98crewcab Posted January 30, 2010 Report Share Posted January 30, 2010 (edited) what up homies.........thanks for looking in on this. Building a new enclosure today and have a couple questions. Appreciate any feedback. its for my 4 type r 12's. Blowthrough that is double baffle 1 1/8" mdf (2 1/4"), back is 1 7/8", and sides, top, and bottom are all doubled up 3/4". designing some bracing and will end up with 9.2 cubes after displacement of subs and port. Internal measurements are 61 5/8 wide, 16 tall, and depending on your input, will figure out depth. I am running about 750 rms to each sub if that helps. my questions are... 1. can I run part of my port in the box, and let whatever remaining length I need run out of the box? Inverting subs, so can design to look good with them (only thinking this because I cant go deep enough to get a 21 ish port length without raising my box volume.... 2. and with 120sq" of port, 9.2 cubes internal volume, what length does my port need to be to get 34hz? I really appreciate your help and will be starting a build log soon.

raytard Posted January 30, 2010 Report Share Posted January 30, 2010 you can run part of the port out of the box and it will work fine. you can also make it into a T style port, just make the part that uses the back of the box 1/2 the width of the main port, and a little V in the center to help direct air couldnt hurt(or even splitting it in half and making it into two L ports) and as far as tuning you're right on, about 20-21 inches of port will get you down to 34 hz, give or take a bit each way. i'm sure you can do the volume measurements for the internal and whatever port style youre going with, youre basically looking for 9.6 net internal, a port thats 120sq in by 21 long. make the depth whatever you need to compensate for where the port is going and whether the subs are inverted, but you're probably looking around 25 inches (give or take again) Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...

KHARPS Posted January 31, 2010 Report Share Posted January 31, 2010 I'm loving the look of the box. Great start so far! Quote Link to comment Share on other sites More sharing options...
Boon Posted January 31, 2010 Report Share Posted January 31, 2010 I can't believe you can get 4 12's and ports across... you guys are lucky with your huge-ass cars. I can just barely get 2 15's across most vehicles here and then I have to put the port on a different face... Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
