their meter isnt a termlab either but ive been told it only .5-2 db higher then the termlab would meter it at and i dont know the brand or make of the meter they use right off hand its been a lil while since i was asked anything about the meter that is used. and the first box i built only had about 9 sq in per cu ft of port, i made it before i knew anything about actually designing a box. i actualy used the measurements and everything that came in the manual for the box. i was told shortly after building that box that the port area being so small could easily make it meter lower.
