The Flex Pro4 with broadband driver is a new development by truePHASE and is, soundwise as well as visually, a true revelation.

The silky smooth and natural reproduction of audio one searches in vain in proAudio PAs.

With the associated Sub10, applications are very versatile.
Specifically designed for high profile applications like galas, restaurants and conferences where
focus is on quality and finesse.

But also handling is an important point. That’s why the Pro4 offers several possibilities with
its 4 x M8 connectors, one on each side.

Due to its unique design the Pro4 produces a unusual full sound, regarding its size and look.
