room tuning 12ftx12ft room

hello, my first post. i have a very small room, 12ftx 12ft. i have the speakers where i think they sound pretty good except for some boomieness in some bass areas and even cut-out of bass or maybe room overload when i start to turn it up a bit. but anyway, i have 4 2"x4ftx2ft framed insulation panels behind the speakers, 1 on each side of the speakers (using the mirror trick) and 2 directly behind me, with maybe a 2" gap between them.

i've thought of covering the wall behind the speakers completely floor to ceiling and coming out on the side walls 4ft floor to ceiling. then just leaving the two panels directly behind me. does that seem like a good idea?

thanks

A couple of thoughts:

1- 12x12 is going to be problematic no matter how much you treat. Try shortening the effective dimensions of the room by adding a bookshelf of LP racks to the back wall (behind you). If you arrange it properly, it will act as a diffuser. While it may seem counter-productive to make the room smaller, the dimensions are working against you more than the size.

2- Wall or corner placed speakers are small room friendly, as are horns. Choosing a speaker that can be placed directly against the wall will also allow you to buy back some real estate that you lose in the first suggestion.

3- What Rrog said.

Let's face it - if you are into full range music (and who isn't?), small rooms are tough. And frankly, square rooms just suck unless they are very large. Based testing and experimentation in my own lilliputian space, I will take (for example) a 12x9.5 room with good dimensions over a 12x12 room any day. I was never able treat a square room well enough so that I enjoyed listening in it. But that's just me.

My second point regarding wall proximal speaker placement - to each his (or her) own. In a 12x12 room, how far apart do you intend to seperate the speakers? Let's assume a modest 7'. So unless you are going to listen in the nearfield position (always an option) you are going to be approx. 1' off the back wall; probably a little more. If your room is multi-use and you are mostly watching TV that's OK. For critical listening, maybe not.

Try a variety of suggestions and see what works best for you.
