Can it be done

[gewaun]

Using this design is it possible to change to subs up with port in the same place. Can it be done? What changes do I need to make it's for 15's.

it'll change your tuning slightly, but its negligible. you'll want to move the extra baffle to the top instead of the front, but other than that, I'd say go for it. just by my rough calculations, it seems that box is tuned fairly high (almost 40hz). if you are just playing regular music, and not much rebass, it'll more than likely sound decent.

Box is from resilient sounds webpage says tuned to 34.5hz. Can anyone with knowledge check for me.

This design is already for 15s looking at the sub cutouts, you just need to do a double layer baffle on top and you should be good to go, you don't need need a double layer baffle where the subs are now.

Im thinking out loud but if you put the subs on the top with a added baffle you will tune lower to 33 Hz, which is even better.

punching those numbers into my box calculator gives me 35hz without any displacements after displacement its 36.2 as its modeled. 36.7 subs on top. not bad, but still a little high for my taste

33hz is my target what needs to be done to achieve that with this plan with double baffle subs up

Extend the vent.

also, you wont even now any difference of a single hz.
