I have a room bigger than that with a balcony and cathedral ceiling and I use my Polk Lism707 and they sound Great and so do other people ,I have had over Ok there not Audiophiles, just human beings ...lol.
Speakers for a Large Room (20’x37’)
Open concept listening space with speakers on one short wall and kitchen at the other end. Furniture about fifteen feet from speakers. I assume I'll need large speakers and am considering Klipsch Cornwalls as well as Tannoy Ardens, but open to suggestions. I also assume standmounts are too small for the space. I should mention I mostly listen at low to moderate sound levels, occasionally cranking it if the wife is out. Thanks for any input.
