Room acoustics

How about a thread on room acoustics and ways to improve the in-room performance of your system and its speakers? Subjects covered could be the physics of room response, measurement of response in your own room, and how to deal with imperfections, above and below the Schroeder frequency, like damping, bass traps, speaker positioning, (multiple) subwoofers, and dsp equalization. Other subjects could be how to create a room with lower background noise for greater dynamic range, building construction, or what to do in small rooms.
I am a bit busy just now, but as soon as I have time I will try to kick off with some posts and links.

Indeed Randy (I have an open plan as well), but real life rooms are almost invariably more complex than simple models. Therefore, rather than measure dimensions, I prefer to measure (and adress) the response.

Oh, @willemj  , we can't post pics directly in a thread on this forum. You'll have to post pics on your systems page or on any image hosting site, then put links in your posts on this thread. Not optimal, but..

And I completely agree, great thread. It seems this is more technical than most want to deal with around here, since it involves more than purchasing an item and installing it.. but we do have many members who like to dig in and who are incredibly knowledgeable, so hopefully this thread will bring that knowledge out.

OK, maybe we need to look into that then, because graphs are very illustrative of potential problems. Most telling are waterfall graphs, as these show that peaks also linger on. If people talk about slow bass performance of a speaker/sub they are wrong to blame the speaker. It is the room that makes the sound linger on. And that is very audible.

I have to sign off now (it is evening where I live) because I am expected at a birthday party. Please continue.
