[QUOTE="MrBill2U, post: 765564, member: 553080"] On my JL 500/1 the bass boost knob drops all the way to 20hz... I have tried tuning it for "freakishly huge lows" before and dialed in +15db at just under 30 hz with a Q of .5 and the subsonic filter tuned to 20 hz. This was through a 12w6v2 in 1.5 sealed cubes. It went deeeeeeeeep and hit hard. On a sealed box you pretty much do not have to worry about blowing your subs with deep bass response as long as your amp is rated near what your sub is... with the ported box I would set my subsonic filter to just below the tuned frequency of the box because under that tuning frequency the box does not act like a spring for your sub any more (read "POP goes the sub"). If space wasn't limited I would say go ported, but with limited space I would run sealed with huge boost on the amp (or some alpine H/Us have a parametric EQ which will let you dial in boost in the sub-bass range).
