If I can keep the dimension under 12" for height, under 8" for width, and under 10" for depth it's good.
I will be listening mostly movies, like 70%, and 30% music.
I have only heard Bose, Polk, and JBL speakers in the past. Since I am not an audio guy I couldn't tell you which one was what... That's why I am having a hard time deciding which brand to get when prices and size are so close to each other... and that's why I am here
Sound characteristics? Hmmm, somewhere between warm and flat is good.
