Pass X600 Will it heat my room too much ??

I have a pair of XA100.5's in a 16x20 ft room. The 100's put out 600 watts of heat at idle and yes it does heat up my room. I had a pair of XA60.5s before the xa100.5's and I could not tell much of a difference with them, but with the XA100.5's I can. The X600's will put out 1200 watts of heat at idle, thats like a portable heater. I believe alot depends on your tolerance of the added heat and how good your air conditioning is in the room, as for me I have not had the XA100.5's during the summer months yet, bought in October, so the jury is still out on whether they will stay permanently in my system
