Thanks Matts for the reply ,What do you refer as to the super lows like the 20-30 hertz range. I dont like rumble you could cut it off at 35 hertz for me. I like a punchy bass but no rumble ,I had a jbl 15 inch powered sub, it was mostly rumble to me .Gave it away to get rid of it. It did put out the lows but it all sounded like a octave too low for me. To me the 12 inch jensen sounded a lot better but no definition same tone on any bass note.
