D-train-13k Posted June 12, 2011 Report Share Posted June 12, 2011 and about that gap. ive never encountered having to have the gap for the external aero. but i would think that the sound would resonated the port. making another noise in the gap in between the box. almost like a tuning fork. and also i think your going to need way more port. especially for a level 5 12. i have a level 3 12 in a fourth order with an external port and i actually need more port area. i know with aeros you can take off a little because of the design. but IMO i think more port is neccessary. especially since most of the sound comes out of port. anyways. also another thing to think about. ive never owned a level 5 but ive heard numerous times that they dont like the sealed boxes to begin with. so inverting the woofer would allow for a more even pressure on the cone itself. (thats just a thought i have about it, idk if its an actual concern) i guess thats some stuff to think about.

P4killer_ Posted June 12, 2011 Report Share Posted June 12, 2011 not to thread jack but i out 45's in the 3 corners.. back on topic, im tuned just to see what you do. small 4th orders are a pita to get figured out. if you mount inverted good f'in luck mounting it with that huge motor in the way... edit idk if the triangular sealed portion is ideal.. but it certainly makes building it simple. i just thought of it, drew it up and decided wtf why not.

P4killer_ Posted June 12, 2011 Report Share Posted June 12, 2011 i guess... but loading in an 80lb baffle or w.e it weighs and positioning it with a huge weight hanging on it would be tricky but with patience it could be done.. what happens when you want to take it out...the baffle is in there now with minute room to work.. i mean you could build it however you want if you plan on sealing it up and then its permanently glued and taking the sub out means tearing the box down, but having the ability to remove the sub and invert it if you choose or change sub or w.e and still have a functioning box makes it a lil tricky Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s Link to comment Share on other sites More sharing options...
woodzyspl Posted June 12, 2011 Report Share Posted June 12, 2011 LOL i got this sub so cheap it aint funny,im probly just gonna blow it after i do some runs with it on some decent power i hope, tryna get a loud trunk car firing through rear (i got fair bit of room in trunk Australian cars FTW) AUSTRALIA do i need say more?
