One of Duke's AudioKinesis sets. I love it. Posting here because I only did it so my speakers would sound better, not because I wanted to fill in what my Klipsch Belle's can't do. I learned, or bought into the idea that to have good sound in your room you need to control 20hz to 200hz.
I've have 2 rythmik subs with miniDSP and it was decent. And fun to set up. I really enjoy this AudioKinesis set up. I loosely set up with the "best" positioning but limited to my existing space constraints in my 13 by 19 room. I think it's very forgiving in my room. I'm running all wired in phase and crossing over 60-70 ish. One sub with the port open. the amp EQ running flat. I'm excited to take some measurements and fine tune. I think my sound stage has greatly improved and the immersive feeling of presence is strong.
