I'm moving into a new place. I have been using headphones forever, but I have the ability to use monitors now, so I've decided to go with the Yamaha HS8s and the HS8S sub, as I mostly make bassy music, and have an understanding that they have a very flat response and good quality for the price range. The problem is, i'm worried about acoustically treating the room. The room is pretty big, and akward shaped. I will be sharing the room with my wife, so i'll only be making noise when she is at work and I am not, and it's going to be tough to convince her to let me hang a bunch of acoustic treatment stuff, as it will ruin her decor(Women! ...Sheesh). I have two main concerns.. Will I need the 8" cones, seeing as how I'm getting a sub? Should I go with the cheaper 5 or 6.5 inch ones, or is there a benefit to using the 8s seeing as how the low end will mostly be taken care of by the sub? My other concern is about the room itself, it's a "U" shape with a bathroom against the middle of one wall. She wants to stick me in a corner, obviously. it's about 30 feet wide, with an A frame ceiling that is like 4' high on the sides and 15' high in the middle. I have heard that bigger rooms need less treatment, and she wouldn't like the look of it, unless it's vitally important. I was wondering if anyone had any input about either the subs or the room itself. I've uploaded a beautiful artistic representation of the room at imgur dot com slash NSs0gwW. Thanks for any and all input guys!
