Stillpoints Aperture or Synergistic UEF panels Which one?

4 months ago I ordered 4 Stillpoints Aperture 2 panels from Music Direct since they offer 60 days returned to try out if they would do anything for my untreated listening room in my basement. Like you I experienced the placement all over my room and so far I have found my room sounded best when I placed 2 panels right in the middle of the back wall,death centered between the speakers, the top panel about 5” above the high of my floor speakers and the 2nd panel right underneath it (vertical). The other 2 Panels I placed each of them on first reflection points (on the custom wood stand I made same highs with my speakers) I probably need to order 2 more panels for first reflection points for your set up. They are a little expensive for Their size but the result is mind blowing Improvement for my room soundstage.

monoblocknova,
Thank you for your posting. Behind my listening spot I built a huge CD rack that holds about 6000 cd's. It is about 15 feet long and about 6 feet tall. I'm thinking that this rack provides the scatter effect. 
But, now you got me thinking....

I can't believe how much Stillpoints wants for the panel racks. Great thing you were able to make a DIY panel holder. 
I ended installing mine on the wall about 14" off the ground with one on top of the other covering about 44".
I think you can see it on my systems page.

Since my back wall behind the speakers was just a blank finished drywall so I had some fun with difference placement .first I put them on chairs ,wood block, 3M table on the almost everywhere on the walls,corners of the room but when I placed them Vertical dead centered on the back wall 2 panels , that where they are going to be for good . My audiophile buddy came over to help me out with the experiment project because it good to have somebody with a little passion to help out . We were shocked how much difference when we were moving them around and we were both agreed when the 2 panels centered on the back wall bring the most improvement by a big margin.

Glad to hear you found the best spot.

I would like to add that with the Apertures the HFT's on the speakers are not necessary. In fact, it sounds more natural without them.

Im glad you realized Apertures are the best HFT basically a bad joke.They may change the sound but not for the better.Enjoy!!
