I am looking for a quality sound bar in white, so I would like some advice. I'm hesitating between the beam 2 with 2 one SL or the arc, as the price would be the same? which is the best investment? The sonos Arc tempts me because it has speakers directed upwards, something that the beam does not have, but perhaps by adding these 2 SL that could cover this defect and the sonos ecosystem is almost more complete just lack the SUB? When will Digitec make a new offer of the ARC at 699 chf like in November :-)
