I can’t quite visualise what your current arrangement is. Whichever way you orient the speakers, the ideal to try for is an equilateral (same length sides) triangle between yourself and the two speakers.
If you face sideways across a narrow room, you will need speakers that can work quite close to the wall on one side of the room, and somewhere to sit on the other side facing them.
Facing lengthways along the long axis of the room, you have more flexibility to bring the speakers and your seat away from the wall at each end, which can be better, but they will closer to the side wall as a result, which can cause reflections.
You will probably have to experiment a bit. If you google loudspeaker room placement, there are various guides and instruction which might help.
