Thanks Highfigh, you were correct.
I asked this question of Glenn @ GIK Acoustics, and his response was that their panels have eye hooks and supplied wires. The panels are to be suspended with an air gap behind them from another set of eye hooks not supplied.
I'm glad i asked this question as i would have hung them snug to the ceiling.
Glenn said that there would be an added benefit of bass absorption if mounted with an air gap. I'll be doing the same with every panel I get from them.
So Thanks to Glenn and HighFigh for your answers.
