Doubting Sound Treatment ?

Rack along a side wall vs centered between speakers

Correct, worst thing you can do for imaging and depth perception, is have your equipment between the speakers. Speakers at least a min of .5 to 1mt in from the side wall, and as far out from the from the back wall as you can, if? you don’t need the extra bass loading the back wall can give.

The mighty SR duo shillers have surfaced from the mire, the other 4 will be along shortly, to combat any negatives on the HFT little snake oil thingies.

I shine the light on all forms of BS sunshine.

Better improvements with the treatment than most of us hope for when we change Preamp, Amp, or Speakers. Doubt no more !

Proper room treatment with acoustic panels, corner blocks, traps ect work a treat.
Just stay well away from expensive BS snake oil voodoo things like Shun Mook pucks, little dots, little bags of rocks and those expensive little HFT things, they are just a money grab aimed at the gullible, who couldn’t be bothered doing the work with proper acoustic treatment.

And get the acoustic panels, corner blocks, traps ect from places that sell them for recording studios cheap. Like this one in Australia, There are even cheaper ones.
