how does this look?

Used the RE calculator and it is confusing me a little bit. It is saying 4.58ft^3 volume with 105 sq.in. of port but when i do the math I get the volume shown in the box (in the drawing)... Sayd the tuning is 42Hz~ which is exactly what I am looking for but I wanted to make sure everything is good since I am getting conflicting numbers on teh box volume...

Box is for a Mach5 SPL15

105 sq of port for one woofer seems a bit much to me

looks loud!!

I get 6.14 ^3ft before speaker and port displacement.

I took a wild guess and used 0.18 ^3ft for speaker displacement and after port displacement I came up with 5.093 ^3ft tuned to 46hz

I did this quick so somebody may come up with a more acurate number for you.

The only other reply i got was that it looks like 47Hz so you must be close... as for sub displacement, i have no idea, it's a Mach5 SPL15...

I guess I can just tweak the port on the RE calculator so it says it is tuned to about 36hz~ and that should get me to the actual 40hz-42hz I am looking for.... Kinda of a crappy way of doing it but i thikn that 46hz is a little too high... 40hz`42hz is my basic goal. Just looking for an SPL monster

You can add an L shape length of 4.5" and that should get you close to 42Hz.

What are you using to draw the box like that?
