I owned a pair for years - sold them to a good friend of mine as I did not want to see them go too far away. I did not use spikes, but think they would be worth a try. The "generally accepted" approach to placement back when was to put them 3'+/- from the back wall, and NOT to toe them in - keeping them parallel to one another.
Frankly, I never found these to be too placement sensitive.
Good luck, and good listening.
