I have been using a can over 2 years now
The special-I love the most: the power delivered (see feature below) the system is very compact and very powerful!
The system is versatile because I used both to add sound of fireworks very good thanks to this open, but also concerts, public dances. . .

Like all products & b audiotechnik I like it very balanced sound. All is set at noon on the consoles. The sound is very clean and very dynamic.
The system consists of two C7 C7-TOP 4 and C7-SUB + 2 d & b P1200A amplifier or audiotechnik The D12, for me it is 2 P1200A.
