Can you layout your room to where you can place your speakers across the 18' dimension?
If you could place your speakers 4.5' away from each wall, that would give you 9' of spacing between the spkrs. Place your sitting area on the back, or very close to, the rear 18' wall. You'll have to play with the spkr distance off of the now "front" 18' wall. Avoid placing them at the 4.5' location , because that would have them (the front/center of the drivers) equal distant from both the front & side walls, which can not be so good. Try starting about 3' out. Ideal should be at the 5.5' mark. That will give you a "nearfield" setup and pretty much remove the first side-wall reflections.
If you can work with that arrangement, you'll be suprised at the soundstage and imaging. You'll have to make several adjustments to the toe-in, depending on your speakers. Having a $19 laser level from Home Depot helps tremendously in getting both spkrs set evenly.
If you try this, get back with your listening report?
Good luck and happy listening!
