Two sets of HFT's mainly demonstrate that they have an effect. Like you I have a QOL unit in my listening room. I sincerely hope you will order three additional boxes to really tune your room acoustics. With two sets (10 of the little bullets) of HFT's my soundstage changed but lacked focus. AS I put in the next three sets of HFT's I heard a real change for the better. As you have heard, the locations suggested in the instructions are only starting points. With additional HRT's in place you might move the units up or down from where they are now.
I am finding the combination of the HFT's + FEQ unit with the BSG Technologies QOL unit to be sonic bliss.
