I've just tested and compared these three systems, playing the Roland SonicCell and BK-7m factory demos really loud at at least 60% maximum volume.
- HK Lucas Nano 300 with 2 tops (center of the picture)
- 2x db K300 (grey speakers left and right)
- 2x FBT J5a (one black, one white speaker).
Guess what my conclusion is...
