Hey Steve
Did you ever do the laser tilt?
Most floors are never level.
After you have read the Vandersteen manual and are in the zone,
Use a bubble level confirm the speakers are level side to side,take a laser pen aim it on the wall behind listening chair area. Get a black sharpie pen with a post it note, draw a circle on the target O where the laser lands post it note stuck to wall.
Next do the same for the other speaker and make sure both speakers have the same bulls eye tilt landing on the O bulls eye?
Sit and listen,then slouch down in your chair,then listen sitting on a pillow.
One of the 3 positions will have magic.
Then adjust the final tilt to where your normal seating position is and make sure you confirm both speakers are in the new final bulls-eye.
Please let us know when you find it.
