UL115B

Uniline dedicated bass speaker

APG simple K-Horn acoustic load
1 x 15" Nd in forced ventilation (4" voice coil)

K-Horn

The UL115B is the dedicated bass element of the "Modular Line Array" UNILINE system, which also constists of the UL210 long throw speaker, the UL210D mid-throw speaker and the UL118B infra-bass subwoofer. A very wide variety of UL210/UL210D/UL115B/UL118B configurations are possible thanks to the acoustical and mechanical modularity of the system which offers virtually, an unlimited number of combinations for optimal coverage of just about any site.

The UL115B is fitted with a single high power 15" neodymium cone driver mounted in a double chamber band-pass speaker enclosure. The front chamber opens onto a K-Horn APG design. This complex acoustic load provides an optimal efficiency gain as well as excellent control over the diaphragm displacement. This combination results in a superior dynamic capacity and an SPL gain of over 6 dB compared to a traditional direct-radiating vented enclosure.
The UL115B bass speaker has been designed for low frequency reinforcement from 45 – 110 Hz. The frequency cross-over point with UL210/D can be set depending on configuration.

It is possible to extend LF still further by using the TB118S or TB218S subwoofers and UL118B infra bass sub-woofer. In applications where the bass speakers do not need to be flown, the UL115B can be replaced by APG TB115S or TB215S subwoofers. In venues or sites where speakers must be flown, it is possible to replace traditional subwoofers with UL115B bass speakers.
The ergonomic 4-point rigging system makes it easy to fly or ground-stack the UL115B. Cardioid configurations are also possible. The Uniline system is fully controlled by digital APG processing which for complete library of presets are provided.
