Bought it to complement my Tannoy 502.
The sound is excellent when in low volume mode, but as soon as you try to push it a little bit a tumblring noise appears, so it went back thanks to the excellent service from Thomann.
Now I've requested a Behringer B1200D Pro. It serves for indoor and outdoor purposes and I'm much better served pairing it either with my B108D or my Tannoy 502.
