[QUOTE="devin171moto, post: 8703970, member: 679009"] I've attached box specifications for reference. target tuning 29hz. (2003 gmc envoy 20H 42W 30D max dimensions) taramps smart 3 amp I absolutely love this box. it slams from 25-40, my only disappointment being it drops ridiculously fast under 24hz (21hz the car has to be stopped for me to even notice the note is playing, subs excurt like a little or half xmax and turn dead silent. ) I wasn't expecting 140's at 20hz from a simple 3rd order bass reflex, but i thought It would at least be some decent vibration I dont have to pull over to feel. questions: 1. is 2 12's even enough cone area to get decent pressure at 20hz? 2. i'm aware of fazing and the size of the 20hz wave making placement of port and subs complicated and crucial, how could this be adjusted for better deeper bass? (will run sweeps to find cabin peak soon) 3. can this even be acheived with a simple ported design? maybe changing to aero ports or increasing internal volume) or do I really need to be thinking about a 4th or 6th order? please no "why would you even tune so low anyway songs don't have dijabndiqdb" comments. because I want to. and because I only really play edited music. deep rumble is what I want. I dont play over 40. I understand I don't know much. but I'm reaching the limits of what I can learn from youtube and forum post research, as at this point most of it doesnt apply to my situation, I'm open to suggestions on learning more detailed box design theory. so please instead of telling me "do your research". realize that's what I am trying to do and point to where I can find that research. thank you all. I appreciate anyone's time [/QUOTE]
