One of the issues JBL was most keen to emphasize was that of weight, or rather lack of it, for each Vertec VT4889 enclosure weighs only 69kg, including rigging hardware. Each enclosure includes two lightweight 15" low frequency loudspeakers, four powerful 2250H 8" midrange frequency loudspeakers, coupled to RBIs (Radiation Boundary Integrators), and three compact 2435 high frequency drivers fitted to WaveFormers.
The system is already establishing a strong following, both in the US and Europe, where some of the key touring supply companies have systems out with a number of headlining bands.
