Danham, I was wondering whether to keep my JL Audio sub with the VR 33's? Do you get enough bass for eg, listening to jazz and rock? I don't listen to much pipe organ music so getting down to 20Hz is not an issue but a famous speaker designer and manufacturer told me never to believe the specs: that 30Hz really means 35 Hz and a well integrated sub is the best way to go. "Well integrated" is of course much harder to do than say.
