Description

The LB28 is a low-frequency line-array module for larger sound reinforcement applications; It is designed as LF array extension of the LR28 pro-ribbon line-array.
In combination with LR28, very high output arrays can be formed for high-end sound reinforcement, where precise projection and long-throw is required down to the lower frequencies.

Adding LB28 modules enlarges the array length, extending the controlled (cylindrical) projection of the LR28 down to the lower frequencies, while increasing throw of the low-mid frequencies over distance.

The LB28 consist of 2 long-excursion 14” woofers with reinforced cones in a centrally-vented configuration. The Neodymium motor-structure of the custom-designed 14” features a large voice-coil and dual-spider suspension with forced-venting, for improved heat dissipation and reduced power compression.

For full system performance, the LB28 is driven and controlled by the ALC amplified loudspeaker controller; Driven by the ALC, the LB28 delivers maximum sound quality and output power with long-term operation reliability. The integrated factory presets in the drive processor of the ALC offer gain, phase and filtering matching, as well as array-length correction in combination with the LR28 system.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the LB28 and ALC, significantly increasing response accuracy of the low frequencies. This offers a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load (system damping factor of 10.000).

The rigging system is fully compatible with that of the LR28; It enables angle-setting on the cabinet without lifting the array, resulting in safer and faster set-up with minimal handling. The flying system supports different ways of array assembling and has a WLL of 32 cabinets under 10:1 safety.

The LB28 is part of “The Ribbon Network” inventory and comes with a 6-years “no hassle” warranty.
