can the bass boost act as a crude subsonic filter if the amp doesnt have one?

[QUOTE="realflow100, post: 8675276, member: 676243"] I'm not in a car im in home. everything setup in my bedroom I have no bass boost set. turned off completely. my box is ported tuned to 34hz and not sealed. it hits down to about 22hz strongly. my subs do not even get close to bottoming out without subsonic filter. even playing a 20hz sinewave at full volume my subs still have plenty of overhead excursion left. they arent even being stressed when playing music. they start dropping off in excursion below 20hz and above 20hz without a subsonic filter. only have low pass filter set to 40hz on both subs so they dont play any high frequencies. even though its tuned to 34hz. it sounds the loudest around 45 to 50hz so i set an EQ on my computer to account for that and reduce the bass around 40 to 100hz and reduce the peak at 45hz by 15dB and 50hz by 18dB to make it sound flatter and less boomy. my room really resonates loudly around 45 to 50hz it sounds like my head is in the subwoofer port when i stand across the room from my subs unless i have my EQ filter on my computer set to reduce the peak around there. I prefer SQ over SPL so it sounds really good the way its set up right now. i would need a subsonic filter if I got a more powerful amp for sure. the amp i plan on getting rockville dB14 comes with a subsonic filter already so i'll be using that if I give my subs more power.
