Much has to do with the quality of your sub , I went from the $500 Svs pro
to the 1000sb $1000, to the $svs 4000 sb $1800
and the 1000 had much more control and articulation ,
then to the 4000 SB-Sealed box. It took it to another level altogether the bass much faster,more articulate and controlled. ,No boom whatso ever .
you didnot mention what subwoofer you were having issues with.
