Greetings, i have used foam from wallmart or any other department store and wrapped material around it. You can leave it flat or rolled to your needs.
Also, have you tried setting your speakers up by finding the center point of your room dividing the width in half and placing your speakers that distance from your seating position at 45 deg. You should end up with your speakers in an arc. Everything should be relative to room size and this should take care of imaging
