berniebp87 Posted July 16, 2010 Report Share Posted July 16, 2010 Hey guys! I`m about to start my first wall build and I want it to be a really good one. I have some experience with box building, but from what I`ve heard and read, when building a wall, things change. So I need your opinions/thoughts about this. I`ve crunched some numbers and done some work on sketchup. These are going in the wall btw Here`s the box, net volume of each chamber is about 7.4 cubes, 32hz tuning according to Torres calculator.

memphisBred Posted July 16, 2010 Report Share Posted July 16, 2010 Never built a wall or even seen one in person, but I would do some 45's in the corners and some dowels for support. Also I bust a nut every time I see those woofers Quote SMD Super Seller/Buyer Audison----Hertz----Rainbow Link to comment Share on other sites More sharing options...
OrionStang Posted July 16, 2010 Report Share Posted July 16, 2010 Im working my first wall now and let me tell you , its a learning experience. Im happy I tried it, not happy the way its turning out. Learned a whole lot doing it. Your enclosure looks good. My dimensions and net volume are good, but getting the front baffle to sit and fit right is my biggest issue. It'll be loud, but not very pretty. Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...

Hope to get atleast a 155 with the new setup.

berniebp87 Posted July 16, 2010 Author Report Share Posted July 16, 2010 EDIT- maybe invert the box so its port on top subs bottom What diffirence does that make? just curious Never built a wall or even seen one in person, but I would do some 45's in the corners and some dowels for support. Also I bust a nut every time I see those woofers Gonna do some 45`s where needed, don`t think I`ll need further reenforcement, as the walls are gonna be 2.5" thick with seperate chambers.

dwright27 Posted July 18, 2010 Report Share Posted July 18, 2010 I'd do port on top.

superdave07 Posted July 18, 2010 Report Share Posted July 18, 2010 Im on the fence with my wall here also, cant decide weather to do woofers on top or port on top. What do you all think sounds better? I personally am not going for numbers just moving a lot of air. Dont mean to thread jack hope it helps you also!
