Magnepan Sweet Spot


For the last year, I have been listening to my set of Magnepan Tympani IVs.  They are great at creating a wall of sound, and picked up substantial bass and detail when I acquired a Parasound A21.  However, I have failed to create the sweet spot I have experienced with other maggies I have owned.  Between this failure and the size of the Tympanis, I am considering selling them and looking at other Magnepan models to achieve the sweet spot. I have always loved the Magnepan clarity and detail, and do not need thumping bass.

The current Tympani arrangement has them at one end of a 22x12 room (12' wall behind them).  If I change them out, I think I will rotate the setup, so that the listening chair will be at one end of the 12' wall and the speakers 3' - 5' away from the other wall.

Given this setup, which of the Magnepan line should I consider to achieve that sweet spot??  I have MMGs but would probably get the LRS if I chose that size speaker. 

Heresy though it may be, if I turned away from the Maggies, what speakers would achieve similar results for about $2500 used?

kythyn, if you rotate the system your listening chair will be up against the wall which will exaggerate the bass. I would keep the system on the 12 foot wall. Have you set the Tympani's up with the tweeter panels to the outside? If not please try it. toe the tweeter panels in so that they point directly at the listening position. They should be three feet in front of the wall. The woofer panels will block the primary reflection so do not use any treatment behind the speakers. 
If this does not work for you look for a pair of 3.7i's
My first call would be to Magnepan.
They have great customer service and should be able to direct you in enhancing you speaker placement.
Second, I would consider some room treatments. It sounds like your room might have some issues. 
I love the Maggie sound, but unfortunately, don't have the space.

Magnepans are incapable of creating the phenomena of the more localized phantom image, the illusion that the central part of the performance is as "solid" as the L/R channels. I reviewed the .7 for Dagogo.com

Having owned Maggie MMG and 1.6QR, as well as Eminent Technology LFT-8A/B and Kingsound King and King III (The ET and Kingsound were reviewed for Dagogo.com) none of them create the focused phantom image that you are seeking. 

Placement can help with the width and to some degree of focus, but it simply is not capable of the same kind of localized imaging of a dynamic or horn speaker. You will lose much of the grandeur of the music by moving to smaller Maggies, which is a rough trade-off.  

I am not interested in arguing/debating my discussion.
douglas, then why say it at all? Line source speakers produce a larger image than point source speakers which many of us think is more realistic. You disagree and that is why Howard Johnson's made 28 flavors. Planar Magnetics still have a sweet spot and it should be easily noticeable. Having had Tympani's I know for a fact they will image appropriately if set up correctly. No they will not produce the lilliputian image you seem to like but they will produce the life like image I like and kythyn will have to determine on his own if it is for him or not.
