need help badly! and quick

ok, did some testing today with my redesigned no-wall box. started with no angles in the box and no port lenght(just the 5.5" thick baffle)

tuning-57hz, 152.06db

added one angle behind the subs,

tuning-58hz, 151.8db......(i think i raised my box rise, didnt test though"

added small round in corner nearest the vent,

tuning-58hz, 151.9db

it seems frikkin loud, the spectrum analizer on the tl is readin the freq accurately, BUT the scale showing the db level says its near 157??????

does anyone think my meter is fuggered?
