room tuning 12ftx12ft room

Rrog is most likely right about the speakers. Seems he's pretty familiar with them. On the other hand, Hornguys advice should be tried as a last ditch effort. Here is some information on why that set-up may work:

Read the entire article. I've used it before in a very small room with speakers that could be considered too big for the room. It worked quite well. At some of the audio show where rooms are somewhat small people like Roger Sanders and Kara Chaffe use this type of set up. Worth a try IMO.

G19276, your room dimensions are similar to mine. You will not get a room this size to allow a speaker to plumb the depths of 30hz or below reproduction. However, you can enjoy great imaging and intimacy of reproduction with a few tips that helped me greatly. Firstly, I do agree with the posters who say you should try and get the speakers about 1/3rd into the room. The other trick is to apply bass trapping on the wall behind the speakers and as much diffusion as possible on the wall behind your seating position. The Vandy 3's are probably not a good speaker for a room this size, although I suspect you can get them to basically work, but with little bottom end extension. A better suggestion is a small monitor like the SF's I use or maybe Merlin TTM or ?
I also get great results with having the speakers with zero toe-in. Toe-in can be difficult to get right in this size of room, so if zero will work, then that should be tried first.
Is your room a dedicated listening room?

I read Frogs well intended suggestion in G19276 other thread
but disagree....
Why would anyone want to settle on a less natural sounding 2 way mini box when all you need to do is kill any excessive room overload with a simple Vandersteen assessment x over box and later insert the proper x 2 for uniform in room response.
We Have installed 2 and 3 Series in 12x14s and square rooms for years with fine results.
Try the Vandersteen X 2 Box and it will work like a charm
Start at 20 K and work up till speakers disappear.

Try the 45 degree or angle speaker placement.

Go to the DecWare site, and look at the section on room tuning.

You can tame a bad room with this technique,and use a minimal amount or no dampening at all.

Your speakers are not too big for the room.

I know most people aren't familiar with this type of speaker placement and it appears odd as most like the conventional type speaker placement .

But what are you after, style or sound?

This is audio, not home decor.

I should add, my room isn't much bigger,11.6 x 22 x8,and I use Ref 3a Grand Veena full range speakers.

A friend of mine using Spendor 1/2 speakers has also made an improvemnt in his sound when he set his room up like this, and he has an even larger room.

I doesn't cost anything to re-arrange your speakers.
