I just moved my VP150 under my TV and I am wondering if the "upside down" position (pointing up) is best.

First Question, does anyone know the exact "angle" that the face of the speaker is at in the "pointing up" position?

Second question, my math skills are failing me. Assuming I get the angle of the speaker and I know my listening position is 9 ft from the speaker and the speaker bottom is 21-1/2 inches high, at my listening position where is the sound (my guess is it feels like its pointed well over my head, ear height is 33 inches)?

Thanks in advance for any help on this.

I tried flipping it as you suggested when placed below the screen and felt it generated too much treble energy that way to properly blend with the left and right. It sounded noticably different than the fronts in that orientation. When I flipped it back, it blended better.

Point it at your face.

Listen.

Adjust as necessary.
