musicality17, my room is very small...10'X11', the only saving grace is that it has a 15' vault ceiling.
The Mini's in this room did not overpower the room, however, they were not a great match either.
I suspect the width of your room will be a problem, unless you listen in the near field. The G's are a much better match in my room, although I think none of these room sizes is desirable.
BTW, Wsalm, my dealer here in the US is currently closed and when he re-opens, I will ask his ok to disclose him to you. I presume that your dealer in Hong Kong would not let you home audition. IMHO, if you are contemplating a purchase of this sort of money, then a home audition is a must if at all possible. If the dealer balks, but has the product available, I really do not think that says much for them, and I would personally look elsewhere.
