You have it right now Scamp. I understand John's concern about the calculator not having something specific for room gain, but if you understand how the formula works, you can add it in where appropriate. Axiom just adds it to their sensitivity number.
I can't say I have ever listened to something at an average level of 90 db in my livingroom. I usually listen between 75 and 85 db depending on my mood. 90 just hurts (I did try it with spl meter in hand).
John. I'm trying to picture you with an spl meter in hand at a concert. Quite funny!
