Stillpoints Aperture or Synergistic UEF panels Which one?


Stillpoints Aperture or Synergistic UEF panels Which one?
Both of these products have received rave reviews. The Stillpoints appear to be 4 times the cost of that of the Synergistic Research.

Currently, I am using some convoluted foam panels at the first and second reflection points and I also have many of the Synergistic HFT's through out the room. I also have ASC bass traps in all 4 corners.

I just tried a SR HFT in the center of the acoustic convoluted form panel and son of a gun it did lock in the soundstage. So, now I would like to pursue further with trying either one of these panels.

I have read somewhere that the SR HFT's do not work well with the SR UEF panels, which to me seems strange.

Any opinions would be appreciated.

Just received my (2) Stillpoints panels that I purchased. They are in a black frame with black grill cloth, looks real nice.

I’m going to take the opportunity while still having the 2 demo panels to experiment. The blacks ones are at first reflection with the bottom of the panel at the bottom of the tweeter. Which seems to sound the best thus far. (My Sopra 2’s have the tweeter below the midrange). At this moment I placed the demo units under my black ones.

I still have some black convoluted foam at the second reflection, and ASC bass/tube traps in the corners from floor to ceiling.
Is 4 better than 2? We shall see.

Just ordered an additional 2 more Apertures. What surprised me the most when I tried 4 of them was how much bass clarity and depth they provided.
Expensive yes, but do they work well!

Now that I have the 4 Stillpoints Apertures placed. (I have 2 on the left and 2 on the right at first reflection), there are noticeable improvemnts in very familiar recordings.

Example:
"Green River" by CCR in 24/192hz I must have played this song zillions of times.
I now can clearly hear Tom Fogerty playing rhythm guitar in the center channel. Before the Stillpoints it was barley perceptible.

morningstaraudio,

yes,
I experimented  with them in so many different ways. Stillpoints also said to cover the drivers which ended up requiring a total of 4 of them. 
Plus, I still have 20" round ASC tube traps in the corners.
