaphragm displacement versus a reduction of volume and of sonic distortion.
The UC115B bass speaker has been designed for low frequency reinforcement from 45 – 110 Hz. The frequency cross-over point with UC206N /W can be adjusted depending on configurations. Thus, UC115B is suitable for any midrange FOH applications as well as for side fill sound reinforcement on stage.

It can be also used in combination with DX speakers of Dispersion series. It is possible to extend LF still further by using the 18’’ APG subwoofers like UL118B, TB118S or TB218S. 
The ergonomic 4-point rigging system makes it easy to fly or ground-stack the UL115B including cardioid configurations. 
The Uniline Compact system is fully controlled by digital APG processing which for complete library of presets are provided.
