Square room Soundstage??

Ok the last two posts seem very helpful. I think I will try room treatmemts before amp re-cap or power cond. ok I have found some pretty cheap pannels and bass traps. Can I go with cheaper or ones or are they complety worthless. also I get the mirror method but do I use this method with bass trap and accoustic pannels. If put pannels and and. bass traps in corners behind speakers how do I position. Bass traps in the corner on the floor with the pannels directly behind speaker. Then mirror method method on first reflection?

Darkstar - read over my earlier response again. I think the details you need are included, but to try and clarify.

In a very small room like that, you need to cover most of your wall space with treatments. Not necessarily floor to ceiling, but 4 foot panels centered height wise with the speakers. In the corners you will need heavy bass trapping, again I'll recommend floor to ceiling GIK tri-traps in at least 2 corners, and preferably all 4. A GIK soffet trap would work as well, and could be considered.

For the front wall behind the speakers, you'll have about 6 - 6.5 feet of wall left after the tri-traps. I'd put 3 2'x4' panels there which would cover the entire width of the wall. 2" thick panels will work, 4" might be better but more expensive.

Side walls, I'd suggest 2 2'x4' panels per wall, spaced close to each other, and centered on the first reflection point. I'd go with 2" thick panels here.

For the rear wall a diffuser would be the best option I belive. Quality diffusers aren't cheap though, and I'd think you will need about 4'x4' of coverage.

The cheaper panels will work just fine for the most part. Some more expensive panels have things like high frequency membranes, or a wood frame that stands them off from the wall for greater effectiveness. But get whatever fits your budget. You can even make your own for very cheap. I get 4'x8' sheets of rockwool, OC703 equivalent, for about $32 at my local commercial construction supplier ... and Roxul AFB for even cheaper per square foot.

Bottom line is you'll never be happy with that room until you treat it.

To the poster before you, Hew - there's a HUGE difference between a 12'x14' room and a 8.5' square room. I've heard 12x14 rooms sound pretty darn good with no treatments at all, the 8.5 square room however is just about a worst case scenario. Good luck!

I too have a changeling listening room. A heavily treated 12x13x10. GIK Acoustics has been a useful resource in getting things sorted out for not a lot of coin. For my situation I went with their Soffit traps stacked lengthwise in the front corners, 242 style absorbsion centered between the traps on the front wall, three Monster Bass traps side by side on the back wall, and two QRD Diffusers at the first reflection points. All told it reduced the bass nulls, improved soundstage depth an width and provided greater midrange clairity.

Vapor,

Thanks for the detailed response. I am going to start pricing things out. It is very helpful informtaion on placement.

Yes, treatment will help. I get excellent imaging in my 12x12x8 room. Sent the dimensions to GIK, treated 1st and 2nd reflection points ( Including ceiling ) and it still took 3 years to finalize speaker placement.
