pervitizm Posted May 8, 2009 Report Share Posted May 8, 2009 (edited) My 18's are currently in a dual port/seperate chamber box that is roughly around 11.5cuft after displacement is factored in. I want to do a single port common chamber box. I was floating around with a folded horn idea but I don't think I have enough space in the back to do this, since my goal is to try and keep all my seats in the truck. I roughly have the following outside dimensions to work with. 25in Height x 26in Depth x 49in Width You guys think I can do something other than a normal vented enclosure within the restrictions listed above? I figured I'd ask around here first before I start messing with sketchup. My current box is tunned to 34hz so I want to try and stay around the 30 - 37hz range.

wierdguy75 Posted May 18, 2009 Report Share Posted May 18, 2009 Whats your question? You already have your box specs for the new one. So build it and port it like u want. Ps. Fuck off. Quote Link to comment Share on other sites More sharing options...
banginAltima Posted May 18, 2009 Report Share Posted May 18, 2009 That would be a no on the folded horn unless you want to wall it. As far as a regular ported box a common chamber will be better. The size you listed should give you all the room you need. Double up all the sides you can with some good bracing. Quote If you build it, db's will come...

pervitizm Posted May 28, 2009 Author Report Share Posted May 28, 2009 Bumping this up. I've been so busy that I haven't had time to really sit down and think up some designs. I have one that I was kicking around back in the fall that I want to re-visit. Now when I plug in the numbers using Expo's Box Calc program I get a really high tuning. Close to 60hz, which is not what I want. However when I use this older excle program that I also got from here my tuning comes out to 33hz. What am I doing wrong?

pervitizm Posted May 29, 2009 Author Report Share Posted May 29, 2009 I did another design last night, this one is somewhat bigger than the last one posted. I have the following for outer dimensions: 25.75 x 49 x27 Now my drawing shows a height of 26 1/2, but I'm only counting the height at 25 3/4 in the Box Calc program because the top board was double baffled. I'm seeing a box tuning at 33hz. I think I still like the whole port and subs up design of the first box I posted last night. Has anyone gone from running subs up/port back to subs up/port up and if so did you like the outcome of that change? I've always ran subs up/port back and don't want to go through the hasle of changing to subs&port up if my output will suffer.
