* Yes, I currently use acoustic room treatments in my home theater.
* I use acoustic lens reflectors for sound propagation and spaciousness.
And I also use absortive materials strategically positioned in the room.
Oh, and I build my own acoustic room treatments.
* I wish to have a better system to integrate the low frequencies to my room, like a better subwoofer(s), for example.
I did have fun, now, I just need luck.
