If you have a rectangular room who have to try this out. I came across it on the Cardas website. I thought my system sounded fantastic already, but this mathamatical calculation for speaker placement made my system completely open up. I was dumb founded at the before & after effect. I kid you not!! My room is 13x32 & it has never sounded better. If you have the room - DO IT!! He also gives speaker placement calculations for other shaped rooms. Check it out!!

Hey!

    Yup, been there. Tried that. But didn't work perfectly with my speaker.
 
    I did ended up using pretty much the same distance from side wall as suggested by the Cardas auto calculator. So, I guess it did work some what but not 100% as suggested. Don't know why

     But still I agreed that everyone should try it. Well, it might work for some If it doesn't than just move your speaker back.

Take care,
Buddy

Well I've no doubt about that. You obviously know the benefits of room treatment. If you want to take it to another level you may want to try the Behringer DEQ 2496 to iron out the peaks and dips some more.

My room is LEDE with four bass traps and the Behringer still made a huge improvement.

Cardas was not the first by any means, but he certainly took it to another level by giving it a mythical aura (that's called good marketing!), "Golden Section"...how can you go wrong? The Romans and Greeks were masters of psycho-acoustics and in spite of all the advances in this "science", creating concert halls gives people serious migraines, to say nothing of the difficulty in recording in existing spaces. I've personally tried over the years to apply, as best as possible, these principles in various rooms with various degrees of success. I guess what we mean by the sweet spot is nothing more than locking into the "correct" ratios and nodes so that the room is participating in making music rather than fighting it.
When this happens, the room "sings" so to speak. What works for on pair of speakers will probably not for the next and we get to start all over again! I remember a seriously maniacal attempt to get a pair of Maggies to sound right in a room. I ended up using egg cartons glued to the ceiling (they kept falling down). Ideally one would build a room from the ground up but I fear this might again only work for certain kinds of speakers. At present I'm lucky to have a very "forgiving" space, which is just as well as I have
cheap speakers. Now that I think of it, this reply doesn't really belong here at all. Sorry, just felt like talking.

I'm fully Cardias here (Golden Trapagon with suggested speaker/listener positions).  My listening room (with office setup in the back) is 13 ft wide x 21 ft long x 8 ft tall.  We moved into this new house a year ago with the stipulation that I get this "man cave".  With single driver speakers and monoblock amps, even young "uneducated" listeners get wide eyed when they sit in "the" chair with the right recordings.  Within a foot or so of the prescribed listening location images lock in.  The effect is perhaps best described as a blend of listening to normal stereo from speakers and headphones.

I have six GIK 244 high density fiberglass 2 ft x 4 ft panels with four stacked in the front corners and the others at side wall first reflection points.  My next step is to DIY eight 18 inch x 18 inch diffusion panels on the front and each of the side walls:

The side wall GIK panels would get stacked in another corner.  Then I'd like to add a Behringer DEQ 2496 in the digital stage of the signal path.

With my office chair (that sits taller than "the" chair) about 6 feet behind "the" chair the speaker toe in is set to cross behind "the" chair but in front of the office chair (with the computer screen angles to the side) to make a pretty good "best of both worlds" setup.
