A flat, horizontal speaker is always expected in the center under the home theater. Therefore, we have also developed this at the same time. Since the center can also be placed directly against the wall, i.e. without any distance, bass reflex tubes on the side walls are a good way to ventilate a compact cabinet. For the center we use an HP 50 tube on each side.
The damping of the center should be discreet, as already described for the Flamenco 1 compact. Half a mat of Sonofil behind each driver is a good measure.
