Any heard of Sound of Science room treatment

I’ve seriously considered ( after many  years & ears ) to treat my room with broadband panels along  walls.
Obviously there are better and worse, does ” Sound of Science ” mean anything to You?
Believe it’s a Belgian company suppose to have great effects on 250 hertz and uppwards  Any experience, I’d be deligted to hear 👍
Happy midsummer!

Respect Corona 😡
Great name for a song .... ;-)
I don't know them.  I rely on GIK Acoustics.  Great prices, fun Art Panels, very effective.
Look into Stillpoint Aperture panel not cheap but the best by far in my system.Good luck whatever you get though.
