For this review I removed the Corner Treatments I had auditioned and installed the Seam Treatments as instructed,vertically in the corners of the room, midway between floor and ceiling.
In my room this treatment improved the highs more than anything else. Cymbals were crystal clear, every splash, brush, or strike was amazingly crytal clear. It improved vocals , and other midrange notes to a degree and slightly improved the bass by giving it slightly better separation.
I would say the Corners made a more dramatic improvement to the midrange and the bass, the seams made more of an improvement to the treble and the highs.
I still have not compared with both treatments installed. I am trying to give each piece a separate audition and will report on the entire room treatment in the review section later.
