This is just a review after only 2 weeks of use but we are delighted with the purchase. The sub is connected directly to the mixer then redistributed to two passive speakers - which can finally breathe a little. The whole setup is perfect once the intensity of each is adjusted - whether in the apartment or in the party room. The power of the sub split between two knobs sub and main level is very convenient to control everything and bring the ideal touch of vibration or power - a small downside maybe on some gaps a little too big between two notches. The whole thing looks very solid, compact (the 30cm width allows us to integrate it into the furniture) while remaining light enough to carry alone (21kg). We were afraid that a 10p would frustrate us but for our use, it is laaaargely powerful enough to meet the needs of a small room (80m2). nb: it is absolutely not gray as in the picture but completely black.
