Hi 8th,
My room is about 17' wide, with speakers centered and 8' apart. If I wanted to use Adapt rectangles at the front wall/ceiling junction, it seems like I have a few choices with pros/cons for each: (BTW, using VR4JRs, so not a dipole).
1) Single rectangle centered between speakers - This would treat the area directly in front of me, but the junction directly behind each speaker would be untreated.
2) Two rectangles, one directly behind each speaker - This would leave a gap in the middle of the room directly in front of the listener, but would do a good job on the sound coming from each speaker.
3) Two rectangles, centered, touching - The ends of the rectangles would be even with the speakers, so I'd get good coverage between them, but no coverage outside the speakers.
4) Three rectangles, centered, touching - This would give a nice 12' countinuous run which extends 2' beyond each speaker. But now things are getting $$$ for me. Or, these 3 rectangles could be spaced apart some.
Given the above scenarios, can you please comment on the effectiveness of these approaches - I assume that three rectangles would be the best for this part of the room. (I know, things are not always predictable in each room). I'm especially interested in 2) vs. 3): Leave a gap in the middle to spread the rectangles apart, or ensure that the area in front of the listener is treated?
My guess would be that there will be roughly a linear relationship between # of rectangles and the amount of improvement - Just not sure how to optimize placement given 1, 2, or 3 rectangles.
Thanks for helping me with this thought experiment!
