You know im very confused as i thought this was a build log. And i dont see the sense in arguing about this ****. I dont the the tech terms but from my uderstanding the tl measures from 20-80hz right? well most mids and highs are on the above 80hz which is y they dont register on the tl. But there is such a add on on the TL thats called RTA and im pretty sure it adds all the freq together for a total db. but thats in the psyclone class iirc.
