April 2, 201015 yr No Im not far from it, Im still a beginner at this whole box stuff so I dont feel my advice or info would help much
April 2, 201015 yr Is that 35hz the frequency you are looking to tune it to? Youre doing a double baffle, right? Are you doing any bracing inside also or just the double baffle? You may want to try to go a little larger on the port area. Are you using any wall of the box as one of your port walls?

Are you using any wall of the box as one of your port walls?well im really looking for more like 32hz, but dont know how to get ityes there will be an extra baffle cos i dont think 1 3/4" mdf sheet can hold the 18" btl haha, i have 2 on my current boxno bracingsee i just dont know exactly what measurement is whichis this the right measurement structure?

Your H would be the height of the port ( not what you have labled ). The W is correct how you have it labled. The L is partially right but in your drawing it would be L+H not just L. In your current design you will not have a bend like that and it would be nice to know if you are going to use a wall as a port wall or if you are going to center it in the box. Using part of the wall as a port wall would be like what you currently have. You may want to look into atleast adding 45's in it like you have in the picture of the box. To get 32hz you will need to change the length of the port, but I can't tell you exactly how long until you say if you are using part of the wall as or port and if you are going to do a little more bracing or not ( The BTL is heavy so you should really consider it ).
