You have to use the analog meter per Richard Vandersteen as I just spoke with him last week, my dads wood Quatro's have been moved into a new home so I am going to tune them soon. I am gonna use the Stereophile test disc I have aswell. Richard told me dont worry about the numbers being off on the meter, he explained there is no need to account for inaccuracy. The only thing he added was to start from the bottom and work up from there. When I try this myself I will share my experience.
So far I zero'd all settings and to get rid of a boom lowered the overall level of woofer and it sounds great but will only get better after a tune procedure.
