With the Goldi. As mentioned Bass response will probably be an issue. Another has to do with the speaker being a 3 way. You generally need a fairly large distance between speaker and listener for the 3 drivers to sound integrated properly when they reach the listener. These are basically the reasons a monitor or small 2 way floorstander are the speaker of choice for a small room.
