You would probably get better response in the Car Audio section since this looks like a car audio sub & box. This section is for Home Audio subs.
You will also need more specific info on the subs (model number or thiele small parameters) and box (cubic feet per sub, port length/tuning, etc)
Also that looks like a bandpass box, those are good for maximum SPL but only for a narrow frequency range. Not great for overall sound quality. May not be a good match for the subs depending on specs. Good luck!
