There was quote from Fortress but found they removed the product month ago. By the way, this sound projector does have one audio bean reflected from the ceiling. I went to Tom's showroom month ago and found it fairy good. Frankly, in terms of the apartment size in HK, I can't find anything else that can tick all my boxes like this. However, I would go for 4100.
BTW, what do u think about the Blue Ray players such as OPPO83, Panasonics DMP-BD85 & Poineer BDP-LX53? Which is better to connect to YSP for trueHD audio... I haven't experienced such simulated 7.1 in TOM's showroom.
