Bass is heavy, that is the biggest minus for transporting. Anyway thats the only one minus after one hour of playing. In total I really like the sound, quality of build. P.S. The shipping was really fast, it took 5 days!
Update. The sub was broken more than 2 times, Im not sending the item to thomann anymore, because DPD made damages to it. Subwoofer burned out 2 times, and it was fixed, after fixes vibrating as hell... There is no point to buy this item, because it has no safety resistors.
