[QUOTE="SlugButter, post: 8863977, member: 678073"] 8th order enclosures work best in home theatre. They aren’t really necessary in car audio because of cabin gain, although who cares, Id try it just for fun. In a good home theatre setup, the enclosure will be tuned extremely low (low 20 HZ tunings), which can cause a bandwidth issue on the upper bass frequencies. In a 6th order for instance, you’ll only get around an octave of bandwidth coverage, so if you’re tuned ports are 25 HZ and 55 HZ, you’ll basically have no output above 60 HZ or so. An 8th order adds a 3rd air spring and tuned port so you can get output up to where your musical/high frequency speakers can take over, yet still tune extremely low to reproduce subsonic frequencies.
