Speaker Placement - When it's perfect!

Most likely expectation bias. 😀 Besides, everybody knows plants don’t affect low frequencies. Can you think of a single scientific theory why they would? Maybe there were other people in the room when you were measuring, or something else affected the measurements. Temperature, pressure, the weather. Who knows? Human beings, you know, being mostly water DO affect lower frequencies. They are terrific Helmholtz resonators. So color me unconvinced. 🙄

@hifiman5 ,

That is almost always the case, but my room is irregular, with a large alcove on one wall, and large walk-in closets with bi-fold doors from corner-to-corner on the opposite wall. Hardwood floors with a rug covering most of the floor. Bass frequencies have lots of places to escape. After covering all first and second reflection points I was happy to find out I did not  need to treat the corners.

Basically, his method is this: hook up just one speaker, and position it exactly where you will be *sitting*, right in front of your chair or move the chair and position it exactly where your ears will be. Play some music with some good bass. Get down on your hands and knees, and crawl around the approximate area where you’re planning to situate one of the speakers. Perhaps do a grid search. Find the exact position where you can hear most bass. Mark. Repeat, crawling around the other speaker position. Set everything up and enjoy.

On the face of it, this sounds intuitively right. What do people think?

(And you get a little exercise!)"

>>>The XLO speaker placement track will give the best results. Better than that method. Better than any trial and error approach. Optimizing one parameter (bass) ignores the other parameters such as frequency response (smoothness), coherence, soundstage depth and dynamics. Thus, you wind up with good bass at the expense of everything else, no? The XLO Track insures ALL audio parameters are optimized simultaneously. AND it does so regardless of room dimensions, room acoustic devices or lack thereof, etc. That’s why I frequently say that trying to find the ideal - the very best - locations by ear is a fool’s errand 😜 as one can never be sure he's found the very best locations. Plus once you change something in the room the locations you found are no longer valid anyway. Trial and error methods are like trying to solve X simultaneous equations in X + n unknowns. 😝

Well, the plant may not be a good bass absorber, but the giant pot it's in, full of wet soil and placed in a corner is probably where I'm getting the bass absorption. Or super strong expectation bias. 😁

I have my measurements and they show a significant drop in bass decay time on a waterfall plot. And I have my ears.
