I would suggest you download the well written Vanderesteen manual.
suggests many positions on odd dimension for best in room responses.
Tilt back as in manual with a washer and string as per chair distance indicates.
For best speaker performance they should be level.
For finding side to side level position.
Put the bubble level across the wood strip on the top front of speaker. adjust front spikes until level.
Then do the tilt back with a laser on top of speaker pointed forward
aiming toward the wall behind your listening chair using a sharpie pen with both landing points mark em with a post it note and draw a circle around each laser red landing points.
simply level by adjusting back spike of the speakers till lasers are horizontally equal on both post it notes this your starting point
Read this all the way through it will then make sense.
Listen in all 3 positions first to see which of 3 positions sounds best.
In chair in normal position == if perfect ((leave it alone))
Sit on a pillow and listen == if perfect up there adjust back spikes on both speakers counter clockwise this will begin to correct tilt back towards your normal seating height
listen then adjust both speakers at a time till best tuned.
Slouch low in chair and listen == if perfect down there turn both back spikes clockwise and listen till best tuned for your normal height position.
Enjoy
