budz, you seem to be convinced avaserfi needs a new sub. you push HSU, I'll push SVS. let's see who wins
i'll start:
avaserfi, I know the reason why your frequency response is so messed up, you don't have enough output from 40-80hz! the PB10NSD has oodles of output in that range! look at your chart, it slopes in the wrong direction! it should be going left not going right!
SVS! SVS! SVS!
