ceiling hanging acoustic absorbing (ready made ) any available?

I want to hang something from my ceiling above my desk and speakers to absorb the sound.

I have no DIY skills, so I need something which is ready made.

Will one of these bass traps do? and can I hang it about 20cm from the ceiling somehow?
