Help with room and equipment placement please

I just moved to a new apartment where my listening room is not the best 18x12. I packed all my audio in the long wall including my AZ Crescendos and my Luxman 550 AX 20 Class A amp. I have no problem listening at low volumes near field but I would like to hear from you guys if my gear is ok for this size of space.
I also own harbeth C7 but i prefer full range sound. when I seat the distance from each speaker is around 7.5 feet=90 inches.
All inputs highly appreciated.
Thank you
