[QUOTE="Papermaker85, post: 6994116, member: 572595"] its amazing how many people use woofers in the wrong alignments. they are excellent performers with one exception.. FS is to low to excel in a car cabin.. if they would use a FS around 26 to 28 efficiency gans would be substantial and alignments would be more along the lines of you normal designs we use.. Now one thing i can say is they are very transparaent.. excellent sounding subs with a F3 of 22hz.. the spiders are extremely linear but soft so ported enclosures are much harder to design but the benefits are loss of efficiency for wider bandwidth and lowered group delay which plauges most ported alignments.. when i design a woofer i try to get good efficiency within the usable bandwidth keep mass low as possible and keep power compression and inductance low as possible. that much easier said than done.. you can have all those factors perfect and spider geometry can kill the speaker.. all in all if you where to use it with a PR in 1.5 tuned around 28 its truly a nice woofer.. sealed 1.25 to 1.5 is plenty..
