I measured mine today with my SPL for about 4 1/2' in each direction from the center of the couch. I could see the needle start dropping when I moved the meter past the arm of the couch in either direction. the dropoff starts about 6" past the armrest on each side and hits -1db at about 1 foot past the armrest. The 150 is just about 10' away. It has the same exact SPL reading at all 3 seating positions on the couch, and it sounds the same at all 3 positions. My ears seem to be telling me the same thing as the meter.
I'm not sure if this is exactly what Tony tried, but I think it is. He had me worried, as I had already ordered mine when he posted his issues with the VP150. I tried it with Avia and the built in test tones on my HK630. (-10 db volume setting, calibrated all 5 channels to 85db)
Maybe I'm just a noob testing it wrong as I am definitely still in the "learning" phase here. Are -10 and 85 the correct levels to calibrate to?
I love my VP150.
