What I did was use an 87Db speaker as a reference with pink noise and then compared the level to the home builts which were 6db hotter. I used a speaker of higher sensitivity rated at 100db and it was 4db hotter so you are correct that the absolute is not right. 93 from the lower measuremant and 96 from the higher. That comes out to a 3db error between measurements. I am at 95 which gets me within a 3DB window if I split the two. You are good!!! I did not look at it that way before.

Thanks for your help.
