[QUOTE="jimmyjames1700, post: 1494472, member: 558886"] I disagree. In the realm of vehicles you get such a huge LF gain from the vehicles natural transfer function that a low tuned enclosure (say around 30Hz and less) has a way over emphazised low end that it adversely affects transient response. Not to mention that generally the lower you tune a vented enclosure the more you will encounter group delay which also affects transients. I think that if you crave some extra thump and must go ported but still want the good transients, you are best of tuning the enclosure around 35-40 Hz or even slightly higher. Just be sure to not over size the enclosure so you can control the ripple around the tuning frequency. A sealed enclosure is the best suited for a vehicle because they hit thier -3dB pint higher and get a perfect compliment from your own car. Just the opposite for a house however where you desire the lower -3dB down point and lower excursion. [/QUOTE]
