When PT came to my house yesterday, I never heard the sound stage and 3D feeling like that in my house that's great thx for PT expertise and the 2ps sliver resonator and diffuser. Before that room acoustics treatment, my room has a most reflection on my listening point. That operation is success to save my systems. Which experience tells me can recommend who is leave in small house and the listen point is quiet near the speaker.
Just my little sharing!
