Speakers for a very large room?


Reader of posts for a few years but have not posted a serious question until now. Currently have McIntosh integrated tube amp with some old KEF speakers. While I enjoy it in my current setting, I am moving to a house where my listening room will be 30' x 40' x 10'. It has polished concrete floors. Sounds like a grocery store but it is not. I suspect I will need to change speakers but really have no clue where to start. I listen mostly to progressive rock but also anything in the same general area. I don't know where to start with such a room? I am at least 3 hours from any major city. I did experience Treo CTs once and to bright for my ears and Wilsons but did not care for the visual appearance though liked the sound better. It was a few years ago so can't better define what I liked.  Not a great resume of listening experience but it is what it is at this point. For some reason, which may be completely wrong, I am thinking electrostatic may work well in this setting. I could easily move them 5 feet out from the back wall but then again I really don't know what I am talking about. Any kind comments would be appreciated.

I would say that working with your SO is going to be critical here. I'm not an experienced audiophile but a room that large with concrete floors is bound to be a sonic challenge. Working with your SO to make the acoustic treatments things that she likes or will tolerate would be the way to go IMHO. I'm talking about rugs, heavy curtains, even decorative rugs hung on the walls.

Also, is there an option for creating a room within the room? Possibly using acoustic panels, furniture, etc to create a smaller more focused listening space? Or is the goal to fill the entire room with sound?

for your type of listening, after tackling room issues, you might want to consider multiple subwoofers...like The Swarm
Check out the larger Ohm Walsh speakers. They work well in large spaces! Call John Strohbeen at Ohm Acoustics in Brooklyn, NY. I use a pair of the Sound Cylinders - remarkable 3-D imaging and performers right in the room!
