teardrop Posted February 28, 2012 Report Share Posted February 28, 2012 im going to be doing some free box desings but as of now no kerfed ports or aero ports i havnt figured out how to do that in sketchup or to tune it proprly with kerfed ports and aero ports but any 4th orders or ported boxes with round or square ports i will need to know subs make model and specs amps make and model max deminsions subs and port direction i tune to 33 hz if you want deferent let me know and i try to lean toward the bigger size boxs i like the way they play the lows and it leaves room for bracing if you feel like you need it i will try and do them in the order that i receive your info Link to comment Share on other sites More sharing options...
412 CVX Posted February 28, 2012 Report Share Posted February 28, 2012 not that hard to do either in sketchup prepare for a wave of requests lol Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

Sergeant_Skyrim Posted February 28, 2012 Report Share Posted February 28, 2012 2 Kicker Comp 12s wired down to 2-ohms MTX RTP251D pushing 200 watts at 2-ohms Max Dim: 33Wx14Hx28D Both subs and port facing forward from my trunk Random Info: -I'm looking to have the port in the middle of the subs -Looking to be as close to 3.75 cubic feet net after all displacements -I will be doing a removable port, so the original dimensions I'm wanting to have around 16 sq inches of port per cubic foot and then will use 0.5" thick MDF in the removable port that, when inserted, will decrease the port dimensions by 1" on H and W. This should bring it down to around 12 sq inches of port area per cubic foot of box. -I'd like to use the 33Wx14H and have 0.25" of spacing around each sub and a 5" wide port in the middle of them. So 12+12(subs)+(0.75*4 for each piece of wood going deep)+(0.25*4 spacing around each sub)+5" port=33W -Would also be 12H for each sub + (0.25*2 spacing) + (0.75*2 wood thickness for top/bottom piece)=14H -Been trying to tinker around with the equation all morning, I'd have to keep it to where there's no bend in the port if I'm looking to have a removable port. If you can help with this then cool! EDIT: Forgot to add that I'm looking for a low tuning with the removable port in, so probably around 30Hz and then a bit higher of tuning when it's not in.
