JBL VERTEC is a fabulous system since now 7 years (2002) from real factory JBL (where they build there own loudspeaker while others, nearly all, never have built one loudspeaker)and the greatest audio knowledge in the world audio pro industry.
Now with the V4DSP presets, it's more easy to use this state of the art sound system to obtain a greatest sound, certainly the better line array.
We see JBL VERTEC on the greatest tours and prestigious concerts from classical music to rock and pop stars ALL OVER THE WORLD, there is a raison, non ?
The stunning sound.
