Room Acoustics: Where to place the squares?

Thanks Eric also.  Your continued insistence on the importance of room treatments for significant sonic benefits has moved me from buying minimal to treating it like it's a necessary component.  But I may have to take a measured approach because I plan to move in a few years and don't want to end up with many unused items.

Um, I'll bite. Let's say you have 5, 2'x2' squares.  You must have been in a hurry and not included that.  That is inadequate to treat a room.  Even 10 of them.  So, put one behind your head, one on each side of your speakers, that's 5.  Stack the rest in a corner.  Don't isolate the reflections in the room, you don't have enough stuff. Isolate yourself from the reflections, easier and better. 

All written above ^^^^ is good advice, I went with ATS panels - found them on my local CL site. Spending the $$$ without sure of the outcome was questionable for me at first - where to start, so I went used. May not be the best choice if your music room is your Living room. I have a dedicated room, so didn’t t really care. Yes, everything counts in the audio world if you’re listening for it. I am now checking out Bass Traps.

Here are two good reads that my son sent me as I went down this path - he is an audio engineer, with a couple of Grammy’s to his credit.

more than necessary for a home environment but will certainly help you
