I have a small system in my computer room which is about the same size as your room. My computer desk is right up against the front wall, so I'm very near field. I have the speakers in the front corners of the room, about 1 foot from the wall and angled towards me at a little less than 45 degrees. Wood paneling, no treatment (yet, hoping to pick some up this weekend), sounds great! It doesn't have the sense of scale of my main system, but in terms of sound quality and clarity, it sounds as good, if not better. Speakers are Harbeth P3ESR and I have a small SVS SB12-NSD sub on the floor next to my desk.
Is it even possible to set up a system in 12x12 room?
I am moving next week and there is an extra room that is 12x12 with 9 foot ceiling. This will not be my main system but I have an extra gear I would like to use. I have never set up a system in a square room and definitely not this small of a room. I have a couple pair of 8 ohm 87 db monitors that go down around 40 to 50hz and a pair of 6 ohm 87db floorstanders that go to 27hz with ports in the front. I have a el84 tube amp that is 25 watts and a 150 watt solid state amp with a tube Preamp. The couch will have to go directly on back wall and may be able to pull speakers 2 to 3 feet off front wall and maybe a foot or so off side walls. Is there anyway to make this enjoyable to listen too? I know I'm going to have to treat room but where would panels perform best or am I wasting my time?
