pssstgotbags94 Posted June 3, 2012 Report Share Posted June 3, 2012 I just got a DC level 5 18" sub. Right now its in a shotty box thats way too small and has a piece of 8" pvc pipe for the port that sticks out of the box about 6". Now it's loud as hell but I really want to build a new box with a slot port. Here's the dimensions I have to work with. 44" long x 24" tall x 12.5" deep. I want it tuned to around 32 to 35 hz. I have no idea how to figure out how big to make the port and how long to make it. I used the pinned calculator up top and came up with a 2" wide port thats 22.5" tall and 18" long. Here's a quick drawing using paint (please excuse my horrible paint skills lol). and here's the results of the program I used. I know I didnt get it right. My front plate will be 2 pieces of 3/4" MDF for the sub to mount to.

john253a Posted June 4, 2012 Report Share Posted June 4, 2012 you are going to need a bit more space then what you have, unless you run a small, real small port, you either need to wider taller or deeper also with 12.5" that 11.75" and you sub is 10.5, that's not much room Quote Link to comment Share on other sites More sharing options...
Team Bassick - Kimo Posted June 4, 2012 Report Share Posted June 4, 2012 1ST OR 2ND GEN S10? You competing with it? Musically and for decent numbers I always recommend flared ports. For this application I'd run 2 6" flared full lengths and corner load them and woofer firing up. You could do woofer forward and port up. In that configuration I'd use 4 4" flared ports. You'll move a lot of air and sound good but, lose numbers metering. I have lost count how many boxes I've built for my s10 but, my loudest single woofer set up was 1 18" woofer and ports firing up. It sucked for driving around but, it was loud. Quote KIMO @teambassick http://www.teambassick.com Link to comment Share on other sites More sharing options...
pssstgotbags94 Posted June 4, 2012 Author Report Share Posted June 4, 2012 (edited) right now its the same depth but not as tall or wide as my idea and its sub forward with port firing up. I don't like the round PVC ports. Can't I just do a square port like Steve uses? My problem is I have no idea what to build. And yes it can be bigger but I'm already uncomfortable with the depth its at now due to losing so much leg room. Someone feel free to show me idea's with hopefully a cut list and how exactly to do the port to get the tuning I need. Oh and its just a system for fun. But I may have it put on a Mic and its a 98 2nd gen Edited June 4, 2012 by pssstgotbags94 Quote 2004 Nissan 350z slammed on topspeed coilovers pioneer appradio B2 audio Quota for sub B2 audio HN15 sub Lunar L2200 for highs Infinity kappa 60.9 components in doors Under construction still.

pssstgotbags94 Posted June 4, 2012 Author Report Share Posted June 4, 2012 Not ready to go permanent like that. This is my first time with anything better than kicker lol. I'd like to just built a nicer box than this pos I'm using now and see what it does with 2 more cubes tuned better. Right now it has 3 cubes and tuned at 40 hz. The box is coming apart and rattles all to hell. It's loud as hell for me and is hard to breath when it's hitting.

pssstgotbags94 Posted June 5, 2012 Author Report Share Posted June 5, 2012 Any help? I'm buying wood tomorrow. I know what I need to build but have no idea about port. I'd like to do an up firing square port but need to know dimensions i need to cut to make it.

Joe X Posted June 5, 2012 Report Share Posted June 5, 2012 (edited) New suggestion hope that is suitable: Enclosure Specifications: Fb = 35.4 Hz Vb = 6 ft^3 External Height = 25 in External Width = 44 in External Depth = 14.5 in Port Width = 6 1/4 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 44 x 25 Left & Right Sides = Side 1 = 23 1/2 x 12 1/4 Side 2 = 24 1/4 x 12 1/4 Top = 37 x 12 1/4 Bottom = 44 x 12 1/4 L Port Internal Assembly Parts: Top to Bottom = 16 x 12 1/4 Edited June 5, 2012 by Joe X Quote Link to comment Share on other sites More sharing options...
pssstgotbags94 Posted June 5, 2012 Author Report Share Posted June 5, 2012 That's exactly what I want except instead of gaining more cubes from going up ( I want to keep it flush with bottom of window) can you make it deeper? I'm willing to sacrifice more leg room. Can you do it like 14"-15" deep? However much you need to get the right air space. You can see how much I have between the current 12.5" depth and my console to work with.
