| 6 corners filled with Auralex cubes, all I could afford. room and full front wall also treated, bass is clear-not single noted-, image width and height (ceiling also has 2 clouds) all good for my purposes. I have no ring effects whatsoever, no flutter and no apparent resonance at moderate playback levels, just a small dip due to some phase issues at around 50hz. this is what I'm interested in fixing. I tried moving around lifting it up and changing phase of the sub, but nothing. sub is sitting on a "great gramma", is turned around 25 degrees and is 60 cms left from the middle of the room. for some reason Focal suggests placing it at a corner, sounds crap there, moved it back where it loved, put the cube back in the corner.
how bout material and thickness specs? |
