Without having enough info of your speakers positioning i would suggest to move them a bit forward in the room and try to get them a bit closer together. From there you can listen if you want more toe in or not.
As you do not have a sub and you receiver has basic eq features you can only play with speaker placement for getting a more enjoyable sound for both music and theatre.
