Picture Luke Skywalker trading frenzied light sword slashes with Darth Vader (unknown to Luke his father). At a brief moment of respite, Darth Vader says, in sonorous tones..."Impressive"
Yes you are...
...almost right. I did position the speakers using a formula. Not from Cardas, but from Quad -- the place-the-speakers-at-the-one-third-point-of-the-diagonal-of-the-room formula to be precise.
And then adjust as needed.
But how did I wind up with my chair on the wrong side of the speakers?
Or on the right side of the speakers, but with the speakers pointing the wrong way?
I had a puzzle. Here was a room, one with cement, and glass. Lots of cement and lots of glass. And it was the main room of the home. And it needed to be multi-functional, with a place for the piano (the only place in the house it would fit, really) and a place for a sectional sofa so people could gaze out the really large and really made of glass window and admire the view.
And it needed a place for my stereo.
And the room is shaped (alarm bells going about to go off) like an "L." And not just in the horizontal plane. It is also shaped like an (dare I repeat it) "L" vertically, with a large, nay, expansive stairwell rising up at the end of the room.
So picture an L laying on its side connected to an L laying on its back and you may get the picture.
Now where was I -- reread the orignal post...Oh yeah
I noticed that, with the speakers placed at the 1/3 point (or, as we will all call it hence, the "Quad point") that there was, the room being rather long, a lot of room behind the speakers. So much room that I could place my chair where it needed to be and have several feet between the chair and any built-in obstacle behind it. Do I have to mention that the obstacle in question is a large -glass- window?
Things quickly fell into place. The sofa, the piano and my chair. The L shape started to work for me, moving the lateral first reflection points (on the right side a -glass- window) far away, like 20-odd milliseconds far away. Treated them anyway. Anything worth doing is worth overdoing.
And how did it sound? Arghh. But read the previous post where in I describe the tortuous route to virtous sound.
But more to your comment, the speaker positioning, as unconventional and driven by necessity as it was, follows my preferences for dipolar speakers.
Rancho Zabaco zinfandel now rages thorugh my veins. Must...focus.
Placing magneplanars in some vicinity to the rear walls is more a necessity than a virtue. We, including me in various homes, tend to have rooms that simply won't allow the speakers to be all that far from the rear wall. So we manage the backwave as well as we can and maybe get some bass enhancement from backwave reinforcement (which also means we get some bass de-enhancement when other frequencies cancel the front wave). But we deal with it.
Here I have (recognizing in retrospect) the opportunity to substantially dissipate the backwave with long random paths across 20 feet of space. This attenuates the backwave and "randomizes" it, decorrelating (uncorrelating?) it with the front wave. The bass response is preserved because the front wave is still radiating into a fixed area, it's just not the backwave radiating into the area behind the speaker that is more the norm.
All of which would be quantum dots except that I am really happy the way things have turned out. You know, reeaaally happy. Like in not wanting to move lest I lose the recipe and maybe the long wet cold dark winters aren't really that bad and besides they give me more excuses to stay inside enjoying my system and who needs heating oil anyway since the Krell seems to be doing a dandy job of heating the floor by itself.
Very Respectfully,
