I am permanently trying to increase the audiophile and videophile performance to an optimum. Currently I am trying to enhance the sonic quality of my room. There seems to be a little too much distortion in the low frequency spectrum. I recently upgraded the room with bass foam trapps in the front facing corners and also got some additional accoustic foam from Illbruck, a german company with good accoustic foam products. It is not perfect yet, but definetely getting better. the whole room is powered on its on circuit with an isolated ground rod outside of my house, all outlets are upgraded to hospital quality. I might still get a power conditioner on top, don't know, yet. The big problem in my HT seems to be the flooring, it is all hard wood laminate, with 2 concrete walls and 2 dry walls facing each other, hard to find the optimum ballance of reflection and accoustic insulation. Has anybody experience with sound tuning of their dedicated HT room?! I will try to add some images soon. Just bought a pair of Dynaudio Confidence 5- I am looking forward to hear them and welcome them in my HT.
