OK thanks. Yes my room is NOT ideal for two channel audio. It is the Great Room (14.6 x 18.10) - but there are no walls separating it from the Dining Room, Kitchen and Gathering Room. So, it is rather large - 1000 sq. ft. or so overall. So it should be fine.
So, I don't think it will be like the Sahara Desert - as another poster stated elsewhere.
So, heat won't be a problem. But I will have plenty of other room issues to tackle after system is installed.
Thanks Again!
